I think I'd fold flop. Until that point you've put 6c into the pot, so putting another $3.36 in when we're always likely to be behind I'm not a fan of. I tend to laugh at villain to losing all value on his hand and just fold.

Villain's large overbet donk will normally mean a decent hand he's scared of the draw with, so Ax or a set (or even a randomly played flopped flush with small cards but far less likely).

I don't know if you use Pokerstove, but this will help you look at hands like this where you can type in your starting hand, how the flop comes out, and a likely range you can put villain on given the action (so here it would be 77, 88, AA, A7, A8 etc). It will then tell you how you fare against that range and from the equity calculation you should know whether stacking off here is +EV or not.

Hope that helps

dont like it, I think were never ahead when we get it in.

thanks for your answers :-)

i looked it up in pokerstove and only got 35% equity against his possible range. seems like a really bad allin..
