    I got it, but why does black play Nd5 and not Qd7? A little help please.

    If Black does 2. ... Qd7 instead of Nd5, then suppose White does 3. Nb5.  If Black responds 3. ... cxd5 then White does 4. cxd5+  and things look bad for Black.   If Black doesn't take the Nd5, then the next move for the N is Nxa7+.  (I can't find a lot of moves for Black for move 3 if he chooses not to cxd5.)

    Rich, your analysis is questionable. After 2. ... Qd7 3. Nb5, cxd5 is not a legal move. Perhaps you meant cxb5. That's not a legal move either as it would put the black king in check.

    I believe you are correct about Nb5 with the Nxa7 threat.

    This is a very interesting problem.  I played c5?  If the knight moves a4 Qb3 traps I thought.  Black just plays RxN.  I didn't see that.  But if the black night returns to it's orginal square, the Bf4 wins the queen.  I think most of my worst blunders come from understanding the position but not completely

    Great puzzle. Aside from Black being able to just play Qd7, after cxd5 Black will play Qb6 and will not lose a Queen, as opposed to Bxc7 where White will take both Black's Queen and rook.

    This is a good puzzle, which I missed.  Black cannot play Qd7 as suggested by some since whites reply Nb5 threatens Na7#.  Black must then take the knight with cxd5 to which white replies with cxb5+.  Black then has only three choices, 1) blocking with the Q on c7 which loses to Qxc7#, 2) blocking with the Q on c6, which loses the Q to bxc6, 3) blocking with the knight on c4 which loses to Qxc4+.

    I suppose, rather than taking the knight on b5, black could move the R on d8, giving the K some breathing room, although then after Na7+... Kd8, white can move one of the Rs to d1 pinning the Q to the K.  Either way, black is in trouble.

    I looked at Bf4 attacking the Q, but did not do it since I thought Qd7 worked and Bf4 accomplished nothing..... wrong.....  good puzzle.

    You must be thinking of Problem 0039141.

    I am not so sure on this analysis. First of all, the Source & Analysis doesn't mention the 19. Qd7, which is per se a "bug" once it is one of the most immediate moves; it should be written there why it is not a good move.

    Second, not taking the knight on b5 and moving Re8 instead seems as well a reasonable move. If Na7+, Kd8 is a safeguard. Sorg67 mentioned that one could pin the Queen with Rd1 upon that, but Re8-1+ forces white to "unpin" in an equal trade.

    Instead of Na7, I also found Nd6+, which is as well not a mate. Black loses the rook, far better than losing the queen.

    Please, could a moderator clarify? (and add the answer to the source?)

    Assuming I understand your line correctly, I do not think black breaks the pin that way, because after 22. Rad1  Rxe1+, 23. Qxe1. 


    Black has exchanged rooks, but is still pinned, and will lose the Queen for the rook.

    i would have taken the queen!

    Here's the problem: No one below Master level sees this line to its end when looking at the beginning of the problem.  What's the tactic here - When there is no tactic, just threaten the Queen and see what happens?

    Phaedrus, I agree with you, it's difficult to calculate everything to the end, especially in a few seconds. Still, what can be seen below master level is that Bf4 is the move which increases Black's trouble because even if Black just moves the queen away, the pin on the b-pawn and Nxa7+ are serious threats. Sometimes, it's not "if you found a good move, look for a better one", but "if you found a good move, just play it."

    (Qd7 doesn't work because White's rooks can threaten the queen along the open files, and if the queen moves into safety, Nxa7+ drives the king into the danger zone. There are many ways for Black to somehow defend, but each of them loses material.)
