Yesterday evening, I was confronted with an annoying defense, I was confident I got it right, but found myself without any advantage.
1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 e6 6.Bg5 Bb4
Not the strongest black continuation in the Euwe
7.Bd3 h6 (diagram)
The analogy with the lines after 6...h6 forced me to exchange on f6 without any thought, as white gets a great attack on the f column.
8.Bdf6 Qxf6 9.0-0 Bxc3 10.bxc3
With a pawn ahead, black decides to exchange another piece.
"Life can be simple, even when faced with the complicated Blackmar Diemer gambit"... That's sort of blakc's thinking here. Another one could be "Show me what you have for the pawn".
11.Ne5 Qe7 (diagram)
I had been playing on automatic up till this point, under the impression that I would have a simple game. However, now I realised that things aren't that simple as I believed... I played 12.Qg4 in the above position and lost in the resulting endgame.
With silicon assistance, it seems 12.Qe2 is best here.
a/ 12...Nd7 13.Rf3 Nxe5 14.dxe5 (+=)
b/ 12...Nc6 13.Nxc6 bxc6 14.Rf5!!! (+=)
c/ 12...Bd7 13.Qg4!!!! (++)
So it seems that every annoying defense has some great refutation - but you have to find it !!
