Button (t1500)

UTG+1 (t1500)
MP1 (t1500)

CO (t1500)

Preflop: Hero is MP2 with A[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
<font color="#CC3333">UTG raises to t40</font>, UTG+1 calls t40, <font color="#666666">1 fold</font>, Hero calls t40, MP3 calls t40, <font color="#666666">2 folds</font>, SB calls t30, BB calls t20.

Should I raise this pot here? I didn't want to get too crazy on the first hand.

Flop: (t240) Q[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/diamond.gif[/img], 2[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(6 players)</font>
SB checks, BB checks, <font color="#CC3333">UTG bets t40</font>, UTG+1 folds, <font color="#CC3333">Hero raises to t140</font>, MP3 folds, SB folds, BB folds, UTG calls t100.

How is the size of my raise here?

<font color="#CC3333">UTG bets t200</font>, Hero calls t200.

Should I raise the turn?

<font color="#CC3333">UTG bets t1120 (All-In)</font>, Hero calls t1120 (All-In).

Im putting this fellow on a weaker ace or a smaller pocket pair (JJ-88), do you make this all-in call?
