The point was: using WDL only, instead of DTM, can lead to infinite winning attempts (in a won position), or to missing a 50-moves draw (in a lost position that needs more than 50 moves for the opponent to win).

Do you realise that using DTM will mess up perfectly fine wins in "chess including the 50-move rule"?

DTM gives a winning strategy / perfect play for chess without 50-move rule.
Idem for DTC and DTZ.

DTZ50 gives a winning strategy / perfect play for chess with 50-move rule.
DTM50 (which is a far more complicated metric than I want to explain in this thread and requires considerably more storage space than DTM) gives a winning strategy / perfect play for chess with 50-move rule.

DTZ50+ (implemented by my tablebases) gives a winning strategy / perfect play both for chess with 50-move rule and for chess without 50-move rule.
