The idea 1.Txh5 has already been mentioned: 1...gxh5 2. Lh6, yes!, cuts the king off on the back rank 2...Sf1 3.b5 - now black can not take with 3...axb5 due to 4.cxb5 and white creates a passed pawn with a5-a6, hence 3...Sg3 4.e4 h4 (moving the knight back and forth does not help either) 5. c5! - now black has to take with 5....dxc5 otherwise white will play c5-c6 winning again by creating a passed pawn - 6.b6 cxb6 7.d6 Sh5 8.d7 Sf4+ (a last try) 9. Ke3 +-
I think that is the winning line isn't it? ; if Black does not take back the rook on h5 white should win as well (the knight on h2 seems to be lost), but the lines are not that forced I think.

Rather good! I write it down as an overseeable 'move chain'. :)

Rxh5 gxh5
Bh6 Nf1
b5 Ng3 (3. e4 or 3. c5 work as well: the idea counts!)
e4 h4
c5! dxc5 (Other black moves lose as well, just try it out.)
b6 cxb6
d6 Nh5
d7 And white wins, but nevertheless black can extend the game a little bit by playing the useless 8. ... Nf4+.
This possibility to play 8. ... Nf4+ is the reason why neither 3. e4 nor 3. c5 nor 3. b5 is the fastest way to win.

What is the fastest way to win as white after

Rxh5 gxh5
Bh6 Nf1
??? :-)

Okey, then 3. h4 in order to prevent black playing h4 himself; with that move the black knight cannot go to h5 any longer and is stuck in the corner. That should be the right idea, right?
