Materialism in Chess Engines Empty Materialism in Chess Engines

The TCEC Tournament -  - is a very interesting field for investigations of chess programs. Because the engines play without opening books and with long thinking times, excellent combinations are achieved.

However, the tournament also reveals major weaknesses in the programmes. Even after 20 years, for example, materialism is still a problem. In the past, you could win a whole game against the chess computers with a modest pawn sacrifice. Nowadays it is no longer so easy...
But also the newest programs still have their big deficit concerning materialism.
Materialism is, so to speak, a genetic defect...

Here are three typical examples:

DeusX 1.0 vs Bobcat 8
