I noticed the time control behaviour, when I asked why Nimzo was playing so fast I got a muttering as response which made me even more suspicious. Since I saw the advantages it made me think and afterwards I implemented such an algorithm also in Rebel which I from that moment on used against GM's, it works great. Against comps I got about equal results but I was too lazy to test the algorithm extensive. I haven't set it to default for reasons you experience now, the impossibility to explain it to the average user :) Ed >... Johan
