My feelings are about the same on this stuff, but be ready to be disappointed. XiniX has some of this knowledge fe KBBKP. Althought it picks Ka6 from the testposition from BT2630 immediately, it needs 22+ ply to return a checkmate score. Same with KNNKP. In a position posted here a few days ago, XiniX finds Ne3 in 3 ply :) with a +0.4 score :( Although it recognizes about 70% of all wins for KNN, alpha beta seems very resourcefull to find some silly line that isn't recognized. BTW branchingfactor at ply 20 is still only 1.8, I wonder how high the recognition percentage has to be to get it down to 1. ( Not only will a lower bf enabled XiniX to search deeper, it will also give it less possibilities to find silly lines that escape recognition) Anyway, fun stuff, but I don't expect it to make XiniX 50 elo stronger. cheers, Tony > >Greets, Thomas
