75/150 SH. VEGAS. 66.

[flawless_victory]

its late. game is 5handed. sam grizzle is button. he just got in the game and is making it quite good. hes extremely active (playing every hand)... i am sb. i have been pretty reasonable with pre starting hands and kinda hyperaggro... it has been commented on more than once. the bb is this northwest guy who is really passive. he is prob a small winner in a full 75 game, and a big loser in a short game...
sammy openraises button (top ~85%), I squeeze off 66 and immediately sling about 14 chips... dealer returns all but 9, BB says "im game" and calls, call. i bet dark.
flop 6 [img]/images/graemlins/club.gif[/img]5 [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/diamond.gif[/img]
bb calls, sammy raises, i threebet, coldcall, fourbet, i cap, coldcall, call.
this takes about 4.2 seconds.
turn is 7 [img]/images/graemlins/spade.gif[/img]
<font color="red"> i check </font> , check, sammy bets, i call, BB calls.
river 2 [img]/images/graemlins/heart.gif[/img]
check, check, bet... i call...
what do you guys think of my play? what do they have? should i bet turn, checkraise turn, bet river, checkraise river? should i call the turn fourbet and go for the turn checkraise in case BB has a gut shot?
