First of all let me state that I am not a programmer, just someone who enjoys computer chess immensely. I have seen a lot of posts that put down the Endgame Turbo disks because they do not contain all of the TBs, in particular those TBs after the pawn queens. I think it a good idea to reduce the hard drive space required for TBs by pruning those TBs that any good chess program can figure out if its brain was not disabled. It seems the real problem is that those programs that use TBs turn off the permanent brain once the program is in a TB position and then the program gets confused if after a pawn queens and the now simple win (for good chess programs) is not in the TB folder. This is something that the programmers probably did not anticipate originally everyone has seen games where this impacts the result. Now that this has been identified, why can't the programmers tell their programs to follow the TB tree to pawn promotion and reset the permanent brain at that point. Many people have reported that the programs that blunder with missing 5 man TBs play the same ending fine with 3 and 4 man TBs. It just seems that the programs don't know how to think again after they start down a tree and the tree ends before checkmate. A bug fix by the programmers would be more preferable than taking up another 5 gigs of hard drive space. Arndra
