A game I just played has mate in 11 from this posistion. In the game however, I managed to get mate on move 47 lol. Hay I was under time pressure ok But lets look at the mate in 11 and please tell me if you can see a different or quicker line, or if you see a flaw in the puzzle. My friend used his new computer program to do this for me and I think he said it's a Rybika. I hope I recorded the right moves

Thanks.

amazing

nice one.

!!!!!!!!!!!!!

Way to hard for most humans to see. Nevertheless white shows black what's up in this puzzle.

Wow!
