Still, my intuition tells me that the position with the open b-file and a possible rook invasion on b3 will not be a picnic for white. Of course more analysis is needed to come to a definite conclusion. You know, this game really illustrates the VERY THIN line there can be between a win or a loss. If Fruit would have played 19.Kb1! or I would have had 18... Qc7 19.Kb1! in the book, everything would be in order. I also remind that Diep first wanted to play Rfc8 instead of b3! That was the expected move by Fruit and I recall it wanted to play 20.Kb1! after that move. In that case the world would be in order again for white. After 3 games Fruit-Fritz 9 from the position after 19.Kb1! it is now 3-0 to Fruit. Sigh....
