Promoting to your own/the enemy king, perhaps with multiple of one or both sides' kings, is an old one indeed. That joke never has and never will be consistent as to how best to implement a winning condition.

Happy to help. I've loopholes articles like this I've had the shelf for a few years now, will get them out soon enough.

Yes, welcome Andrew! It's good to have you here, my friend.

David Sedgeick, the source that you give is merely a reprint. This problem that shows promotion of a pawn to a pawn to draw, called the dummy pawn, actually goes back to 1851. It was created by Josef Kling and Bernhard Horowitz and it was published in "The Chess Player," on page 76 on 9/20/1851. You...

I find it funny that the king returns home in the diagrammed game, and an interesting post as well you have here.

I'll see if I can get a selfmate on him. That'll show him!

This seems like it would be a cool show if done. The prospect of beating a GM at something might interest many average players.

One last thing-Here is a problem in which the king is left in a quintuple check in the final position!

Good one, Geoff. Now all you have to do is find 2 GMs or two players clearly of GM strength.

If you want strictly GM is GMish players, the 20 year gap between the 1972 and 1992 games of Bobby Fischer and Boris Spassky is an obvious starter candidate.

Here are two chess problems that both show the maximum amount of bishop promotions done so far in study and a directmate.

What's so preferable about it?

It demonstrates the idea more economically.

Norman's study is more PIECE economic, but I presume you mean economic timewise? The mate in two could also be considered more economic clarity wise, since one movers are too easy to do.
