drukenknight: for all you theorists out there who disagree on how to count isolated pawns. look at this game.move 48 spassky is ahead by connected pawns only and he seeks to exchange.
move 50. Larsen still behind in connected pawns looks to check the K. He keeps doing it.
move 56. black has stopped attacking (going for the pin instead) so white looks to attack.
move 57, black sees that white has repositioned so he goes back to attacking, except now something has happened and it doesnt seem to work.
move 59 now white is attacking but he is ahead in material. black blocks w/ Q. Why doesnt white exchange Qs? Because it's not an equal exchange, black will reconnect the pawns and the game will be equal.
Okay so what did Larsen do wrong? THis is not too hard, you dont have to see 10 moves in advance.
