Anyone have a list of positions of the longest 6-man EGTB wins that meet 50 move rule requirements? I.E. no cursed wins allowed

This simple 1-liner on my syzygy folder (with some 7-men files and only searching for exactly 100 ply wins) gives:

I don't think this is necessarily the right solution. The longest win could involve captures or pawn moves which reset the 50-moves counter.

I think to do this accurately, you must have the complete Lomonosov files.
They have distance to mate.

Keep in mind that those are DTZ, not DTM.
But looking at the question carefully, the answer is probably correct for syzygy files.
Those are the most distant wins (they just aren't minimal).

I was afraid you were going to say something like that.
I know there must be some mates that are well over 100 plies, I just need some examples. Preferably long ones.

I looked at all the "normal" EGTB sites and didn't find anything suitable.

I think it may be possible to get the statistics for the Lomonosov files.

But they don't take into account the 50-move rule. Whenever they show a mate in more than 50 moves, you can't really be sure about the number of moves it would take under the 50-move rule (it could be more, it could be less).

I don't think the longest 6-men win that respects the 50-move rule is known.
