    I understand that this is not the puzzle section, but bear with me.

    I saw this move on Josh Waitzkin's academy on CM-GM and it's the most gorgeous, counterintuitive move I've ever seen.

    White to play. Find white's best move.

    My every intuition screams Bd7, but I'm not sure why. Obviously, the bishop can't capture, but black doesn't seem to be doomed if the queen does... but that move has to be right, because it's the sort of freakish move that's ALWAYS right in that kind of puzzle. :-)

    Why I hate this game -

    This is just one more position that has me clueless.

    Bd7 is the right move.

    If ..Qxd7, Nxe6+!!

    Bd7 stuck out to me too but I didn't think it was working. Great puzzle though!

    Why is it so "counterintuitive"?
  7. 04 Aug '08 12:21
    I don't get it.
    1.Bd7,Qxd7 2.Nxe6+,Qxe6 3.Qxg7+,Ke8 then what? 4.Nxd5 is best I can see but is that supposed to be winning?Am I missing something?

    Why??? I honestly can't find a winning line for white if the bishop captures... Please tell me what I'm missing...

    Thanks for the explanation.

    What would happen if black just took white's queen with the knight? Wouldn't it come out even? Perhpas down one piece.

    Well, I guess it wasn't as hard as I thought, or the players on this board are just very good.

    The answer is Bd7; anything else allows black to end the attack.

    I though it was so counterintuitive because white's queen is hanging and the best move is to hang another piece on a square that it could be taken for free by any of 3 pieces.

    Waitzkin describes it as "throwing a rock in black's machinery." I love that description.

    Also, you're right that black is not "doomed" after that. After Nxh8, Nxe6+ leads to forced mate. After Bxd7, Qxg7 leads to mate or big material loss for black. Rxd7 leads to Nxe6+ and loss of queen or mate for black.

    After Qxd7, black survives, but after a long variation, white still has a nice attack. I forget the variation off hand- I'll have to fire up CM-GM when I get home (I'm at work now). Any other move by white and the attack is over and they go to the end game.

    Without having seen the game, anyone want to guess who was playing white? (This is not from the game, it's just a variation that could have arisen during the game.)

    Qxg7 Kxg7 and black seems to be doing fine to me...

    The king can't take on g7 because of the White rook on h7.

    And this is why I'll always be a mediocre chess player. My intuition screamed Nxe6 at me. Fair enough; it's a good first move to look at, if you don't overlook that it's covered. But when I did spot that it is in fact covered, I went on to look for other moves elsewhere... and never even stopped to consider whether I could un-cover that knight move.

    I was thinking something like this:

    1. Bd7 Nxh8
    2. Nxe6+ Kf7
    3. Nxc7 Rxh7
    4. Nxa8 Bxd7

    White wins a queen, rook and bishop for a queen, a rook and a pawn.

    Perhaps I'm missing something here.
