8.Be2
An unassuming continuation. White refrains from any immediate action and continues his development. Meanwhile, a number of good possibilities have been discovered for Black, and therefore 8.Be2 is only rarely played today and probability tomorrow as well.
8...dxc4
A logical reply, Black makes the enemy bishop move again. Which as you know goes against the basic principles of the opening of moving a piece twice in your opening development.
After black captures dxc4 we have four choices
A) 9.Bxc4 Recapture, the most logical and may be the best choice. [
B) 9.Ne5 Increase the pressure on c4 9...Nd5 10.Bg3 Bb4 11.Qc2 b5 12.0-0
C) 9.0-0 Bring the King to safety Which is a prudent and wise choice. 9...Nd5 10.Bg3 Nxc3 11.bxc3 Nd7 12.Bxc4 Nb6 13.Bd3
D) 9.Qxd8
Capture the Black Queen. A very bold move but lets Black take control over the d file with
