In a real game I would play Ng7+.
If Kg6 then Rxh3.
If Kg4 then Rxh3, Kxh3, Nxe8.
I would not settle with a draw, I go for a win.
But this is a study, not a real game...
While I can't be sure I think the answer may lie with 1. Be4+

My first idea was Ng7+ too, but it always ended in a Black win somehow (though its pretty difficult to find the best moves always).
Now I'm thinking about Be4+, have a feeling this is it. I found some draw lines there, but nothing solid yet.
It's a pretty interesting puzzle.

however i do think the first move is ng7+....but after that everyone has made the error of going for the Rook...
here's what i have so far....
Ng7+ Kg4 Nxe8!! [if Rxh7 then Nf6+!! Kh4 Nxh7...the bishop and mate at h1 are defended]
Black still has threats but the bishop is out of the equasion...

haha....its actuallly more complex than i thought......
which leads to me to a question -- in order to gain the draw is it assumed someone makes a blunder? or perfect play for both?

so I set the task to Crafty - so far 700000000 (or so) nodes and it still hasn't found a draw - or anything close.

I'm probably not good enough to get this, but after spending a lot of time with a friend looking at this, we got:
1. Ng7+ Kg4 2. Nxe8 Re3 3. Rg7+ Kh4 4. Rg1 Na4 5. Nxf6 Re2 6. Rg4+ Kh3 7. Bg2+ Rxg2 8. Rxg2 Kxg2 9. Ne4 Kh3 10. Bc5 Nxc5 11. dxc5 Kg4 12. Nd2 b2+ 13. Ka2 Kf4 14. Kxa3 Ke3 15. Nc4+ Kd4 16. Nxb2 Kxc5
Probably missed some better move on black's part.

when i first looked at this ne8 looked very strong because if Rxh7 you can just fork the king and rook with nf6....
however, even after this black still has the upper hand....
so its.....
1. Ng7+ Kg4 2. Ne8 Rxh7 3. Nxf6 Kf4 [Kh4 is a blunder for Black] 4. Nxh7 [I'm unsure of this move another possibilty is -- 4. Bb8+ Ke3 5. Bxc6 Rg7 ] Na4 5. Bc5 b2+ 6. Nc3+ Kc2 7. b1=Q+
Blacks Queen can now mop up the board and white hanging peices, with the addtional threat of the A2 pawn promoting.
if Rxh7 is the strongest move for black then it makes your entire line redundant.....(this is of course, assuming i havn't made any errors)
