This game contains one of the most remarkable double check combinations of all time. Mason, playing white, has the advantage for most of the game. He eventually wins a few pawns, but it is unclear how he will infiltrate black's seemingly solid position.
However, Mason begins a neat combination that sees him sacrifice both(!) of his rooks. In return, he springs a double check that wins his opponent's queen. The rest of the game is just a matter of mopping up.
