He claimed that there is a price of losing search depth but I do not agree with it. The opposite. It may increase the search depth because you do not have to search some lines when you know the result so you can increase the search depth in other lines. It is also possible not to use tablebases at the leaves of the tree but only some plies before the leaves(in case that there is a capture that lead to the right number of pieces) and in this case it is clear that the time to search some plies is bigger than the time to look at the tablebases so you only save time. The only case when you lose time is when there are not tablebases hits because you have to check if the number of pieces is smaller than 6 after every capture but I believe that this time is almost nothing and it is not important(I guess that programs may be 0.1% slower because of this when there is no tablebase hits and the meaning of this is clearly less than 1 elo rating).
