Sally Simpson: The game up to move 21 followed A Borstnik vs L Quaresma, 2008 here
click for larger viewMax instead of moving the f8 Rook played 21...f5. (the linked game was drawn but White managed to get an attack going. Even when the Queens off. Black was a piece down at the end.) ---
Hi User not found,
" I don't understand the idea behind saccing the a and b pawns..." White also threw in the e-pawn. Your computer is not showing all the ways to go wrong in this variation. And better players than me and you have stumbled grabbing the theoretically safe a & b pawns. Black is far behind in development and has an exposed Queen on an open board nicking pawns. You have to have complete faith in your ability (and your seconds..and their computers) to venture into this these days. You also have to thank the many poor souls before you who were torn to shreds as Black trying to keep this opening alive. This game follows most of the thread game where White won. M Pacher vs R S Kalugampitiya, 2010 It hints that Black followed his book theory and then, like it always has to at some stage, he ran out pages to recall. BANG! ---
Hi Conrad,
Good line. With three pawns in the bag a Queen sac for two minor pieces may just be OK. There it looks just fine. Fischer tried a Queen sac against Spassky in a relatively unknown game in '72 in this line, it did not come out too well....(a joke). |

sac: 21...f5
