Black develops their light-squared bishop. This is possible since the threat of Qb3 is no longer there.

White's main options are Ne5, e3 and Nh4.

6. Ne5 is the central variation, which is played most often at the master level at around 45%.

6. e3 is the Dutch Variation, where white will eventually succeed in their plan to play e4.

6. Nh4, the Bled Attack, chases the bishop away and closely resembles the Dutch Variation.
