I Raise My Two Pair Flop Checkraiser

[toss]

What reads?

Party Poker 2/4 Hold'em (9 handed) converter

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

Flop: (5 SB) J[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, MP1 checks, MP2 checks, <font color="#CC3333">Hero bets</font>, <font color="#CC3333">SB raises</font>, BB folds, MP1 folds, MP2 folds, Hero calls.

I fear he may have a better kicker. 3-bet?

Turn: (4.50 BB) 8[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets</font>, <font color="#CC3333">Hero raises</font>, <font color="#CC3333">SB 3-bets</font>, Hero calls.

I don't think he has a straight, his flop checkraise doesn't make sense if he had one.

River: (10.50 BB) A[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets</font>, Hero calls.

Final Pot: 12.50 BB

Is this boring and standard?
