Chess piece relative value

Bauer units are mainly used chess programs and chess players, as the basis for positional evaluation and for estimating the consequences of a train. As the basis of this unit, the value of a farmer equal to 1 has been set.

The individual figures then have the following values ​​that count most chess players:

However, modern chess programs expect more accurate values ​​that are multiplied for faster calculation of hundreds. For example:

However, there are also positions in which some characters are not particularly active, then the computer draws a bit of the value. A most accurate calibration of these items, mostly on the basis of results in test position, is one of the important tasks of a chess programmer.

From the figures given it follows that with unequal material conditions, usually as 2 towers are stronger than a lady or two minor pieces ( Bishops and Knights ) is generally stronger than one tower. The king has no value in pawn units, as with his loss and the end of the game would go hand in hand. Thus, of course, everything must be done to to prevent checkmate.

In chess, sport there is in this respect also the concept of "quality". One speaks of a " quality win " if you can trade a minor piece ( bishop or knight ) against a tower, according to a " quality loss " in the reverse case.

All these values ​​are, however, only be understood as a rule of thumb. It also depends on the position. It may well be useful to sacrifice a higher figure for a character with a lower value, if you achieved a position of advantage. For example, the possession of the bishop pair compared to two jumpers or jumper and a runner has higher priority, whereas a single Springer may be superior to a single runner. Computer chess programs consider the position in their calculations, thus changing the individual values ​​according to Bauer units. In this way, the programs can opt for the best possible train and also notice how the value of the position of the two players would change for a train.
