user8751: After the last problem which was very hard I'm bringing you another one which is easier than the previous one. The position is:
[fen "K4R2/RQ4B1/2n5/3q2p1/4PP1p/3p4/pp6/1kr5 w - - 0 1"]

White has just played Qg2 and it's going to lose very quickly. What is the winning move for Black in this position?
This problem is taken again from the Chess Tactics Server.

user7297: White threatens mate on g7, but

 1. ... Ne1 pins the queen (and threatens Rf1#; Qxe4 won't stop that) 2. Rxe1 Qxe1+ 3. Qg1 Rf1 wins the queen

and the remaining endgame is easily won for Black.
