Then on the Queen's-side:

[Event "weak pawns: creating holes"]

Marshall's most famous game was this one, not a Queen's Gambit:

[Event "Gold coin Game"]

When the last move was played, spectators threw gold coins onto the board. Maybe they were settling bets, but I like to think they were appreciating the move!
