I don't understand the >motive to do otherwise. The motive is efficiency. Say some user gives your program 30 MB hash, if you do the power two thing you can only use 16 MB, thats 14 MB wasted. Sure you may run 0.1% faster, but with a smaller hash you also get a bigger tree. Of course you can try and find some other way to use those 14 MB, like allocating another small table, maybe that will use 8 MB, so you have 6 MB left. Then you can allocate another table.... Frankly, I find that silly, chess programs are complex enough as it is. -S.
