White to move, mate in two. I CAN'T SOLVE IT!!!!! HELP!!!!

With these sorts of puzzles, pretend it's black to move... try to find a good move for black... what you'll notice is almost all your moves allow a mate in 1. When you find the move(s) that don't allow a mate in 1, you're almost done solving.

Yeah, seems that after Rd2 there are several forced mates.

By the way the FEN and PGN of the original post are wrong, they have Black to move. Change that "b" towards the end to "w".

kn to d2 then q to c6 checkmate

There is only one right answer.  All other answers do not work.

The only answer is as follows

dxe5

Note that the knight check is a ghost threat as in this continuation Bxf3 is checkmate in the second move.

There is no defense for Qe4#

If c4 then Qc6#

How did I solve this?  The answer lies in cutting off the escape routes to the enemy king.  I first realized that moving the queen away from protecting the pawn could well mean the pawn could be eaten next turn and thus give the king more breathing room, also c4 could be a possible escape for the king if the queen moves from that starting position, along with the pawn being left undefended as I already stated.  I later noticed if white saced the rook  for the exchange in his first move with Rxg5 and then hxg5 Bf3 would be a possibility, however, black has a defense... e4.  Although white is still winning and can deliver mate soon, it will not be done in 2 moves.  So the answer is to take the thorn in whites side, the pawn on e5, and remove the threat of black taking the white pawn being attacked twice at the same time.  That move, is the simple dxe4.

 While solving this I also noted that whites dark squared bishop, knight, and blacks own pawn, prevented blacks king from moving to the 6th rank.  The hole to consider really was c4 if the queen moved from that square, and the unprotected pawn after the queen moves. dxe4 not only solves the problem of the unprotected pawn, it also connects the rook and the queen allowing them to work together and deliver mate.  The best defense after this would be c4 but as I said it is met by Qc6#, because c4, although the queen is not guarding that escape route, is now being blocked by blacks own pawn. 

@Daybreak dxe5 c4 Qc6+ Kd4.

actually my solution doesn't work because Qe4 is guarded by the knight.  So the answer has to be Qb3+ is Kxd4 then Nb5#.  My problem was that I kept worrying about the pawn

c4 was still a hole to be considered, and when solving the puzzle you should have noticed that the 6th rank was covered in the beginning by two whites pieces and was blocked off by one of blacks own pawns.  Someone already mentioned Qb3+ however they did not give a solution for Kxd4.

Rxg5 ... after bf3 or if black move pawn qb5 or qc6

try all possible checks if there are more then 2 responses than than both need to be mate. Rd2is still okay because white has a easy response.

lol its mate in 2 black can still check and it will be more than 2 moves. must be check or pin to start with.
