Nc6 is more promising, f6 is however the move to neutralise Rh1} f6 40. b5 {
Is Fritz 1 giving the victory away ? Clearly he has problems with thesearchtree
, to scan the 8th halfmove tree completely, and this somehow weakens his play
as he often changes his mind upon the alternatives on the 8th halfmove. The
flex move Rh1 or Rb1/Rb3 looks promising, but the d6 pawn could end up in
blacks hands.} (40. Nc6 Rc8 (40... Re8 41. Rd2) 41. b5 Kf7) 40... Rb8 41. Rb1
