But i think that Rc7, f3 or Qg3 are clearly better than f4. The positions looks promising for white, and i think there was already a better alternative to 31.Kh1 one move before. But also black has a nice battery now and the queenside pawns become very important. IMO the position is interesting for several eval aspects. How to combine KingSafety, doubled Rooks on file, Rook on 7.rank, (passed) pawn or candidate evaluation. IsiChess needs 19 minutes to find Rc7 with following PV few minutes later (depth 14/25) 32.Rc7 Bxe5 33.dxe5 R7a8 34.Bxb6 Rfb8 with score of 0.49. Before f3, Kg1(?), and f4(?) were best candidates. The last f4-PV was 32.f4 Bd8 33.Kg1 b5 34.Rc5 Qxb3 35.d5 Bb6 36.Kxg6 fxg6 37.Qxe6+ Kh7 38.Qh3+ Kg8 with draw score. Gerd
