Henrik Juel: Popeye says 1.Se7 and 1.Sh6
How does the Bosma condition change this?
The intention is probably 1.Sh6, as 1.Se7 entails far more duals (2020-11-14)
A.Buchanan: 1. Sh6? fails to 1. Kg8,La2,...,Le6 as can't unoverload g8. 1.Se7! has duals after Lg6 & Lg8. This isn't great but in better shape than many of the others (2020-11-14)
Henrik Juel: Thanks, Andrew
The weird condition is trickier than I thought (2020-11-14)
A.Buchanan: Haha yes Henrik: they are hard to debug: because it's always unclear whether a piece, of either colour, is helping or hurting :) (2020-11-14)
