Be7, castle, castle, Nb3, takes, takes, d5, takes, takes. Now black's structure is actually weak. He has double pawns on the c-file and isolated pawn on a-file. Let's see how white attacks them. This is typical move. Rook can be transferred to the kingside as well as on the c-file to attack weaknesses there. Bf5, Bd3, trying to exchange a bishop and then c6 pawn is going to be even weaker. Takes, takes, Qf6, g3, Rf2e8, Kg2, Bc5, Rf4, Qe6, Rd1. White is threatening to invade on the 7th rank. Bd6, Rc4, attacking the weakness, c5, Qf3, Ra2b8, Bd2, f6, Ra1, again attacking the weakness, Rbd8. This threatens, takes, and then takes the bishop. That's why white plays Be3, Qe5, Rc3, protecting the pawn, Ra8, protecting the pawn as well, Ra5. Now triple attack on the weak pawn and pawn cannot longer be protected. Qe4, takes, takes, takes, Be5, Re3, takes, and now nice tactic, takes, takes, takes, takes, takes, Kf7, Kd3. Later in the game, white created a passed pawn on the queenside and won the game.
