I tried to generate the KR vs KNP tablebases and I cannot do it because my computer has only 256 Mbytes in the main memory(no problem of memory in my harddisk). I saw that even 512 Mbytes are not enough it had no problem to generate tablebases of KQN vs KR after many hours and my logic says that I need more main memory for this endgame because in KR vs KNP tablebases it is possible to solve 48 different KRP vs KN tablebases based on the place of the pawn so it needs only 1/48 of the memory. It seems that the tablebases generator does not work in a smart way and instead of generating 48 different tablebases for the cases that there is a white pawn at a7 and ideas like this must generate all the positions at the same time. I have 2 questions 1)Did nalimov use a machine with more than 512 Mbyes main memory to generate the 5 men tablebases with pawns? 2)Is it possible to generate the 5 men tablebases without enough main memory but only with enough memory in harddisk and the problem is only with the chessbase TB move generator?
