Heads Up NLH hand

OK, I am not sure the play I made can be justified, here is the hand.

Situation My friend and I decided to play a best of 10 series of Heads Up Matches. Game 4, I lead 2-1. Live Game. Heads up. Hero has about 240 BBs, Villain has about 220 BBs

Preflop HERO dealt 6[img]/images/graemlins/diamond.gif[/img] 9 [img]/images/graemlins/diamond.gif[/img] on the button.

Hero calls BB and BB checks

Flop 6[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/spade.gif[/img]

Villain checks, HERO bets 2 BBs (the pot). Villain calls.

Turn 10[img]/images/graemlins/club.gif[/img]

Villain moves as if to check, but then instead tosses in 3 BBs. Hero raises to 15 BBs (raising the pot), the Villain just calls.

Villain checks, Hero Bets 1.5X the pot, Villain moves all in, Hero calls.

Is there anything out of line about my play, something you would have done differently?

Well, since I am not getting any response, let me expand what I am talking about.

On the turn play I became very convinced that he had just made a straight. Once so convinced I very strongly considered laying my hand down. In the end, I decided that I was risking about 8% of my stack drawing to 4 cards to bust him (the 6s and 9s). I thought it was very unlikely that I couldn't get all his chips in the middle if my read was correct and I were to make my hand and felt very comfortable laying my hand down on the river if necessary.

Am I correct in thinking that risking that portion of your stack is justified when the stacks are so deep?

HU, I call this every time. You will see a 6 here usually. All together, this is very straightfoward play IMO. Everything looks standard, nh.

calling the turn is fine when stacks so deep.
