Re: Chess Puzzles

It has occurred to me that Ganesh seems to be missing these last few days.

Does anyone have any ideas to why this is so?

Nice puzzle. It's so tempting to take that queen out with the bishop smile.

Excellent job, Ganesh and NullRoot! Bravo. big_smile

Fancy another one? Here’s another one I made up myself. tongue

#22. As before, White to play and mate in two moves. This one is a bit trickier (difficulty level: 6) so good luck. smile

I really need to get back into chess. I think I'll have to learn all over again though!
