More ANTI-GM examples
Anand - Leko 18.c5! Wijk aan Zee 1996
Rebel 10.0 (normal) the pawn sacrifice isn't found after 15 minutes.
Rebel 10.0 (anti-GM) 18.c5! found after 85 seconds.
Deep Blue - Kasparov the re-match of 1997 won by Deep Blue.
In this famous position Gary Kasparov resigned while he could have a draw with Qe3! Like Gary for most computers this move is also very hard to find.
Rebel 10.0 (normal) Qe3! not found after 13 plies and 30 minutes.
Rebel 10.0 (anti-GM) Qe3 found at ply 12 at 7:22
Hiarcs - Genius Bxh6! WCM 1993 Munich
Rebel 10.0 (normal) Bxh6 found at ply-7 in 0:29
Rebel 10.0 (anti-GM) Bxh6 already found at ply-5 in 0:01
Jongsma - Rebel 1..d3!? AEGON Man vs Machine 1990
While Rebel already in 1990 played this aggressive move these days Rebel eventually will play the more normal Nf6 developping its pieces. Rebel 10.0 + anti-GM will definitely play 1..d3!? and stick to that.
This behavior is very typical for Rebel10 using anti-GM and this example is perhaps the best one from the given examples to explain about anti-GM.
The general chess rule is to develop ones pieces first before you launch an attack so in this respect the move 1..d3!? looks a bad choice. However because of 1..d3!? 2.cxd3 Nc5 black will (temporarily) get the knight on d3 which will block white's development.
Which move is better? The quiet, more normal 1..Nf6 or the aggressive 1..d3!?
We do not know the answer to that as both moves look good and it is more a matter of taste but one thing is for sure, grandmasters playing against a computer will not like 1..d3!? at all because it will give them a hard time. Bottem line: anti-GM mission accomplished!
