Qb3 f5! will be the new line. We should have organized a computer search >here, it looks like tomorrow might be a turning point in the game. I have put my vote in for 18. .. f5! as well. I don't find computers that helpful at this type of chess other then checking my tactics as I play through some of my ideas. Below is what Hiarcs 7.32 thinks about the position. Only after 1 hour does it start to see the weakness in the move 18 .. Nd4?!. I doubt if Hiarcs 7.32 will ever think 18. .. f5! is the best move in this position or any other program, but I could be wrong.
