I've made another puzzle with the variant. Mark's ? re: moving into a poof and whether or not it would be able to capture vulnerable pairs and my response to him were the inspiration for this one. I suspect it will be fairly obvious, so no prize, but kudos to the first correct solution. The puzzle is as follows:Black stones at E12,F10,H6 and 11,J8,12 and 14,K7,9 and 13, L6,8,11 and 12,M7,9 and 10, N8 and 12. White stones at:F11,g12,H7,8,9 and 10,J10,K10,11 and 12,L9 and 13,M11 and 15,N10 O7 and 9. Neither side has any captures. White to play to a forced win in 5 moves given best play by Black. I'll just attempt to put up the section of the board where stones are placed on this one; i.e between E and O and between 6 and 15. Good luck!
