If 0x88 stands for flat data structures, ok. But 0x88 for me seems not to be the most performant flat data structure. And before talking on 64 bit approaches it would make sense to have a top ten hitlist of those based on 32 bit. I have not the idea that bitboards are more performant than flat data structures. >I would be very happy, about a discussion :-)) Because of the fact that most people would still not use a 64 bit OS, it would be interesting to discuss 32 bit experiences first.
