QJs, facing preflop raise

[Boolean]

After whoring the bonuses at the Party Skins, I saw that PokerStars has a reload bonus. I ask myself later, why am I playing .50/1.00 to clear a bonus at PokerStars? But I digress.

Reads: preflop raiser is a TAG. MP3 is a LAG.

I have a backdoor flush draw with 2 overs. The TAG is raising about 10% of his hands, so I'm not going to give him credit for a pocket pair that beats me. Still, in this raised pot with all of these cold-callers, if I'm going to continue, I'll have to protect my hand. So I bet into the preflop raiser. Good play? No?

Turn: (8 BB) 2[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
Hero checks, <font color="#CC3333">MP1 bets</font>, <font color="#CC3333">MP3 raises</font>, Hero calls, MP1 folds.

I pick up my flush draw and it's 5:1 to me to call. Fine.

River: (13 BB) 6[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">MP3 bets</font>, Hero calls.

Easy call, playing the board for the straight.

Final Pot: 15 BB
