Pogonina vs Chess.com Move 23.
I just stopped by and got the move Bg4 in my head. It's White's worst placed piece.Black also threatens to play Bg5. 23. ... Ng5 24.Bxg5 is suggested. I think White can do better than that. 24.f3 and no one needs to baby sit e4 any longer. True, the push d5 might be easier but let's see. It does not take that much get a play on the light squares. For instance backing with the knight and Qb3. If we see a queen exchange or maybe even if not, once the bishop pair gets into play it can get nasty.
If I were Pogonina I would be tempted to play Bg4. It is also possible now that Nc5 no longer puts pressure on e4.
