Pete, I completely overlooked the straight forward a5 as I became so engrossed
in the preliminary Nxh3 followed by a5. a5 does seem to limit black to reply
Bg1. Here is another line for white to consider starting again with a5.

1. a5 Bg1 2. b5 Kf8 3. Kd3 (threatening Bd4) Bxh2 4. b6 a6 5. Be5
This seems to work out to white's advantage too.

Here are some of my Bxh3 ideas, for what their worth.

A. 32. Bxh3 gxh3 33. a5 Bg1 34. b5 Kf8 35. b6 axb6 36. a6 b5 37. Kd3
Ba7 38. Bd4 Bb8 39. Kc3 Ke7 40. Kb4 Kd6 41. Kxb5 e5 42. Be3 Kc7 43. Bb6+
Kd6 44. Bf2 Kc7 45. g4 f6 46. Be3 h6 47. a7 Bxa7 48. Bxa7 Kd6 49. Kc4 Ke6
50. Be3

B. 32. Bxh3 gxh3 33. a5 Bc7 34. Bd4 a6 35. b5 axb5 36. a6 Bb8 37. a7
Bxa7 38. Bxa7

C. 1. Bxh3 gxh3 2. a5 Bc7 3. Bd4 Bxg3 4. b5 Bxh2 5. Bxa7 Bd6 6. Kf1 Kf8 7.
a6 Ke7 8. Bf2 Bb8 9. b6
