There's no rush really, he can't defend it or move it out of the way.

The best White can do here is continue exchanging, as the Queen has nowhere to run: 23.Qxf2 Bxf2+ 24.Kxf2, leaving himself down: R+B vs Q+P. He could probably play on a bit; Black's setup needs to be reorganised before he can really start to make the material edge count. That sometimes happens when a line of play leads to material gain. Interesting game: White had chances to turn things around, but maybe that the saving move was a2-a3, ordinarily a despicable little move, made it hard to find.
