In Response To: Bearoff checker play (detailed lesson in response) spoiler RO at the end (Max Levenstein)

The table below should give an idea of when and by how much one play is better than the other. For each of White's rolls, the table gives Blue's Match Equity (ME) having played 4/off or 3/off 3/*2, and the weighted difference (nondoublets being counted twice) between the two.

Match Equities are from 40 Gnubg 2-ply 7776 trial rollouts.

White's Response	4/off ME	3/off 3/2* ME	Weighted (dis)advantage for 3/off 3/2*	comment
44	75.351	87.777	12.426	fan with 4-4 is very big
41	82.524	87.777	10.506	fan is big
31	83.064	86.319	06.510	31 is barely better for White than fanning
11	83.064	87.777	04.713	fan is big but tiny 11 is bad anyway
51	81.824	83.582	03.516	from gaining ~0.5 rolls and ~1 crossover
43	80.588	82.342	03.508	(" ")
64	77.652	79.335	03.366	(" ")
53	79.482	81.142	03.320	(" ")
61	80.686	82.342	03.312	(" ")

65	76.880	78.383	03.006	(" ")
33	76.245	77.418	01.173	(" ")
62	79.746	79.834	00.176	average racing number; hits but leaves 18 return hits from the bar
55	75.118	75.174	00.056	still some slight gammons chances
66	75.118	75.140	00.022	2 doublets vs. 54 still wins a gammon
21	83.017	80.955	(04.124)	worst racing number; hits but leaves 18 return hits from the bar
22	82.506	77.047	(05.459)	numbers that hit and safety mean fewer gammons lost
52	80.686	77.486	(06.400)	(" ")
42	81.824	77.480	(08.688)	(" ")
32	83.130	75.549	(15.162)	the small racing number 32 hits and efficiently covers
