*** TURN *** [:Jc: :Td: ] [:Qc:]
qwandogg: checks
devr: checks

turn question:
Here, if that's Qd instead, do I bet? What about 2c? I think I usually still check back either way, but is that optimal? Can we pre-blocking bet and check behind on the river?

*** RIVER *** [:Jc: :Td: :Qc:] []
qwandogg: bets $0.50
devr: calls $0.50

This one kinda pissed me off. Getting a million:1 on my money, I'm not folding here.

Since I checked the turn, I'm inviting a bluff on the river if the guy called has like T7 or KJ.

river question a:If this player wasn't this bad and bet more, how much can I call?

river question b:If he checks it to me, can I v-bet here? There's still a few hands that can call a v-bet.
