 For practical reasons and since this is about knowledge, I used 3 min
 of thinking time per program (PIII 800). 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.
