Dutch GM Sipke Ernst will teach you how to win with the Exchange Slav.
Many chess players tend to underestimate the Exchange version of Slav. They believe, quite incorrectly, that Exchange Slav is very drawish and has no winning ambitions whatsoever.
Although there are some lines that lead to “safe positions” if white chooses to… there are also many other lines leading to sharp, unbalanced positions with TONs of play.
There are plenty of possibilities for White to start an attack and to fight for a real edge.
Exchange Slav is becoming more and more popular at the Grandmaster level. It has been played in World Championship Matches, Botvinnik used it to beat Tal.
Nowadays very strong GMs play Exchange Slav as well. For example, Wesley So recently managed to upset Magnus Carlsen with this opening. Both Kramnik and Carlsen have Exchange Slav in their repertoires.
