I got +2.01 on Kc2, and then +2.21 on Kb1. This one is hard because the pawns can move. And to Peter, no, I don't have that position. It was published either here on on r.g.c.c., I think here, at least a year ago and probably longer. If someone has CCC indexed, they might be able to find it if they look for posts by me that contain "50" or "fifty". bruce
