70 ( +1 | -1 ) Apparent blunder, possible noveltyIn my game versus aramis, the following line was played: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Nxe4 6.d4 b5 7.Bb3 d6 This is the move I'm referring to. After the obvious 8.Bd5 (I even made a snide remark at this point) the not so obvious 8...Qd7 seems to hold on to the piece in all variations, i.e. 9.Bxe4 d5 and if 10.Bd3 e4 with a potentially good game for Black. However, White can play 10.Bxd5 and turn this line into a gambit. Still, this may be playable as Black now has the Bishop pair and a potential attack against the castled White King. Also I feel I should mention that my opponent played 8...Bb7 and is now struggling to stay in the game with a piece for a pawn.
71 ( +1 | -1 ) Although this game is still running,the situation you described and the current position (13 moves later) are completely different. So I think it is okay to comment on it:
Playing White I would not play Bxe4 immediately because this black knight is lost anyway: If it stays on e4 White will capture it (later) with the bishop. If it tries to escape Black has given up his control of g5, so that the white knight f3 has a perfect square with a beautiful look to f7. 9. dxe4 should cause much more trouble for Black than your proposed 9. Bxe4 because now there is no way to re-win the white piece with the pawns on the d- and e-file. Black seems to face the choice between pestilence (one piece down) and cholera (f7-problems).
