2016-03-01 - Update Line 245[November 01, 2017] Updated Opening Line by GM Borki Predojević:
Semi-Slav, Vienna Variation

[Line 245 : 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 dxc4 without 5. e4]

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.

In case of the Queen’s early check 5. Qa4+, Black gets decent positions with any of the following three moves: 5… c6, 5… Nbd7 and 5… Nc6.

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.

Black also has several good replies to 5. Bg5, such as 5… a6, 5… Bb4 (transposing to Line 249) and 5… c5, with roughly equal game in all instances.

[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?
