Black to move and win. How should black proceed?
Source: ChessToday.net
Was looking at 1…….Nc3.
But then saw 1…….Nf4!
The white queen is attacked.
The black queen is taboo.
The ‘e6’ square is also covered.
2. Qf7 (forced)
2……. Qxc5! This is cute.
0-1
Nf4 or Ne3. WHICH knight move should Black play?
One sees pretty quickly: 1. .. Ne3 2. dxe5? Rxd1# and 1. .. Nf4 2. dxe5? Ne2+ 3. Kb1 Rxd1#
It promises to become a labyrinth when considering the number of defenses White has after each of these initial knight moves.
After 1. .. Ne3, one has to consider 2. c3, 2. Re1, 2. Rd2, 2. Qf7, 2. Bf3, 2. Nxb7, and 2. Rd3
After 1. .. Nf4, one has to consider 2. Qf7, 2. Qe6+, 2. c3, 2. Be4, and 2. Ne4
The variations after 1. .. Ne3 quickly become complicated. White probably does best after 1. .. Ne3 to play 2. c3.
1. .. Ne3
2. c3 Qd6
(2. .. Qxc5 3. Qe6+ Kb8 4.Qxe3 Qd6)
3. Qf7
(3. Qxd6 Rxd6 4. Rd2 Rg8 is no good for White.)
3. .. Qxc5 4. Qe6+ Kb8 5. Qxe3 Qd6 and although Black has a big advantage, nothing much has been accomplished from the starting position.
It’s a lot easier to calculate the variations after 1. .. Nf4, and things look very promising for Black after that move.
1. .. Nf4
2. c3? Qe3+ and Black wins the queen with no compensation for White.
1. .. Nf4
2. Qf7 (threatens mate with Qb7, which is foiled by) Qxc5 and Black is a rook up with no problems: 3. dxc5? Ne2+ 4. Kb1 Rxd1#
1. .. Nf4
2. Be4 or Ne4 (Either one of these White moves prevents Black from checking with Qe3+ next move, and then taking the White queen with the knight.) But now Black can continue:
2. ..Nxg6 3. dxe5 Rxd1+ 4. Kxd1 fxe4 leaving Black a rook up and no problems.
The last try for White is 2. Qe6+, and that also loses.
1. .. Nf4
2. Qe6+ Nxe6
3. dxe5 Rxd1+
4.Kxd1 Nxc5 and Black is again a rook up.
Nf4+
i dont need to explain this one.. its obvious.. am i supposed to find this problem difficult?
1. …. Ne3
2. Bxc6 Rxd4
3. Bxb7+ Kb8
4. Rxd4 Qxd4
5. Qg3+ f4
6. Qf3 Rd8
7. Na6+ Ka7
and white is out of checks.
8. c3 Qd2+
9. Kb1 Qc2+
10.Ka1 Rd1+
0-1
or
1. …. Ne3
2. Qf7 Qxc5!
0-1
My first reaction was 1…. Ne3 so that 2dxe5 is replied by 2… Rxd1#. However after 2 Bf3 every thing is protected.
1… Nf4
2Qf7
(The only place for Q.)
(2dxe5 is met with 2… Ne2+ Kb1 3Rxd1#)
(2c3 Qe3+ followed by 3… NxQ)
2…Qxc5
3c3
(3Qf6 Qf8 and Q exchange can not be avoided due to hanging state of white B.)
3… Qf8 and after Q exchange white has no scope.
4Qxf8 Rhxf8
Black queen can calmly stay were it is, I think.
1. Ne3! Rd2/Rd3/Qh5 (dxe5?? Rxd1#)
2. Rxd4!
Black up with material, queen perfectly safe, and so much now hangs on white side, it is going to be more.
I admit that 1. … Nf4 looks better than my suggestion 1. … Ne3.

Well, some of those moves may be something that I overlooked but perhaps not quite that many:
1. .. Ne3
2. c3? Qxc5!
3. dxc5?? Rxd1#
2. Re1 Qxd4
double threat Qxc5 and Qd2+ looks good for black
2. Qf7? Qxc5!
3. dxc5?? Rxd1#
2. Nxb7 Rxd4
actually threats 3. … Rxd1# black seems to have material gain.
What I probably considered too pourly was:
2. Bf3
2. Rd2
2. Rd3
