pm with the answer if you think you got it. It is a mate but I'm not going to tell you in how many moves. Its black to move.

Edit: Qxf2+ is a mate in three but look for a different mate trust me there is one.
Originally posted by zzywokay then I'm wrong but find a mate that is more spectacular and gives more options to white but everyone leads to mate the longest defense is 11 moves but I doubt anyone would be able to find the best defense over the board except the best players.
1... Qxf2+ 2. Kxd3 (forced) Rad8+ 3. Kc4 (forced) Be6+ 4. Qd5 (forced) Qc2#
Looks like a forced mate to me.
