I don't remember the details, but, how much to adjust against idiots?

[bholdr]

So i was playing a little paradise 4/8 hi-lo, there were a couple really horrible players in the game quickly going broke, and this hand comes up: I'm dealt [7[img]/images/graemlins/diamond.gif[/img]A[img]/images/graemlins/diamond.gif[/img]]Q[img]/images/graemlins/diamond.gif[/img]

the donks each show low cards, and a weak-tight player limps with a K[img]/images/graemlins/club.gif[/img] showing.

on fourth i caught perfect- a low diamond, and each of the donks also caought wheel cards. the action was capped, with one of the donks on one end of it and me on the other.

I paired off on fifth (7s, i think), the donks caught bricks, and the WT got another club- he bet, all called

On sixth, I made a decent low draw, the donks got more wheel cards, and the WT got a fourth club, and he's playing strong, so i had to assume his flush was made , but i continued on, with a huge pot, draws to an AQ flush, and seven low, but all i manage to make is a 8-7 low.

The bettor (with the obvious flush) bets on the river, behind me are the two donks- each of which has three wheel cards showing. pot is $168- $8 to call, possibility of jamming is about 20% i'd have to geuss

Do you fold, or call with the worst possible low?

obviously, since I'm making this post, they didn't have lows, but i feel that long term this fold makes sense. of course i have notes on both of the fish now.

I geuss my real question is this:

How much are you willing to adjust your calling-for-value standards against really weak players? far enough to call with an 8-7 low in the above situation? how about calling down river bets with naked big pairs?
