The basis for the Powerbook Queen's Gambit Accepted 2019 consists of 168 000 engine games as well as 26 000 games from Mega 2019 + Correspondence Database 2018. In the Queen’s Gambit Accepted 1.d4 d5 2.c4 dxc4 Black is not seeking to win a pawn, but the early capture on c4 rather represents an attempt to rapidly become active on the queenside and then to contest White’s centre – mainly with ...c5, but sometimes also with ...e5.

One of the most important basic positions arises after 3.Nf3 Nf6 4.e3 e6 5.Bxc4 c5 6.0-0 a6. Now White has available to him many natural moves such as 7.a4, 7.Bb3, 7.dxc5 and 7.Qe2. One of the “secret weapons” is 7.b3!?
After 7...cxd4 8.Nxd4 Bd6 9.Bb2 0-0 10.Bd3!? there exist in “humanoid” chess only a few correspondence games, but in the Powerbook you can study the possible variations based on 336 games.
