1 ... 21-27 is also good
After the 21-27 line you cant protect your king afterwards, resulting in an even position.
i don't think so but i have no longer the puzzle in front of my eyesand i don't know how to choose them
lidraughts.org/training/840after 21-27 scan consideres the position equal (-0.1).it takes a few moves, but the capture of the king seems inevitable, resulting in a 7 against 7.
it's ok,thanks youthe difference it's after 1. 21-27, and so on,he can take 16*27 instead of 23*32 because of 21-26.and I didn't see 13-18 and 08-13 while white take 5*37
