I saw the movie and was wowed by two things: the blind chess match in which Holmes wins with the move Bishop-Bishop 8, discovered check; and the mental fist fight they have in their minds. It's such a creative way for two geniuses (genii?) to do battle.
My question is, was the match that they had real/plausible? Was it based on a real, historical chess match? And was it even played as chess masters would play?
My first instinct was that they took a historical and famous chess match, and my gut feeling is strong. But I could be wrong. And anyway, which chess match is this? I figured, if it's a historical chess match, many users here will have studied it before.
I tried to get a screenshot of the last configuration of the board, but they never actually show it.
Instead, I know that Moriarty plays White. His opening move is c4. When Holmes moves again, he is shown to play d5, some turn after he has played e5 (but we're not sure how many turns after). On the bright side, I have a this screenshot when he plays d5:
Finally, I have the list of moves they made during the end game, when their blind match started. I'll list their alternating moves according to how they said it, as I don't know how to write in notation.
Holmes: Bishop takes Knight, check
Moriarty: King to Rook 2
Rook to King's Rook 3
Bishop to Rook 3
Bishop takes Bishop
Rook to Bishop 4
Rook takes Rook
Pawn takes Rook
Bishop to Bishop 7
Queen takes Knight Pawn
Bishop to Bishop 8, discovered check, mate
