JUST POST YOUR SOLUTION IF YOU WANT and

I WILL POST MINE LATER...

white to move mate in 2

Rcxf7 Nxf7 Rxf7 or Rfxf7 Nexf7 Rxf7 or Rfxf7 Nhxf7 Rxf7

But the problem with the first and last solutions is that the bishop can block - It would take three moves.

Edit: I see it now: Rxc4 bxc4 Qxc4

solved:D

Interesting  :)

I'm thinking of 1. Kc8 so white can unblock the bishop on a8.  This helps control the f3 square and threatens 2. N1e2#.  Black's rook and queen are pinned so black cannot use those pieces to help prevent the mate threat unless black tries 1...Qf5+ 2. Rxf5# or 1...Re4 2. Qxe4#.  The only other ways that I see that black can prevent 2. N1e2# is to play either 1...Nf3, 1...Nd3, 1...Nd7, or 1...Ng6 then 2. Rxc4# or 1...Nc6 2. Rcxf7# which results in double attacks on the black king.

Edit (addition made by phmilet):

There is one last way for black to prevent 2.N1e2#, which is 1... e2 2. Qd2#.

White can't play 1. Rxc4 because it is pinned to the black queen.  :)

Okay. Didn't see that. Thanks for pointing it out!

No problem turkey.  :)  There is a lot of tactical possibilities in this puzzle.

I think ypu nailed it

kc8 for me is the key move and it can create so many options... same as with einstein.

There is one last way for black to prevent 2.N1e2#, which is 1... e2 2. Qd2#.

Thanks  :)  I missed that one.  :)
