Anderssen was a true poet of chess. Brilliant at the queen sack, and finding couter-intuitive ways out of seemingly intractible situations, showing what we gain by sacrificing.

Nice and what could be else

Cool, didn't see the solution right off the top, had to press help key.

wow. nice puzzle. struggled with the first move. didnt see the queen sac.

great puzzle.

Wow! Very cool puzzle. I figured White was hosed once he took the black pawn, but I completely missed the mate.

Nice puzzle
