So, a very, very unfortunate loss for levy in this last round, it's a game where he had a clear advantage out of the opening, to me, I think a lot of it has to do with calculation, and just lacking in confidence, now levy might have something else to say about it, but my guess here, is that levy has to have looked at the four pawns in the past, I don't think he just played this opening for the memes, and based off of that, what I really think levy forgot in this situation, was that when you get the ben-oni structure, even though the knight goes to C7 versus D7, you can always play for G4, G5, without castling, but even here, you can still play G4 and G5, so in all these ben-oni structures on the four pawns, white should be trying to push P on the king side, when black exchanges the bishop, and in levy's case, I think he should have recognized that, and realized that the plans are still exactly the same, had he done that, he would have won the game, for sure.
