In game 2, Kasparov thought that there was human interference with this line.
He requested the logs to see for himself that these two moves were actually in
the Deep Blue eval.
Kasparov did not think any program would play 36.axb5 avoiding 36.Qb6 or the
move 37.Be4.
But it seems that todays programs will accomplish what Deep Blue was trying to
do in the game.
Deep Blue opened up the a file and blocked Kasparov's play with 37.Be4, limiting
blacks mobility.
Below in the examples you will see that two of todays strongest programs will
also accomplish this same objective. Both Fritz7 and Chess Tiger 14.0 will open
the a file and control the a file. also both Fritz7 and Chess Tiger 14.0 will
play Be4 limiting Kasparov's mobility with black.
All three programs, Deep Blue, Chess Tiger 14.0 and Fritz7 put the
squeeze on black, blocked with the Be4 move, opened the a file, threatened to
capture blacks bishop, forced black to protect the loss of pawns, etc.
I started each program after Kasparov's move 35...Bxd6.
after each program analyzed for several hours, I took the line from each
program and played it through to the position after blacks move 40.
This way we can cover both controversial moves.
