Both good puzzles. I liked the second one best, but maybe thats because I have an endgame fettish! If I was in that position, I probably would have played something stupid and drawn it... Evidentally I still need improving!
2 puzzles i created
thats very true Grobe . . . . and there really isnt a place where a pawn promotion could have given that. however the positions are good hope to see more =)
the middlegame puzzles are both excellent, great variations on important tactical patterns everyone needs to be familiar with. i particularly like how you've managed to get some red herrings in there :)
the endgame position, while quite neat, relies on black blundering. mating with bishop and knight is not easy, very few players can do it.

I have just added a puzzle that I created that I think is very difficult, and hopefully flawless, please comment!
one is a easy endgame puzzle
one hard endgame puzzle
the others are a bit tougher middle game puzzle
