Anyway, you just have to add pawns on the A or H file and you cannot use TBs
anymore, when any human player can see (generally easily) if it is a draw or
not.

These cases are not uncommon. Tiger 12 did not understand them, and the problem
has been reported to me several times. The program lost some games instead of
forcing white to double the pawns on the A or H file and get the draw.
