Christiansen sacrificed a rook for two pawns here, with Rxe6!?
[D]r3k2r/pp1n1pbp/2p1p1p1/1q6/3P4/1QP2N1P/PP3PP1/R1B1R1K1 w kq - 2 14
He went on to win the game (see PGN below), but is this sac really sound?
You'll probably want to skip ahead a few moves and start from this position:
[D]r1k4r/pp1n2bp/2p1Q1p1/1q4B1/3P4/2P2N1P/PP3PP1/R5K1 w - - 2 17
Christiansen played Re1 here, which Chess Tiger thinks is losing for White (-2
pawns or so). Instead, Tiger prefers Qf7, and sees a lot of compensation for
White, but not enough to justify the sacrifice. For example: 1. Qf7 Bf6 2. Bxf6
Qf5 3. Ne5 Nxf6 4. g4 Nxg4 5. hxg4 Qxf7 6. Nxf7 Rf8 7. Re1 Kd7 8. Ne5+ Kd6 and
White has a pawn for the exchange but is probably losing.
Crunch this one for a while and tell me if you find differently.
