Impossible? No. Hard? Yes!

    Noam D. Elkies composed this outrageous puzzle, saying that its an "old joke" (That's a tip!) I"m sure you'll agree after you see this puzzle.

    Note that White has no way to stop the Black pawn from promoting. Still, it says that White can win. How?

    Wouldnt it be  by doing the same?  Promote the pawn, and then maeuver teh kings and newly promoted pieces?

  • #3

    If black promotes to a knight?

     Let just say Black don't want to play easy and White doesn't want to lose and it a "OLD joke".

    That is hardly fair as I am not that 'OLD'.

     White have given Black odds and was playing without his queen side rook. He castles with the ghost of the rook, claiminghe gave up the rook but not the right to castle. To think of it another way, OLD (I old you it was a tip!) medival chess, a king can make a two square move once- the ancestor of castling!

    That's kind of clever.
