I have been trying to solve the below chess puzzle for more than 2 days. Can someone help me to solve it?

White to play and mate in two moves

[FEN "n1N1Kn/2p/P1k/2p1Q/P/2P/7B/6Nq w - - 0 1"]

I have tried to do it, but my tries take more than two moves.

[FEN "n1N1Kn/2p/P1k/2p1Q/P/2P/7B/6Nq w - - 0 1"]

1. c4 Qf3 2.  Nxf3 Nb6 3. Ne7#

    BTW, white pawns are going top and black ones should go bottom. I am not much good in chess. so thought to make this a point. :) – Mr_Green Mar 31 '14 at 07:34

  • @Mr_Green it does seem that 1.Qe2 is correct... –  Mar 31 '14 at 10:57
  • @RauanSagit yes I got that now.. but how this worked? what is the danger to black king if I keep the white queen on Qe2? please explain.. – Mr_Green Mar 31 '14 at 11:00

    @Mr_Green Well, after 1.Qe2 black has to make a move. And any move that black makes will lose. The white queen on e2 allows Qe2-b5, Qe2-c4 as well as Qe2-e6 and control over g2, f3 and e4. The white queen has to control all these squares in order to deliver a checkmate in move two. –  Mar 31 '14 at 11:03
  • @Mr_Green, as @RauanSagit said, any move that black makes will lose. This kind of situations are called zugzwang – Kakadu Mar 31 '14 at 14:44
