Line 245 mainly covers the following three branches of the Vienna Variation: 5. Qa4+, 5. e3 and 5. Bg5, while the main move 5. e4 is the topic of our Lines 246-247. The arising positions are usually quite dynamic, where both sides have their chances. These lines are not particularly fashionable nowadays, but one can still hardly call them innocuous.
After 5. e3 a6 6. Bxc4 b5 7. Bb3 c5 occurs a position similar to the Queen’s Gambit Accepted, which is rather promising for Black.
[Diagram: White to Move] Black King is stuck in the center, but the central lines aren’t open yet. In an engine game White failed to find the best way to proceed, but in such positions human intuition can sometimes be stronger than the brute force of computer calculation – do you feel tempted enough to give it a shot?
