Again, you have given us no reads to work with.

It looks like he puts YOU on AK
when he raises the non-heart turn, his
c/r looks like KQ or even 99; maybe QQ, KK - which
is less likely due to no cap pf.

The turn c/r is very strong here due to the strength
you have already shown in the hand. I would put you
behind or drawing dead frequently (again with no reads).

If you agree his turn c/r is strong and he doesn't bluff like
this the correct fold may be on the turn. That said, TPTK
is too damn good in a Micro game to fold with any
certainty. I might see the river, make a crying call and notate
the play of the SB for later hands.

Tough one kiddo...
