I thing that solution is to pick all pawns. (eg. this situation, but there is the white to move)

Black has King on h3 pawns on h4, g4 and g3
White has King on h1

1...g2+ (only move) 2.Kg1 now both legal moves 2...Kg3 and 2...g3 are stalemate.

There is doubled pawn. With doubled pawn this situation is not problem, eg.:

	Not if we're talking about whether it can be drawn without the king (The point being that even that is non trivial to achieve, so no hope with the king included!).

	That's not a legal position. Black is allowed a King.

Not always, for instance there are pawn-stopping positions with a K vs. three united pawns. Kyle, please provide one example.

	He's banned even doubled pawns, which does make it impossible without contrivance from the 3 fold rep laws etc (Goodness 3 non doubled pawns generally (always?) force a queen all by themselves and the king hardly hurts!). Probably a few answers with them allowed - force the loss of one pawn to avoid stalemate at the start then you've got a draw with doubled a/h pawns etc.

Takes cooperation from both players but you could legally have that position where moving the king to avoid stalemate is drawn due to breaching the 50 move rule Or have white winning on time..... The assignment is clear: three black pawns and king vs white king. Black is on move. Each pawn is in another column and all pieces are on right side of chessboard (e1..e8). There are apparently a solution when there is a draw....

	This position can't be Black's move
