TT, vs passive line, A and 3-flush on river ($27)

Despite 4:1 odds on the river, there's not much that I beat here, or do pot odds make this a mandatory call given opp's passive line?

I call this in a heartbeat at the $11's - his line is just too goofy.

Well...

Is c/c this flop a bad idea?

I'm usually never a fan of donk betting. I find that in spots like these we get raised off the hand too often with hands we are ahead of. (Overs, lower PP's)

So my plan would be to c/c this flop and lead that turn, if he follows you know he has a hand, and can confidently fold that river.

Was your plan on the flop to fold to a reraise??
I actually never lead in this spot, leak?


Anyways as played I puke and call, and puke some more when he shows me a flush or A-x.

As played I would fold..the A is just too scary..

flop discussion.. let's say you check the flop

1) he has nothing and checks back, you gave him a free card to probably two overs..
2) he has nothing and he c-bets, you called and lead the turn.. he'll probably won't put any more money..
3) he has a bigger PP, he'll bet, then probably go all-in on the turn when you lead..

when you bet here, if your hand is the best you at least protect it.. And give up more quickly if he raises or calls..
