At the price of more lookup cost because 149 GB don't fit into the RAM. Plus that most of these lookups occur in branches that would have been cut off anyway. So it may well be that there is no real advantage; it might even actually weaken the engine.

Yeah, that's why i've switched to probing 5-men during games with 6-men adjudication. CuteChess 1.0.0 <

I do not think I've had this problem in earlier versions...

Any thoughts?
Nevermind....user error. :roll:

Yes. Certainly agrees with naked eye observations of Engine-Engine Matches. Practically speaking, results are more affected by strength of the Book, Engine and Hardware, in that order; Syzygy is a distant 4th, if at all.
So, 5-men Syzygy is certainly more than enough in the real world of Engine-Engine Matches/Tournaments, except for the Purists.

I think there is a diminishing rate of return with table base. And engines evaluates are so good they mostly play the endgame based on evaluate rules just fine. Throw in some 5 or less man table base your sitting tall on those rare endgames where a little more is needed. The chances of finding a situation where a draw would not be got or a win lost without 6 man must be rather low in my view.

Rule of thumb ->

6-men for analysis

5-men for engine games combined with 6-men adjudication [CuteChess 1.0.0]

Agreed, although I currently only use 5-men for adjudication as I don't use CuteChess !
