I also gave a couple of them much more time, just to check, but the evals wouldn't change. If you know you know and if you don't you don't...;) It was interesting to notice that Deep Fritz seems to have less understanding of such a position than Fritz 5.32. Deep fritz is also more likely to steer into a similar position than Nimzo 8. Because it thinks it's winning. Sune
