The book you have just started reading is about a very interesting and difficult concept: the exchange sacrifice. This is the moment in chess when basic mathematics breaks down, the moment when 3 counts equal to or even more than 5. So let us leave the mathematics aside and try to figure out why this simple calculation is so difficult to understand. The answer is largely hidden in psychology, as the ninth World Champion, Tigran Petrosian, has often told us, as the man who brought this strategic-tactical chess concept to its first peak. Chess beginners were taught the value of pieces by their teachers (parents, grandparents, perhaps at school or even later in the beginners’ sections of chess clubs). We explain the difference between piece values to children in the simplest way possible, with the help of a unit of measurement, and in chess those units are the pawns. They tell us that a rook is worth five pawns (units) and a knight and a bishop are worth about three each. They also tell us to always be careful, especially during exchanges, to ensure we take at least as much from our opponent as he or she took from us. So, one rook at a time, perhaps for a bishop and a knight next to two pawns. This “chess thinking” is done quickly and very strongly subconsciously in most, one could even say all. Therefore, when choosing moves, we will automatically reject unfavorable exchanges. But who trades a queen for a knight, a bishop for a pawn, and the like? We know from our own life experience that it is better to have ten coins in our pocket than three, and I prefer three to one! This psychological barrier is the most difficult step in making the decision to sacrifice. And so it is with the sacrifice of an exchange. Five for three, that is! Even five for four, if we get a pawn for the rook along with the knight or the bishop. “I am not stupid,” you think. The Exchange Sacrifice Unleashed brings different games or coaches try to explain this and that to us, we see that a material advantage is not always something to celebrate about.

Instructions for revocation

Right of withdrawal for the sale of goods

Revocation right for consumers
(A ‘consumer' is any natural person who concludes a legal transaction which, to an overwhelming extent, cannot be attributed to either his commercial or independent professional activities.)

Instructions for revocation

Revocation right
You have the right to revoke this contract within 14 days without specifying any reasons.
The revocation period is 14 days with effect from the day,

on which you or a third party nominated by you, which is not the carrier, had taken possession of the products, provided you had ordered one or more products within the scope of a standard order and this/these product/products is/are delivered uniformly;
on which you or a third party nominated by you, which is not the carrier, had taken possession of the last product, provided you had ordered several products within the scope of a standard order and these products are delivered separately;
on which you or a third party nominated by you, which is not the carrier, had taken possession of the last part delivery or the last unit, provided you had ordered a product, which is delivered in several part deliveries or units;

To exercise your right of withdrawal, you must inform us (preigu GmbH & Co. KG, Lengericher Landstr. 19, 49078 Osnabrück, Telephone number: +49 (0) 541 / 580 72 84, E-Mail address: mail@preigu.de) by means of a clear declaration (e.g. a letter sent by post, or an e-mail) of your decision to withdraw from this contract. You can use the attached model withdrawal form for this purpose, which is, however, not mandatory.

You can also exercise your right of withdrawal online by clicking on a button labelled accordingly (such as ‘Withdraw from contract' or similar) on the AbeBooks/ZVAB website. If you use this online function, you will immediately receive a confirmation of receipt on a durable medium (e.g. via email) containing information on the content of the withdrawal notice, as well as the date and time of its receipt.

In order to safeguard the revocation period, it is sufficient that you send the notification about the exercise of the revocation right before the expiry of the revocation period.

Consequences of the revocation

If you revoke this contract, we shall repay all the payments, which we received from you, including the delivery costs (with the exception of additional costs, which arise from that fact that you selected a form of delivery other than the most reasonable standard delivery offered by us), immediately and at the latest within 14 days from the day on which we received the notification about the revocation of this contract from you. We use the same means of payment, which you had originally used during the original transaction, for this repayment unless expressly agreed otherwise with you; you will not be charged any fees owing to this repayment.

We can refuse the repayment until the products are returned to us or until you have furnished evidence that you have sent the products back to us, depending on whichever is earlier.

You must return or transfer the products to us immediately and, in any case, at the latest within 14 days with effect from the day on which you inform us of the revocation of this contract. The deadline is maintained if you send the products before the expiry of the 14 day deadline.

You bear the direct costs for returning the products.

You must pay for any depreciation of the products only if this depreciation can be attributed to any handling with you that was not necessary for checking the condition, features and functionality of the products.

Criteria for exclusion or expiry

The revocation right is not available for contracts

for delivery of products, which are not prefabricated and for whose manufacturing an individual selection or stipulation by the consumer is important or which are clearly tailored to the personal requirements of the consumer;
for delivery of products, which can spoil quickly or whose use-by date would be exceeded quickly;
for delivery of alcoholic drinks, whose price was agreed at the time of concluding the contract, which however can be delivered 30 days after the conclusion of the contract at the earliest and whose current value depends on the fluctuations in the market, on which the entrepreneur has no influence;
