Strange 77 hand against donkish bettor

[Little Fishy]

I'd fold that flop... I'm assuming it was .10/.25 blinds and there's $1 in the pot...

if you're intent on playing it then you really have to raise that turn... the best you can hope for is that he has 45, AT, QT or JT and that he'll release thinking you have a king...

however if he really is that donkish then he'll call your turn raise and check call the river with his T... i say you play your 77 for set value and let it go when it could easily be dominated.
