I am surprised to read that ordering based on piece square table evaluation helped you so much. I also generate all the moves before ordering them but I still did not try it because I tried other ideas and I did not think that this idea is very important because for the first moves piece square table give me the same information and for the last moves the order is not very important because you can be almost sure that they will fail low. Note that I use 64*64 table for history tables and not 6*12*2 I thought about 6*12*2 and even suggested this idea here after programmers like Tony warten claimed that history tables did not help them but I did not try it.
