    Nice! Black suffers of a tough "zugzwangitis"!

    Interesting puzzle, though the moves are pretty forced on black's account.

    It's really not that hard. But it does have a nice logic to it.

    I don't know all that much, ut what about:
    1 ... Qxe4

    That seems like a good move for black to me:

    1. Queen isn't under attack
    2. King isn't under attack
    3. Knight on a7 guards against 2 Bb5
    4. Queen guards against 2 Kb4

    Plus, with 2 ... Qxf4 (assuming blacck doesn't play 2 Ng6) black would be up 7pts

    He could win with:

    1 ... Qxe4
    2 Ng6 Qd4
    3 h7 Qxf4
    4 h8-Q+ Kg5
    5 Qa8 Qc4+
    6 kb2 Qd4+
    7 Kb1 Kh5
    8 Qc8 Kxg6
    9 Bf5+ Kh6
    10 Qe6+ fxe6
    (white no longer has the peices to win)
    11 Bxe6 b3
    12 Bf5 b2
    13 Ka2 Qf4
    14 Bd3 Qe3
    15 Bc2 Qd2
    16 Bb1 Qc1
    (this would probably go on until a 50-move draw)

    It's white to move first.

    Solution:
    1.Re3! Black has difficulty watching both the g8 and d5 squares. If he loses control of either, White has an N mate waiting. 1...Qg2 The only move. 2.Bg4! Cuts off the Q from g8, and takes advantage of a selfblock after 2...Qxg4? 3.Nd5+ Kf5 4.Re5#. 2...Qa8 3.Re5! The Bishop holds f3, and the Rook covers f5 in case Black decoys the wB away. 3...Qd8 4.Bd7! Qa8 5.Re4!! And White has restored the diagram position, but with Black to move. Black can no longer hold both the g8 and d5 squares, and will be mated next move.
