easy

good.

Wow this one took me a while. 

Nice.

A simple solution to most of the world's problems: Only people with a 1500 FIDE rating or above should be allowed to vote !

Nice twist at the end.

it's a good one, and Jacekk version is even better

nice puzzle

not a good one..g6 move is not forced, hence, not a good move...e6-e5 is better

Intelligence.

It may not be exactly forced, but both roads lead to checkmate - e5 is no better from what I can see

whle black is lost, e5 move averts immediate threat of checkmate..check the variations

Great puzzle!
