Bird's OpeningEdit

1. f4Edit

This is not a very common move; its aim is to over-protect the e5 square which later can be occupied by a White Knight. Black sometimes attempts to stop this plan as early as move one, by responding with e5, the From Gambit.

StatisticsEdit

Approximately chances: White win 35%, Draw 25%, Black win 39%
Estimated next move popularity: d5 49%, Nf6 15%, e5 11%, c5 9%, g6 8%, d6 2% other moves less than 0.5%
