To counter these donkbets I try to play my overpair and top pair hands similarly. This involves calling the flop, bet/calling the turn, and bet/raising the river.

With overcards I mix it up between raising the flop and checking the turn, and calling flop & folding the river UI. This is because I've found most donkbets been from passive fish who have hit a pair on the flop and bet out the flop to build a pot, and then calling down regardless of what I do.
I'm only playing 2/4 so I have no idea how effective/ineffective this is in the long run.

I've run into very few players who have bet out the flop, called the raise, and bet out the river (after I check behind the turn) without some sort of pair.

What lines have you tried against the donk bets?
