A Puzzle no Grandmaster solved until Tal solved it

great puzzle and hats off for "Tal" the magician of riga

The one thing I feel slightly lessens this puzzle is that the knight promotions are defensive moves, the task of moving the bishop around to find a new checkmating square is easy. I prefer UnderPromotion puzzles where the side with the objective is the one having to make multiple UnderPromotions, like this one:

Any other promotion at any point doesn't just not win, it loses! Hard to beat this one!

Really hard

Follow up: Bd1+,Ne2,Bxe2+, Nf3(forced) Bxf3#

wait wait wait hold up why underpromotion

mind blown

If not, Bishop mates in one

To prevent the bishops new mate in 1 square each time it repositions itself.

Very nice! 🙂
