zealouspawn: Brett-- I'm with you on thinking this is exactly what he had in mind when he gave up the DSB.
I love the peice-decisions black makes in the game from move 28 onward:
1) trading the bishop pair in consecutive moves to get the superior minor peice endgame
2) working to trade off the rooks so that the knight vs bishop advantage is magnified
3) avoiding a queen trade on move 40 that would change the pawn structure to give white a passed pawn AND give white's bishop more breathing room
**notice black doesn't work to get the queens off, it is widely regarded that Q+N vs Q+B endgames are often advantagous to the Q+N player as Queens and Knights coordinate together well.
4) Only AFTER white sacrifices a pawn to make his bishop better does black allow his knight to be traded for the bishop on move 57.
**This is now an acceptable trade because he has transfered advantages: he loses his minor peice advantage but gains a pawn and has a more centralized queen
Very instructive play!
