    Rxb2Ch! wins

    – Kxb2, Qxc3ch, Ka3, Qa5ch, Qa4, Qc5ch, Qb4, Bb2ch, Ka4, b5ch, Ka5, Bc3ch, Ka6, Qb6 mate. (If Qxb5 instead of Ka5 then Qa3 mate.)

    – Ka1, Rxb3!, Qxc7, Bc3ch, Qxc3, Rxc3 with winning endgame.

    Well, I saw Rb2 almost immediately, though I did have to put some thought into what comes after that to get black an edge.

    1. …..Rb2
    2. Kb2 Qc3
    3. Ka3 Qa5
    4. Qa4

    Mate will follow 4.Ba4: [4.Ba4?? Qc5 5.Kb3 Qc3#]. Continuing:

    4. …..Qc5!
    5. Qb4 Bb2!
    6. Kb2

    And mate will also follow 6.Ka4: [6.Ka4 b5! 7.Ka5 (or 7.Qb5 Qa3#) 7. …Qb6#]. Continuing:

    6. …..Qb4 and black has a decisive edge, though not always an easy win.

    And it does white no good to not take the rook at move 2:

    1. …..Rb2
    2. Ka1

    Or 2.Kc1 Qc3 will mate. Continuing:

    2. …..Qd7!
    3. Rd7 Bc3

    And black must wins something with the coming discovered check. The best I can see for white is…

    4. Bf7 Kf8
    5. Rc7

    Trying to hide the rook from the other rook…..

    5. …..Bf6 and now white must lose his rook.

    1…R:b2+ and it’s all over. 2. K:b2 Q:c3+ 3. Ka3 Qa5+ 4. Qa4 Qc5+ 5. Qb4 Bb2+ and now if 6. Ka4 b5+ and 7. Q:b5 isn’t possible because of …Qa3#. So White’s best is 6. K:b2 Q:b4 with a big material advantage and an attack.

  10. James I. Hymas Reply

    1… R:b2+
    2. Ka1 B:c3
    3. Q:c7 R:b3+
    4. Q:c3 R:c3

    and black has a very nice, if not won, ending.

    Finding the first move is easy, as there aren’t any good alternatives. But it takes a while to figure out till the end.

    1. … Rxb2+!!
    2. Kxb2 Qxc3+
    3. Ka3 Qa5+
    4. Ba4 Qc5+
    5. Kb3 Qc3+ checkmate

    If,
    4. Qa4 Qc5+
    5. Qb4 Bb2+
    6. Kxb2 Qxb4 0-1

    If,
    6. Ka4 b5+!
    7. Ka5 Qb6+ checkmate

    If,
    7. Qxb5 Qa3+ checkmate

    Now, the only other option White has at the beginning is:
    1. … Rxb2+!!
    2. Ka1! Qxd7
    3. Rxd7 Bxc3!
    4. Bxd7+ Kf8
    5. Rc7 Bf6
    6. a4 Rc2+ 0-1

    @Yancey:
    Amazing to see exactly the same lines given by both of us, just the presentation is a little different 🙂
