Potter, John Russell - GM Benjamin, Joel

[darkstarr]

I have greedily pasted the game below, PGN-compatible.
GM Benjamin played the so-severely called Two Knights Tango here. I`m curious as to what some strong players think of this. Of cuorse, I can easily run Fritz 8 on it, but I don`t always trust its assessaments of wildly opening positions. It does, however, claim that White is winning after 17.Qxc5. GM Benjamin said himself during the postmortem that he thought his pawn sacrifice was unnecessary and duboius.
Would anyone care to look at this game?

Haven't looked at this game, but the Black Knights Tango is a pretty playable defense. Black's biggest problems come after 1.d4
Nf6 2.c4 Nc6 3.Nf3 e6 4.a3 (as playewd by Kasparov vs. Yermolinsky once); black either plays ... d5, with a QGD where the Nc6 looks funny, or .. d6, with an Old Indian or Kin's Indian where his pawn gets to e5 in 2 moves instead of one. (Maybe white's extra motion of a3 aint wich useful.).
