Here I instantly looked at:1. Nb6!? Qe6??2. Rge1gaining queen.But this goes:1. ... Qc7! (only piece saving move)Here I must choose between:A) 2. Bd5 Bxc2+ 3. Qxc2 Qxb6 4. Bxf7+ Kxf7 5. Qxa4 g5/Ng6up with only quality for pawn.B) 2. Qxf5 Qxb6 3. Bd5seemingly with the same result.The gain of quality is a small improvement for white, but not much.I think I need to find something better! Another possible idea was:1. Rge1Here I find neither Q moves nor K moves convenient for black to avoid the fork Ne7+, also gaining quality for white. But 1. ... Be6! looks good for black.
Clearly tempting is the lineup of the Rook(f7) and King which look ripe for a pin B(g2-d5). I think the problem in solving this is that there are such tempting things to do with the Knight to clear the d5 square for the Bishop. There looks like a possible fork at e7 and then there's Nxf6 because of the latent pin on the g-pawn. But of course the problem is both these squares are covered by the Rook which would take it off the diagonal and escape the pin. Is there some deeper tactical resource involving either of these two Knight moves? I don't see one but there is another threatening Knight move to gain time for the pin on d5.1. Nb6 Qe62. Bd5 Qxb63. Bxf7+ Kxf74. Qxf5 .... and White has won the exchangeanother variation:1. Nb6 Qc7 giving up protection of the B but planning to take the Knight in exchange, while not adding the Queen to the trainwreck on the diagonal. But it doesn't stop the pin2. Qxf5 Qxb63. Bd5 ... the presence now of the Queen on f5 means that Black's interposition of the Knight to e6 would be useless. Again White wins the exchange.- Craigaroo
Nb6 occurs to me instantly to divert the queen from protecting the bishop on f5. Moving the queen to attack the knight won't work since the exchange of pieces allows white to pin the rook and win the exchange at f7:1. Nb6 Qc7Nothing really better here. If black plays Qe6, white just plays Bd5 immediately. Black can exchange the bishop for the pawn (with or without liquidating the queens) at c2, but that is marginally worse on a material basis than the line that follows:2. Qf5! Qb6 (what else?)3. Bd5 and black must lose a rook for a bishop.
1 Nb6 threatens to deflect the defender of the Bf5. 1...Qe6 2. Bd5 Qe5 3. Rge1 and White will win a whole R.1...Qc7 2. Q:f5 Q:b6 3. Bd5 wins an exchange1...B:c2+ and white wins a piece for a pawn.After all of these lines, white has a considerably more active position.
difficult but i saw this in 5 mins.. 1. Be4 Bxe4 2. Nxf6+ Rxf6 3. Qxf6 Qc7 Dunno if i'm right. Lemme ask my computer
