[S J180] "<=1


J (Jump, 8/3 8/2) is clearly the wrong play, though it is not baseless in concept. Give White his 4pt (with 6/4(2)) in addition, and it is wrong for Blue to break his anchor (J becomes the standout play).

I don't have the first edition (1984) of Adv BG Vol 1, and I couldn't find this problem when flipping through the second edition (1991). Possibly I overlooked it, but more likely it was weeded out. The preface does state, "The best problems from the original [first edition] have been retained..." Evidently, the position above was not among the best. :)

The sequence captioned beneath the (above) diagram is "well played" (no checker or cube error worse than –.02). The eighth roll play is interesting enough that I have reproduced it below (with colors reversed, so that the decision is being made by the near-side player). Assume unlimited play (money).

Blue to play 55 (below). Bueller? Anyone?

Nack
