The Two-Over-One Game Force System is an improvement over the Standard American System that has been in effect and played by bridge players for many years. The advantage of the 2/1 System is that it allows the partnership to know that game is possible with only a single bid. I have presented the fundamental aspects of the bidding structure in this book.While many players claim they play 2/1, this is not the case. They have allowed the bidding structure of Standard American to prevail, like bidding suits up the line or ignoring the Walsh club. I have tried to change behavior by presenting a series of bids geared toward the 2/1 bidding structure where simply stated means that any auction that starts with an opening one-bid that is followed with a response at the two level of a lower-ranking suit represents a game forcing bidding sequence. Included in the book is Bergen, Reverse Bergen, and Combined Bergen raises, inverted minor suit raises with crisscross and flip-flop, cue bidding, modified scroll bids, and a Modern Splinter Convention. The Chapter on Slam bidding has been expanded to include asking for aces and kings simultaneously, the Baron 4NT convention, expert Gerber, and more. Material on Roman Jump overcalls, the Mc Cabe Adjunct and the Reverse Mc Cabe Adjunct, Bergens Jacoby 2NT bids, Meckwell major suit bids and Meckwell responses to minor suit openings, minor suit Stayman, Kokish Relays, Tartan Weak Two Bids, The Walsh Club Convention, the Principle of Restricted Choice, additional methods for interfering over the strong precision club bid, Variable Roman Keycard Blackwood, Spiral Scan bids, the Swedish 2NT bid, and the Modified Blooman convention when interfering over strong or weak notrump bids. Also included is an update of the Minorwood and the Roman Keycard Blackwood Conventions, Two-Way New Minor Forcing with modified Wolff Signoff bids and new bidding sequences using Mini/Weak notrump. The topic of Offense to Defense Ratio (ODR) is included in this revision as well as expanded bidding sequences when opening and responding to the bid of 2 playing the The Two-Over-One Game Force System and new Bridge Rules have been added to Chapter 10. Finally, four-way transfers as played by experts, the nebulous 2 convention, a 1430 6-pac RKCB Convention that does not require the queen asking bid, hand evaluation using Zar points, and the use of vacant places (spaces) when playing a bridge hand have been added to this edition.You may find Timms Bridge Bits, and several duplicate bridge lessons, and a free .pdf copy of this book on the web site www.bridgewebs.com/ocala.

Hand Evaluation, Opening Bids, and Reb ids
Hand Evaluation – Starter Points
The standard deck of cards for the game of bridge contains fifty-two cards. The cards are organized into suits - spades ([A]), hearts ([B]), diamonds ([C]), and clubs ([D]). The sequence spades, hearts, diamonds, and clubs represent the rank order of the suits within the deck. Thus, spades is higher ranking than hearts; hearts is higher ranking than diamonds, etc. The major suits are spades and hearts and the minor suits are diamonds and clubs.
Each suit contains thirteen cards as follows:
A K Q J 10 9 8 7 6 5 4 3 2
The Ace (A), King (K), Queen (Q), Jack (J), and 10 are called honor cards.
A bridge hand is created by dealing the fifty-two cards to four players, one at a time, so that each player has a total of thirteen cards. Partnerships at the game are the two persons sitting North-South and those sitting East-West. To evaluate the value of your hand, independent of rank, the standard/traditional method promoted by Charles Goren in the late 1940s is to assign values to the honor cards:
Honor Value
Ace 4
King 3
Queen 2
Jack 1
Ten 0
______________
10
The evaluation method is referred to as 4-3-2-1-0 point count system. Using this method, one observes that a bridge deck contains a total of 40 High Card Points (HCP). Hence, an "average" hand consists of 10 HCP. While the method of assignment is accurate, a computer analysis of bridge hands shows that the point count system (4-3-2-1-0) tends to undervalue aces and tens and to overvalue queens and jacks. Only kings are correctly valued. Using only HCP, a hand with at least 12 HCP is usually opened. More later!
To compensate for the over and under valuation using the Charles Gore standard or traditional method, Marty Bergen, ten-time national champion, developed the ADJUST-3 Method. His 2008 book, "Slam Bidding Made Easier" published by Bergen Books, devotes the first 100 pages to his proposed method. Why adjust three? Because the accuracy of the HCP in a hand depends on the difference of overvalued and undervalued honors by the value of three.
Let's see how the process works. With a dealt hand, one goes through six simple steps to employ the Adjust-3 Method:
Step 1: Add up your HCP using the table presented earlier
Step 2: Count the number of aces and 10s (undervalued honors).
Step 3: Count the number of queens and jacks (overvalued honors).
Step 4: Subtract the smaller number from the larger number.
Step 5: Evaluate the difference:
If between 0-2, make no adjustment If within the range 3-5, adjust by 1 point If 6+ (rare), adjust by 2 points Step 6: If the number of aces and 10s is more, add; If the number of queens and jacks is more, subtract
We next apply the method to a few examples.
Hand 1 Hand 2 Hand 3 Hand 4 Hand 5
[A]AKQ105 [A]AK9 [A]A67 [A]A104 [A]K78
[B]10982 [B]KJ3 [B]KQ54 [B]10543 [B]AQ9852
[C]6 [C]J105 [C]Q7 [C]KJ67 [C]A109
[D]J67 [D]5678 [D]J678 [D]K10 [D]A
Hand 1: 10 HCP
3 (undervalued) 10A10; 2 (overvalued) honors QJ
3-2=1; no adjustment
The adjusted total for the hand is 10
Hand 2: 12 HCP
3 aces and 10s (undervalued); 2 Js (overvalued)
3-2= 1 no adjustment, but skewed in undervalued honors
The adjusted total for the hand is 12
Hand 3: 12 HCP
3 queens and jacks (overvalued); 1 ace (undervalued)
3-1=2 no adjustment, but skewed in overvalued honors
The adjusted total for the hand is 12
Hand 4: 11 HCP
4 undervalued honors; 1 overvalued honor
4-1=3; add 1 HCP; more overvalued honors
The adjusted total for the hand is 12
Hand 5: 17 HCP
4 undervalued honors; 1 overvalued honor
4-1=3; add 1 HCP; more undervalued honors
The adjusted total for the hand is 18
Using the Adjust-3 method of hand evaluation, one may consider opening hands two- five. However, is there more to the story? Yes. Clearly, if a suit includes AKxxx and another suit contains Axxx, one may take two tricks with the first and only one with the second. Thus, in addition to HCP, one must consider suit length.
After the Adjust-3 process, you must apply the following rule to modify your points for suit length; provided the suit contains at least one honor card: A/K/Q/J/10.
ADD FOR SUIT LENGTH
1 additional point for a 5-card suit
2 additional points for a 6-card suit
3 additional points for a 7-card suit, etc.
In summary, add one additional point for each card in a suit over four that contains an honor.
However, in addition to suit length, one has to consider dubious honors since they are OVER VALUED.
Subtract ONE point for hands with the following doubletons or singleton honors
DOUBLETONS: AJ, KQ, KJ, QJ, Qx, Jx (Quick tricks = 1, ½, or 0) SINGLETONS: K, Q, J (½ or 0 Quick tricks) Note that AK, AQ, Ax, and Kx are excluded honor doubletons.
Lastly, you must adjust for QUALITY SUITS - a suit with 3+ of the top five honor cards.
ADD ONE ADDITIONAL POINT FOR EACH QUALITY SUIT.
In summary, one proceeds through the following steps to obtain the total value of a hand.
Step 1: HCP
Step 2: Adjust-3 (add or subtract)
Step 3: Suit Length (add for length)
Step 4: Dubious Honors (subtract)
Step 5: Suit Quality (add)
Step 6: Total Starting Points
Completing steps 1-4, one has what Mr. Bergen calls "Starting Points." To open the bidding in the game of bridge (one of a suit), a hand is opened if it has at least twelve Starting Points in the first seat. There is more to a hand than simply high card points (HCP).
One final comment, in a suit contract, if your shape is 4-3-3-3, 5-3-3-2, or 6-3-2-2, or 7-2-2-2, you should downgrade your hand by one point for "flatness."
If the shape is 4-3-3-3 and one is considering a notrump bid, also subtract one from the total Starting Points.
Returning to Hands 1-5, we apply the process outlined above.

Counting only HCP, one would have opened hands 2, 3, and 5; however, using Bergen's method, one only opens hands 1 and 5. Also observe that the hands have at least TWO QUICK TRICKS.
BASIC RULE: Open a bridge hand one of a suit with at least 12-21 Starting Points and two quick tricks (in the first or second seat). The rule is relaxed in the third seat, more on this later.
The first step at the bridge table is that all players evaluate their hands; the process begins by the person designated DEALER. The person with twelve Starting Points opens the auction by bidding (there are exceptions called pre-emptive bids and strong two-level bids to be discussed later). As the auction progresses, the value of your hand may increase or decrease depending upon what you learn from your partner and your opponents. To keep the process simple at this juncture, suppose one person has a sufficient number of "starter points" to open a hand one of a suit with no interference.
Some players will open a hand with only 11 starter points (seats one and two). This is a modern day practice since it is important to get your bid in as soon as possible. However, one should have 2 quick tricks and a 5-card suit. Never open a balanced 11 point hand.
Another facet of the game one must consider when bidding is vulnerability. In general, there are four situations. The two pairs are non-vulnerable, two pairs are vulnerable, one pair is vulnerable, and the other pair is non-vulnerable. The value of tricks (won or lost) depends upon the vulnerability of your pair. More on this later!
Opening Notrump Bids
Having sufficient Starting Points to open, the first goal is to describe your hand to your partner. When you open, you may have a balanced hand, an unbalanced hand, or a semi-balanced hand. A hand with a singleton or a void is by definition unbalanced (35.7%). The patterns that do not contain a singleton or a void are 4-4-3-2, 5-3-3-2, and 4-3-3-3 (47.6%) and are called balanced hands; semi-balanced hands are hands with the following patterns: 5-4-2-2, 6-3-2-2, and 7-2-2-2 (16.7%). A frequency table of hand patterns follows.
When you open the bidding, you first want to communicate to you partner whether you have a balanced or non-balanced (unbalanced or semi-balanced) hand. However, if the semi-balanced hand has honor cards (AKQJ) in two of its doubletons, it may be considered balanced. When hands are balanced, one usually opens the hand with an opening notrump (NT) bid. Because roughly 50 percent of the hands dealt are balanced, many hands are opened using the notrump bidding scheme. In addition, it is used to describe rebids by an opener when bidding one of a suit. When bidding notrump you are saying to your partner, I have a balanced hand; suit bids often convey non-balanced hands.
Playing bridge the 2/1 way, the notrump ranges for NT bids and rebids follow.
Opening Notrump Bids Opener Notrump Rebids
1NT = 14/15-17 starter points 1NT = 12-14 starter points
2NT = 20-21 starter points 2NT = 18-19 starter points
Opener may make an artificial and forcing opening bid of two clubs and then rebid notrump with 22-24 Starting Points; more on this in Chapter 4. Interference is common over 1NT openings; bidding strategies are discussed in Chapter 9.
While some will open 3NT with 25-27 Starting Points, this will not be the case in this book. We will use the Gambling 3NT bid. Playing 2/1 the Gambling 3NT bid shows a solid seven-card suit and denies holding an ace or a king (in the third or fourth seat it may include an outside ace honor); more on opening 2[D] and 3NT in Chapter 4.
An opening bid of 1NT usually shows stoppers in at least three suits where a minimum stopper is defined as Qxx. However, never open 1NT with Jxx or less (xx) in a major.
When opening 2NT, you should have all suits stopped; however, some may open it with an honor doubleton, hoping his partner has the suit stopped. To reach game in a notrump contract, the bid is 3NT (for example, the bidding sequence may be simply 1NT-2NT-3NT), both hands combined usually require twenty-six Starting Points; however, with long suits and points balanced between the two hands, only twenty-four Starting Points may work. To make a game in notrump, you must take a minimum of NINE TRICKS out of thirteen.
If you take twelve tricks (the bid is 6NT), you have made what is known as a slam. To make a (small) slam usually requires 33 Starting Points in the two hands. And, if you take all thirteen tricks (the bid is 7NT), you have taken all of the tricks, a grand slam; to make a grand slam normally requires approximately 37 Starting Points. The goal of a partnership when bidding is to determine whether or not one has enough points for a partial notrump contract, a game notrump contract, a small, or grand slam contract.
Let's apply our methodology (yes, it applies when opening a major or notrump).
Step 1: HCP
Step 2: Adjust-3
Step 3: Add for suit length
Step 4: Subtract for dubious honor doubletons/singletons
Step 5: Add for suit quality
Step 6: Total Starting Points
A few more examples:
Example N1 Example N2 Example N3 Example N4
[A]KJ [A]KJ6 [A]K9 [A]98 [B]AQ4 [B]A104 [B]AQ5 [B]AKJ2 [C]A108 [C]AQ8 [C]K8 [C]102 [D]Q10854 [D]AK96 [D]K109874 [D]AKJ42
Example N1
Step 1: 16HCP
Step 2: [Undervalued Honors = 4 – Overvalued Honors = 3] = 1; no adjustment
Step 3: Add 1 for suit length
Step 4: Subtract 1 for dubious doubleton
Step 5: Add 0 for suit quality
Step 6: Total: 16 Starting Points
Open the bidding 1NT (balanced 5-3-3-2)
Example N2
Step 1: 21 HCP
Step 2: [Undervalued Honors = 4 – Overvalued Honors = 3] = 1; no adjustment
Step 3: Add 0 for suit length
Step 4: No dubious doubletons
Step 5: Add 0 for suit quality
Step 6: Flatness -1
Step 7: Total: 20 Starting Points
Open the bidding 2NT (balanced 4-3-3-3) Example N3
Step 1: 15 HCP
Step 2: [Undervalued Honors = 2 – Overvalued Honors = 1] = 1; no adjustment
Step 3: Add 2 for suit length
Step 4: No dubious doubletons
Step 5: Add 0 for suit quality
Step 6: Total: 17 Starting Points
Open the bidding 1NT (semi-balanced 6-3-2-2) Example N4
Step 1: 16 HCP
Step 2: [Undervalued Honors = 3 – Overvalued Honors = 2] = 1; no adjustment
Step 3: Add 1 for suit length
Step 4: Subtract 0 for dubious doubletons
Step 5: Add 2 for suit quality (hearts and clubs)
Step 6: Total: 19 Starting Points
With nineteen Starting Points, you should not open the bidding 1NT (if partner is a passed hand; some may open 1NT with eighteen starting point in the fourth seat). With twenty points, you would not open the hand 2NT when holding two worthless doubletons and good suits. You must open the bidding one of a suit.
Before discussing suit bids, one needs to understand what it means to "take tricks" in notrump. To set our ideas, suppose you open 1NT and all other players at the table pass.
You have won the contract (1NT), and to succeed, you must take seven tricks. The first six tricks are called your book; hence to make a 1NT contract you must take book plus one trick. Similarly, for a contract of 3NT, you must take book plus three tricks or nine tricks.
To capture tricks in notrump, each card in a suit is of decreasing value from the ace down to the 2 (A K Q J 10 9 8 7 6 5 4 3 2). However, the values are only meaningful for the suit led. If you lead, for example a club, only clubs are played and four cards constitute a trick. The highest valued card in the club suit is the [D]A. When you are unable to follow suit, you may discard any card in your hand; however, if you get in the lead later, you must be careful when discarding. One generally discards cards in other suits with low value.
Because there are no trumps in "notrump contracts," they are the most difficult contracts to make. Tricks are only won with a suit led. To establish tricks in notrump, you want to take advantage of long suits since these are the source of tricks.
Let's look at an example. You have the following hand: [A]KQ [B]A10 [C]AKQ10753 [D]KQ
and your contract is 3NT. In this hand, you have one spade trick, one heart trick, seven diamond tricks, and one club trick or ten tricks (ten potential tricks without a heart lead); hence, you may make 4NT. Bidding only 3NT you can make your contract plus an overtrick. In duplicate bridge, 3NT is worth 400 points if your side is non-vulnerable and 600 points if your side is vulnerable. Each overtrick is worth a score of thirty so that you have made either 430 or 630 points for the contract.
If you fail to make your contract, the value of a trick lost depends on vulnerability. Fifty points if you lose a trick non-vulnerable and 100 points if you lose a trick vulnerable. And, if the opponents do not think you can make a contract, it may be doubled. This doubles the values of the tricks lost. Hence, when bidding a partial (1NT = score of 90 or 2NT = score of 120) game or slam contract, one must consider the "risk" of not making the contract. Conversely, if you make a doubled contract, it also has a higher value when doubled and made. And, a contract may be re-doubled; even more points if made. When bidding, you must consider vulnerability.
