The McDonnell-La Bourdonnais encounters marked the beginning of modern chess -- a set match of serious games, all of which were recorded and published. This was the Frenchman’s most famous win of the match (really a series of six matches, won by La Bourdonnais +45, =13, -27), in which we have the unusual spectacle of a swarm of pawns overcoming a Queen.

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 5. Nxc6
A positional error, strengthening Black’s central pawns, but such niceties were little known in the 1830s.
