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?
Congrats, finally you got it! :)
