As an exercise, try out the following position (Black to move
), with these questions in mind:
1. Is this a win for White or a draw?
2. What plan gives White the best chances?
3. What plan gives Black the best chances?
For those who want to see the game continuation check out Portisch-Petrosian 1974, 12th match game. I'll go over some ideas later on (before I do I'll comment on an unusual game at the club last night).
As a bonus question, what if the pawn is on a4 instead, with the rooks on the a-file?
