Games with three en passants Games with two en passants in them are are uncommon, and games with three are exceeding rare, and four has never been achieved as far as I know.
I only know of four games with three en passant captures in them, with game #2 arguably being the most famous one because of Tim Krabbe.

Can more games with three en passants that exist be found?
I made a program that reads PGN files that contain thousands of games.
It read 1 317 676 games and found six that fit the criteria.
