I think an awful player is calling any pair here 100% of the time.

In his mind, it is too easy for us to have (63) or whatever in the hole , say:
(63)A229(river any 4 7 8 T J Q K).

The villian making a low is meaningless for our calculations (except when he makes a wheel).

I doubt strongly he will raise 2 pair.

Any time he makes a pair we make a bet. Any stronger high we lose 1 (maybe 2, flush, funky set if he raises).

I think we get paid off here the vast majority of high hand battles.
