white to play and draw. I composed this puzzle years ago, but did some modifications (made it bit harder) today. i think and hope that there is only one solution, but if you find more please inform me.
please dont post the solution right away. EDIT: And do not use Fritz!

Here is my version of your position (White to draw again). (Perhaps with a few more improvements this idea may acquire the form it deserves):

I'm not crazy about the heavy-handed wR sacrificing in these versions. Perhaps something a bit more minimal might make a good impression:

White draws
That's actually pretty good :-). If some more foreplay is added, it'll make a really hard study. I'll think about it but that is definitely a shot in the right direction.

involving promotion.
Why do you need the pawn at h3? This is interesting, I will consider it. I was thinking of adding black bishop on "f7" in my variation of BigDogg's position, but alas Black wins, there. Your idea of underpromotion is rather good.

without the h3-pawn, white can promote to a queen on f8, and then move his queen to h8 and then h1 and stop the a-pawn. dont know if thats still winning for black, but its definitely more complicated.

Trouble here is that the key move, 1.fxe8=N+, is too brutal and obvious. Any other piece gets extinguished by 1...Re7+ in response, so promoting to N is the only real option.
