Partly agreed. a) Why is it weakening? The results show almost identical numbers, so where is the weakening? b) The opponents played with pb=on, so they played at maximum strength according to your statement above. Do you expect the opponents perform better with pb=off? >The test tried to analyse if results of tournaments with different settings are >comparable. No word about both settings are playing at equal strengths. No? Crafty/pb=on vs. programs a-g/pb=on got almost the same results as Crafty/pb=off vs. programs a-g/pb=on. This usually leads to the thesis that Crafty/pb=on is as strong as Crafty/pb=off. If no, why not? >How long will it take until the last will stop to cunfuse this issues? >Volker First clarify so that I can understand this simple experiment.
