[4C2b/1d1E1De1/bdc3Fe/2D3De/5eE1/A1aeAB1a/1e1e1E2/3E1E2]

13+14. Orientate the board, and identify the pieces! Capitals are one side, lowercase the other. Each piece is represented with the same letter (so if an e is a white pawn, an E is a black pawn). Last knight move? (2 solutions!)

[There possibly is a misprint in the above position. In the text, a piece count of "13+15" is given, but there are only 14 lowercase pieces in the diagram position]

[4C2b/1d1E1De1/bdc3Fe/2D3De/5eE1/A1aeAB1a/1e1e1E2/3E1E2]


11299 - Hauke Reddmann
Die Schwalbe, Heft 191, October 2001

What is the maximal material advantage [Q=8, R=5, B=N=3, P=1] that white can have without being able to win? White should neither be stalemate, nor be forced to stalemate black on the next move.

a) Possible from a game
b) Position may be impossible

[The author's solutions are for a) > 90, for b) >> 400, but < 500]
