The game below is not logical, or even plausible by any stretch of the imagination; it is, however a sequence of legal moves leading to a position in which Black's king is in check (and about to be mated), but cannot save himself with a pawn drop for the sole reason that it would give an illegal checkmate to White's king.

By the way, when entering these moves, I noticed an odd glitch. When I tried to play 9... K 7f-8g, a message appeared saying that the move was "not marked as legal". Strangely, the preset still allowed the move (but would not allow moves that truly were illegal). This may be connected to another glitch I stumbled across a couple days ago, which caused one of the Shogi presets to prematurely end a game by false checkmate. The log where this occurred was: tamandua-cvgameroom-2015-175-942
