|Alekhine - Marshall - What will a 2100 player do with it?|
The amateurs all went down in flames, while Alekhine won the game kind of quickly against
Now let’s see how an expert handles this position:
 The major imbalance is a kingside majority vs a queenside majority. If White can break the blockade on e5 and push his pawn to e5, his bishop will be more active and his pawns will push the Black pieces back. This will not be easy to accomplish.
From Black’s point of view, he wants to maintain his blockade and prevent f4. He doesn’t want to castle queenside as there are several open files. Black could try to work on the e4 pawn but that might be too slow. He should probably try and use his queenside majority and get his king to safety with O-O.
