    Assuming you are still interested after all this time....  

    After Qxc4 there is a fork at Ne2+ and you get the white Q.

    Poxbox of course means Qxc3, not Qxc4, in case that confused you even MORE. Smile

    that assumes the queen is stupid and takes the rook instead of the knight on d4???

    good problem.  kind of thing that occurs more often in practise than you might think especially at the lower levels.

    It's an OK problem but I think it shouldn't stop after ...Rxc3. It would improve things if black was forced to demonstrate that he understands that he doesn't expect white simply to fall for Qxc3.

    WHite can simply backlash and take black's knight. Please Explain...

    Thanks, JSTORMZ.  We didn't, but I'm sure people were waiting to hear your opinion.

    To those suggesting the puzzle be extended, while Qxd4 doesn't give a 'single, clearly superior line', Qxc3 does.  The problem is currently rated 1374 (I knocked it down another 13 points), which is low enought IMHO to have the computer response be a blunder.

    Yes, Rxc3 Qxd4, but any other line is losing a knight or worse.

    5 Seconds.  Some forks are just too obious :)

    The central problem, which nobody seems to have addressed, is what if White's reply is Qxd4.  In the source game, this is in fact what happens, and there is nothing immediately decisive, although black piles up on the open c file....While I got this one right, looking for the fork, perhaps it should be removed?

    Tell me why it should be kept?

    I agree with InspiredSquare, i do not understand what's going to happen with Qxd4.

    This problem should be kept, but it should be tagged as a Defense problem.  When white plays b3, threatening the rook, how should black respond?  If black retreats along the c file, the knight is lost outright.  If black retreats sideways to b4, white responds with a3!  and the black rook is really most sincerely trapped.  So, black plays Rxc3, knowing that his rook is protected by the threat of a knight fork, and this is an exchange of knights instead of losing a piece outright.  As black is already ahead in material, further exchanges should translate into a winning endgame. 

    The Qxd4 line is in the Analysis: ({12:-5.31} 15. ... Rxc3 16. Qxd4 Qc7 17. Rd2 Rc8 18. Kd1 Rxc2 19. Ke2 f5 20. exf5 Re8+ 21. Kf2 Rxd2+ 22. Qxd2 Bxf5 $19)

    I'll take that as a constructive addition to the conversation, homernh, that the puzzle should be tagged as defensive, makes sense tactically.  And it doesn't assume the fork will happen, as it shouldn't.

    Helped me to refresh an old TT rule: count the material! Black is already a piece up, and White's first move only leads to simplifications and opening lines that favour White. So I suggested to add a "simplification" tag (rather than defense, because Black is clearly active and attacking here).

    In fact this pizzle is a good one. This is not only the best move, because you get this knight but also if the queen takes it back you can do a fork with your knight on e2.
