Then in paderborn 2001 i used a better implementation with big reduction factor (R=3) and also in combination with other extensions. The reason i have them inside diep now is a) diep doesn't search very deeply so overhead isn't too big then b) to solve testpositions quicker otherwise i need days to solve things However what i notice is that in mainlines in complex positions the value of singular extensions is very limited. Of course if i'm already won i see mates way before my opponent sees them (in middlegame) or i see a win way before my opponent sees it, as well as that Rxf7 move which ferret played against gandalf i see within seconds with within 90 seconds the right score, but after all the only impact of singular extensions is that they give a psychological good feeling "i'm not going to lose because of a cheap trick if my program messes up". Of course combinations can only be there and getting outsearched is only important if a program plays completely anti positional chess. In normal game play and in sound positions, there the value of SE and similar extensions gets hugely overrated i think.
