    e6+ followed by BxQ leads to checkmate for black with the bish & rook. I dont see any knockout blows... but after Qxh5 white K-side pawns seem unstoppable

    Hmm...how do you post that hover icon with the answer?
    It's pretty useful as a non-spoiler.

    Anyway, since I cannot find it I ll just write it normally.

    Indeed. Sometimes the strongest move is not to knockout yourself.

    The correct move is f3 which either wins the bishop or dislodges the bishop and wins the Queen

    Yeah.. i'd like to know too how you post that icon.. seems pretty cool 🙂

    @Anthem
    I do not see how BxQ can lead to a checkmate for Black with bishop and rook. After black's BxB, if white moves c3 the checkmate is not imminent or even not a possibility.

    @vzo
    I do not think black's losing queen has anything to do with troubling the bishop or the f3 move. Moreover, if black moves Bg6, white's Qxh5 is a distant possibility. The only way the black's queen can be captured is by the e6+ move. To me this is the best move at this point.

    smartarin - The c-pawn is pinned to the king by the light sq. bish

    vzografos - I still don't see it. If the bishop retreats to g6, then does it not still pin the c-pawn?

    Hi guys I ll give you the full lines later today.

    But e4+ followed by queen capture is definitely mate for black

    Ok so first of all this exercise was designed to show that sometimes a seemingly strong move (i.e. e6+ followed by discovered attack on the queen and taking the queen) although it seems VERY appealing can be a blunder.

    So the mate line is:

    e6+ Kxe6
    Bxg7 Bxg7
    Irrelevant move by white but say Qa6 Rxa6
    Irrelevant move by white (say b4) Ra1#


    Now, if white plays f3 and say bishop retreats to g6

    f3 Bg6
    e6+ Kxe6
    Qb5 (threatens to fork King and rook) Kf7
    and then, either the rook will have to leave the a-file which means the queen is gone or move between a5 and a8 which means the black pawns are gone with an eventual
    Qc6 Ra5
    Qxb6 Ra8
    Qc6 Ra5
    Qxd5+ e6
    Qb7+ and the black queen is gone

    So for black it is best to sacrifice the Bishop after
    f3 Bxc2+
    Kxc2 and moves the blac queen out of harms way with a check

    or
    f3 Bf5
    e4 (black moves queen out of the way but loses bishop)


    So in conclusion, the stronger move for white, (assuming perfect play from black) is to win the bishop. After that of course the game is even easier for white.


    Anyway, so that was a first attempt at an chess puzzle. I guess it was a bit out of the ordinary (mate in n moves or find the ! move). Of course white could play many ok moves (since he was in better position) and eventually win, but the best one to win material is the short run is f3.


    I'll try again with a more conventional puzzle in the future 🙂

    What if black plays Kg8 instead of Kxe6?

    This loses material faster for black

    f3 Bg6
    e6+ Kg8
    g4 and the queen, king and bishop are on the same file. They cannot be defended.

    Doesn't 1.e6+ Kxe6 2.Qb5 work too? The threat of Qc6+ wins easily.

    Also, if he did not have Q-e2, he could just take the queen, king takes and then f3 gets the bishop anyway. That also eliminates the possibility of the bishop taking at c2+ which of course doesn't work in this position but is a possible way out in others.
    When the bishop is pinned by the rook he can't even move it to take on c2.

    ...and gets mated by ...Ra1 one or two moves later.

    Who says you have to take the queen? You're already a rook up. Consolidating your advantage seems a better idea.
