TPTK Facing Bet and Raise

[Chicos75]

4.40/180
My plan was to check raise one player all-in but now what?

PokerStars No-Limit Hold'em Tourney, Big Blind is t100 (8 handed) internettexasholdem.com

MP2 (t1388)
CO (t2930)
Button (t6275)
SB (t6433)
Hero (t1570)
UTG (t2684)
UTG+1 (t2930)
MP1 (t5140)

Preflop: Hero is BB with A[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/club.gif[/img].
<font color="#666666">3 folds</font>, MP2 calls t100, CO calls t100, <font color="#666666">1 fold</font>, SB completes, Hero checks.

Flop: (t400) 4[img]/images/graemlins/diamond.gif[/img], 9[img]/images/graemlins/heart.gif[/img], 6[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, Hero checks, <font color="#CC3333">MP2 bets t300</font>, <font color="#CC3333">CO raises to t2830</font>, SB folds, Hero ????

I don't like your plan. A much wider range will call bets than will bet and/or bet/call.
