Here is a puzzle from Chess Life, in the Benko's Bafflers. I'd be surprised if anyone can solve this one!

White to play and win, by J. Gunst and Richard Becker.

It is indeed hard. I could never solve a puzzle that hard, but it was very nice. Thank you for the post.

interesting game, had me guessing !

I definitely had to make more than a couple of guesses!

good one......

i was hard.. had to make a lot of guesses..

omg!!!!!!!!! cool!

nice:)

had to make alot of guesses at the first few moves... after that it was almost like repeating... amazing how u can checkmate with one bishop and kind coz of the black pawn... lol...

I had to guess the entire way! (okay, maybe I'm exaggerating a little bit)

that was not that hard, though it was a nice endgame i enjoyed doing it

nice... I didn't know what I'm going to do but I played similar to what would I do in my game and it almmost worked :D thought I would never sacrificed knight at the end...

Nice game! I don't think it was too hard - not saying I could have done it in a blitz though.

Nice game really hard.

i got most of the moves. not boasting or anything. Not a un-understandable puzzle.its on a level i can understand.

All the same its a very nice puzzle and show some good fundamentals of tempos!

HA...solved it...one wrong move at a time...nice puzzle

Brilliant puzzle

That was defintely HARD!
