I think this is an interesting video by GM Yasser Seirawan. He looks at one of his student’s games in a French Exchange. I am searching for greater clarity when explaining to students why the centre is so important in chess and this helps. I’ve always talked about the centre as being e4 d4 d5 and e5. In this Yasser talks about a bigger centre with the corners f3 c3 c6 and f6 and describes it as being higher ground.
I follow it with a game I played in the York Summer Tournament last week. A good win for the Solid (Rubinstien) French. I can’t say I would have resigned when White did but it is 90 minutes a game and I was well ahead on the clock. Akiba!
