100NL Steal gone bad - tough turn decision

[Cucumber]

NL $1/$1 full ring game, I've been stealing aggressively a lot as a shortstack and generally being a LAG with some success. Villain is 17/4/infinity after 27 hands.

Hero is at the button with $38, Villain on SB with $102.

Folds to button, Hero raises to $2.50 with A[img]/images/graemlins/spade.gif[/img]T[img]/images/graemlins/club.gif[/img], Villain calls, BB folds.

Flop: A[img]/images/graemlins/club.gif[/img]5[img]/images/graemlins/heart.gif[/img]3[img]/images/graemlins/heart.gif[/img]. Villain checks, Hero bets $2.50, Villain calls.

Turn: 8[img]/images/graemlins/spade.gif[/img]. Villain checks, Hero bets $5.50, Villain almost insta raises to $27.50, Hero...?

Are you shortstacking on purpose?

[Cucumber]

Yes, I'm underrolled for the level and trying to build an actual roll, so I had to adapt my play. My good hands earn less but I get less variance overall. Works for me so far after 11k hands - I may be wrong though. I can't play anything less than 100NL because the money in the pots doesn't matter enough to me, so my play deteriorates by a lot.

Also, my good hands get paid less, but get called more often, because a short stack gets less credit for a good hand on average.

It's a genuinely tough decision. You probably are going to have to fold it because the only hands that you beat here are bluffs.

If he is doing this with a worse ace it has became a two pair hand. However, if he is this tight it is unlikely he is calling preflop with many worse aces. So, when he calls the flop you have to put him on hands like FD's and sets or a better ace. You probably aren't going to get value out of a worse hand with a turn bet unless it is a FD. This means that you probably should have checked the turn to induce a river bluff and get to showdown.

He's tight after 27 hands - so this isn't a good read really.
