In the variation from the Nalimovs (Lookup), there is no pawn move or capture for 93 moves.

I wanted to try other endgame tables (DTC/DTZ...) but the online access seems broken:

(I'm not sure if they'd have this ending anyway, or only up to 5 pieces/6 pieces without pawns. Can't remember.)

Thanks, these are the Nalimovs too. I was wondering if tables like Thompson's (DTC) or DTZ tables could find a win in compliance with the 50 moves rule.
