Perhaps White was afraid of a ...d5-d4 break, but it is unclear how he can organize this without the e4-knight falling.

The king might be safer in the center, but its pieces are not. Ironically, it turned out to be Black that used the f-file that White voluntarily opened. I suppose this is not too surprising, since White had already played several committal pawn thrusts. A good lesson on how to evaluate captures towards the center. } 25. Kd1 Rxg3 26. Be1 Rxg2! 27.
