Questions

1. Is flop lead good? If I'm raised I'm probably going to push. I don't think I can get my free card if three players check to the PFR'er.

2. Is turn check good? It's HU and I don't see any hand that got scared by that turn card. I can see three hands that villian holds.
a. Set/Overpair - he's pretty ABC so I'd expect a lead or check-raise here from a big hand, but maybe he's check/calling in hopes to get me to spew some more. I don't want to turn my 12-15 outs into garbage if he c/r's me.
b. Flush draw - Check call and checking turn seems typical of an ABC player with a flush draw here. If he has a flush draw, I want him to get there so I can stack him.
c. Other pair (55,66,77,88,99,A10) - This is something that he's 'looking me up' with.' At the point that he calls on the flop and the turn is a brick, would he fold these hands to a bet? Same as before, I don't want to get blown off a hand that can make a lot of money.

3. Is river check good?
It looks like I can eliminate hand #1 from the list here because he's not going to risk it being checked again when he must be sure his hand is good. Hand #2 doesn't call a bet and my ace high is still good. Hand #3 is checking to snap off a bluff, so why give him money.

Overall comments on the hand and thought process greatly appreciated.
