This position is from the game Yace-Junior 7. Here Junior saw
some opposition with the kings on e6-e4 or e6-g4 and evaluated
the pawn ending as a draw. Black played 14.-Rxe3?? and lost it
since white can force a passer on the k-side and then go eat the
pawns on the q-side.
Test: Avoid the move 14.-Rxe3?? for black. 14.-Rh1 or similar is okey.
