Drawing by underpromotion

@Mollus you are good at creating stalemates. Can we collaborate ?

Very nice games @GM01 but I fear the requirements in the inital post can only be completely fulfilled by artificial positions.

@savagechess2k I like crazy positions but I'm not that much into the chess composition rules. I wouldn't win a beauty prize but maybe someone has fun modifying them into good problems.

Semi offtopic (no under promotion, but draw by stalemate) a joke problem I once created:

It proved to be surprisingly difficult, with even Stockfish needing quite some time to solve it even though it should only be a joke and not difficult.
But knowing that it's stalemate will make it rather easy anyway.

Probably pretty ugly composition but ... how to draw?

Here's a realistic endgame with drawing by underpromotion:

First stage :


Second stage :

Hell yeah! Have you ever seen something like this? All 4 types of promotion are forced in exact that way!?

That is one genius puzzle! He knew people would ask for such a composition about 40 years before^^

Very nice @Sarg0n! I guess we have a winner, perfectly solving the initial question.

And well done Jan Rusinek! (en.wikipedia.org/wiki/Jan_Rusinek)
