Nalimov = DTM (distance to mate) Thompson = DTC (distance to conversion, i.e. transition to a situation with less pieces on the board) The Nalimov TBs can be compressed so they are much smaller than the Thompson ones and can efficiently be probed during the search.

The Fritz Endgame Turbo CDs contain the most important 5-man TB's, i.e. the KxxKx stuff. They leave out the unimportant KxxxK cases such as KQQQK since they are trivial anyway. --- Shep
