Fun one, white has lots of good options (overwhelming material lead) but getting mate in just 2 requires persistence as you reject all the mate in 4 options.

Note that the black king is trapped... all you have to do is give check.

The main complication is 1. ...Nf3+ which means that if your first move is not a check, your second move must be Bxf3.  

1. Nd2 (threatening 2. Qc4#  [EDIT: or 2.Qc6# or 2.Qxd7#, thanks 64spreader])

1. ...Nf3  (only way to prevent 2.Qc4#)

2.Bxf3#  (e5 pawn is pinned by the h5 rook)

RE-EDIT:  Darn it, I  missed one possibility:

F1 to D2 then A4 to D7

64spreader, did you forget that 1. ...Nf3 is check?

RD2 then whatever black plays there is always mate in 1

What makes u think the bl kn will go to f3 i cant see no f3 as of yet lol

Sokolov,

1.Rd2 Ne4!  and whatever white does, black hangs on for one extra move as far as I can see

1. Nd2

If Black replies Nb6 (stopping both Qd7# and Qc4#), white's alternative mating move is Qc6#.

Now, if Black's reply to Nd2 is Ne3+, white gains mate with Bxe3# because Black cannot block the mate with e4 due to White's rook on h5.

Quite right, Jonathan. I didn't see that. Those pesky knight promotions!

By my count there are 13 possible responses to 1. Rd2 and they can all be answered with mate. Surprised
