Best UnderPromotion Endgame Compilation

Another great bishop underpromotion example I found online:

White can promote both pawns to a queen, but either results in instant mate in 1 by the rook! Kf8 leads to the same mate, and kd8 allows the black king to win both pawns! F8 = N+ is the only winning move to deflect the black king from the mating net and then promote the g pawn to a queen winning! Very realistic endgame! It's also important to point out that unlike most underpromotion studies, where the underpromotion turns a loss into a draw, or an otherwise drawn game into a win, this is the only one I know of where the Underpromotion turns a Loss into a win. Any other piece promotion loses, and the only promotion that doesn't lose, wins.

I cannot think of a position that turns a loss into a win. (Plus this position is delicious)

The position I posted early on with the promotion to 8 consecutive Knights, as well one involving a rook vs 2 pawns endgame, underpromotion was both the only way to win and the only way to not lose. In both cases because the side about to promote was under a mating attack and promoting to knights for example, were the only way to give checks. Oh and another simple example of this:

Anything else loses.

Just thought I would post the original 8 Knights underpromotion mate in 8 that your favorite 8 Knights underpromotion STUDY is derived from. It's a mate in 8 by American composer William Shinkman from 1908:

Which André Chéron turned into a study in 1964:

And André Chéron created another DIRECT MATE in 8 for the 8 Knights underpromotion, again in 1964:

If I'm correct the added pieces makes it so that not only is it the only way to win, it's the only way not to lose.

Well I think that was established earlier in this thread by @MARattigan in #269  AND @Rocky64 in #272, I was just pointing out where the original idea came from.

Here's a very nice study that has 3 mandatory underpromotions in it to seal the victory:

White to move and win

This is the first one I've seen that requires 2 opposite colored bishops underpromotions, love it. Adding this to my collection for sure.

Great

Here is a study that requires an underpromotion to win, all other moves lose:

Well, here we go, the one-solution 15 move underpromotion puzzle, I made it.

and this one, mate in 8, I made it again

No offense, but what an absolutely insufferable piece and board setting LOLOL!!
