Qb6 has been searched to 20 ply now. Be4 is second in the move list, and I
suspect Kf1 will probably be 3rd, followed by axb5.
Here's the output so far for this ply:
20 5339:17 1.59 36. Qb6 Qf8 37. axb5 axb5 38. Qxb5
Rxa2 39. Rxa2 e4 40. Bxe4 Qe7 41. Qa6
Qxe4 42. Qxd6 Qb1+ 43. Kh2 Qxa2 44.
Qe6+ Kh7 45. Qxc8 Qb3 46. Qe8 Qxc3
47. Qg6+ Kg8 48. b5
20 5366:00 2/33 36. Be4
Estimated nodes searched (at 150k nps):
Total: ~48 billion
Ply 20: ~26.5 billion
Based on the times for the last few plies, there seems to be a branching factor
of about 2, as opposed to the 4 which Ernst is getting. I hope this will allow
me to do more plies than I first guessed.
