Subject: Comment from Kasparov about deep tactical position

Author: K. Burcham

I think this is the game Kasparov is refering to.
maybe this is the combination he had to study?
Had to modify King safety to get shredder 7.04 to play 16. Bxa6.

"One combination, I think it was a game Fritz lost to Shredder in a Sveshnikov,
it took me a while to see what was going on! It was some incredible tactics!
Kasparov
