I have not been playing much full ring cashgames(or 6-max) in a while so im really lost in some spots.

Heres one:

PokerStars No-Limit Hold'em, $1.00 BB (7 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

UTG ($98)
MP1 ($104)
MP2 ($90.50)
CO ($159.80)
Button ($95.05)
SB ($51.80)
Hero ($100)

Preflop: Hero is BB with J[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">MP1 raises to $4</font>, <font color="#666666">4 folds</font>, Hero calls $3.

Flop: ($8.50) 6[img]/images/graemlins/spade.gif[/img], 6[img]/images/graemlins/heart.gif[/img], T[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>

Hero checks, MP1 checks.

River: ($20.50) 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">MP1 bets $15</font>, Hero folds.

Final Pot: $35.50

I think this was one of my first hands at this table, so this is readless.
