Preflop: Hero is BB with 2[img]/images/graemlins/heart.gif[/img], 8[img]/images/graemlins/club.gif[/img].
<font color="#666666">3 folds</font>, MP1 calls, MP2 calls, MP3 calls, CO calls, Button calls, SB completes, Hero checks.

Flop: (7.00 SB) Q[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/heart.gif[/img], 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(7 players)</font>
SB checks, Hero checks, <font color="#CC3333">MP1 bets</font>, MP2 calls, MP3 calls, CO folds, Button calls, SB folds, Hero ?

Pot is offering 11:1 and me closing the action, but can I really call this a 5 outer? This situation comes up a lot, and I keep wanting to give myself some implied odds, but should I be giving reverse implied instead?

Hero calls.

Turn: (6.00 BB) 2[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(5 players)</font>
Hero checks, <font color="#CC3333">MP1 bets</font>, MP2 calls, MP3 calls, Button folds, <font color="#CC3333">Hero raises</font>, MP1 calls, MP2 calls, MP3 calls.

Did I play the rest of the hand ok? Is the check raise pretty standard as long as the villain was pretty aggressive (he was.)

River: (14.00 BB) T[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">Hero bets</font>, MP1 calls, MP2 calls, MP3 calls.

Final Pot: 18.00 BB.

Any thoughts appriciated. I'm fairly new to 2/4, just got my first 9k under my belt.

By the way, I know this is an easy turn call, but I was more interested in the theory behind it. If the pot would have been exactly 8:1 or even slightly less, would this have been a fold because of reverse implied odds, or a call because I can give myself some implied odds?
