The Marshall Attack is analysed so deeply that it can be reckoned to be a reliable drawing weapon for Black, that is especially true in the engine room. To avoid it 6.d3 b5 7.Bb3 is becoming more and more popular (after...a6 4.Ba4 Nf6 5.0-0 Be7).
Somewhat surprisingly there is now in the engine room a clear preference for 7...Bb7, whereas in humanoid chess 7...d6 is the move of the top players and also clearly the most frequently played. The Powerbook allows interesting studies with the bishop move.
