Villain (UTG) is a good TAG, likely the best player currently in the game. He is a 5/10 regular and I played with him @ 5/10 before one time (he is the villain from
http://forumserver.twoplustwo.com/11...-deep-1117493/).
The dynamics is that there are several solid players taking advantage of a couple of fish. I have a tight image and am up, so felt that my image would be clean/good to the solid players playing attention. I don't believe the villain in the hand has ever seen me bluff big.
Stacks: I have $1,200 and villain covers.
Game: 2/5 $800 max @ Mohegan, most people are playing $1k+ stacks so playing more like 5/10 with a number of players who play both games, so thought this forum is the right place for it.
This is a hand where I am really unsure if I played all streets well or most streets poorly, which is rare for me as usually I either know that I played it well/not well or am only confused about one decision. So all constructive feedback is welcome.
Pre-flop: Villain opens in UTG to $25. Bad LAG in MP calls (one of the fish), I call OTB with A

Q

. Mega-fish in the SB calls.
Thoughts on pre-flop: I thinking calling is fine here because I don't think that UTG is only opening such a tight range that AQ becomes completely RIO and I have position, but I obviously don't know his EP range so a case can be made for folding, but with position on one known fish and the whale likely to call very wide, I think the flat is the best option.
Flop ($105). K

SB checks, UTG bets $70, MP folds, I call, SB folds.
Thoughts on the flop: This could be spewy, but the reason I called is that I thought his range was decently strong (e.g. good TP+) so that if I hit my gutshot I had good implied odds. I also thought that I could use position to represent the flush if it came in, and thought he was definitely a good enough player to lay-down a good portion of his flop betting range if hearts came in.
Turn: ($245): K

Villain thinks a little, looks like he is taking chips to bet then checks, I take a bit of time and bet $225. He quickly calls.
Thoughts on the turn: I hit gin, it's disguised and I want to try to get max value before a scare card comes.
River ($695): K

Villain checks, hero ??
Questions:
1. Is floating flop with my plan as outlined bad/spewy or a decent play?
2. What is villain's range after he c/c's turn?
3. What is his range after he checks river?
4. Should I value-bet and if so how much? What is the range that calls me if you think I should value bet?
