5... Bf5 · Czech Variation
[edit | edit source]Black develops their light-squared bishop. This is possible now because the threat of Qb3 is no longer present thanks to the pawn on c4.
White's main options are Ne5, e3 and Nh4.
6. Ne5 is the central variation, which is the most popular response at the master level. White plans to recapture the lost pawn with the knight instead of the bishop, preserving the option to fianchetto the light-squared bishop instead.
6. e3 is the Dutch Variation, where White will recapture the pawn with the light-squared bishop and prepare the move e4.
6. Nh4, the Bled Attack, chases the bishop away and closely resembles the structure of the Dutch Variation.
