I don't see how black can ever escape the >checks. Bob I looked at it again and it appears I really underestimated the position! After 1.Qxe7+?? ...Ka2!! going to b1 and it really goes down hill for White quickly! I should have seen this...arrghh! getting rusty...."creak"....sigh... Terry P.S. 1...Kb3 is ok I think but Ka2!! and White will have to resign, Black will get out of check and promote his pawn. Try it yourself, you'll see White starts to lose ground for grabbing the pawn. It's a tricky endgame and Fritz 7 is slower than Tiger to spot the loss. HIARCS 8, Junior 7, Shredder 6 all see a lost position but not straight away. Only Tiger spots it instantly! Bravo Christophe! Juni
