Hand1:
Villain is 60/30/1.2 after 80 hands. His WTS is 36%
Stacks:
UTG ($764.25)
Hero ($1416.95)
CO ($149.08)
BTN ($714.00)
SB ($1562.98)
BB ($389.10)

Pre-flop: ($9, 6 players) Hero is UTG+1 [Js]
1 fold, Hero raises to $21, 2 folds, SB calls $18, 1 fold

Flop: [4c][5c] ($48, 2 players)
SB checks, Hero bets $35, SB calls $35

Turn: ($118, 2 players)
SB checks, Hero bets $85, SB calls $85
I decide to semi bluff here again, I have 6 outs if he decides to not fold his PP, if he has FD I have a very high ace so I actually VB may A high.

River: ($288, 2 players)
SB checks, Hero bets $165, SB calls $165
Now I decide to fire river since there is a missed flush so there is a better chance he might look me up. Good/bad?

Hand2:

Stacks:
UTG ($879.05)
CO ($1204.45)
Hero ($603.60)
SB ($1221.00)
BB ($600.00)

Pre-flop: ($9, 5 players) Hero is BTN [4s]
UTG calls $6, 1 fold, Hero raises to $27, 2 folds, UTG calls $21

Flop: [6d][4c] ($63, 2 players)
UTG checks, Hero bets $50, UTG raises to $100, Hero calls $50

Should hero fold here? I do have gut+ FD. However, it is likely that he will have air here some of the time, some of the time weak PP that has me beat but will not pay me off. It is also likely that he has set so that my reverse implied odds suck if i hit trips or 2 pair(2 pair means he could have a str8 :S)
