Looks fine. Calling the 3-bet in position against someone who seems to be capable of 3-betting light and could well be squeezing is cool. Checking the flop and leading turn actually makes our decision easier when SB shoves river because we've underrepped our hand, whereas if we were check-raised on the flop or shoved into on the turn we would probably be a little stuck for ideas. As played, SB's range is basically monsters or air, and he surely would be looking to bet the turn with a monster with a view to getting it all in on the river.

So yeah, looks good from here. I happily call river expecting to take this down at least two-thirds of the time.
