Thanks for the post, really interesting hand and position to be!
I don't think we should open this hand from that position.
The circumstances like a small amount of players are left till being advanced and chipleader is on our direct left need to convert our game tight or at least very accurate. 28bbs are a lot, and we do not wanna waste it on unnecessary spots.
Preflop if any 3-bet happens we're folding. If a call happens, not so many kind of boards support us. As you see we even managed to flop top pair second best kicker, yet feel uncomfortable how the action was going. So I support blind stealing attempts at this point which actually have a chance to ever win a showdown.
We came to steal, now opponent makes a 3-bet all-in on the flop. On a board like this, it's either nuts-heavy or a made combination. And neither them is giving us once again a comfortable spot, now we know we will
gambling here a big if we calling this off or almost dead. And keep arriving at the starting point, it all started from a blind stealing attempt, having 28bbs which is such a solid stack to wait and picking up hands, not to push our game to the limits from earlier positions, very speculate hand and even chipleader on our direct left.
