Most likely we're going to see Ax or better that went for a c-r on the turn or checked to do some kind of weird 'induce'.

If they did have a bluff or random air, I expect them to fire out again a lot on the turn.

Even though the FD bricked, I would be mucking this hand as it's a bad spot for them to make a bluff. The B-C-B line at the micros is often value than a bluff.

Any info about your opponent? I could see calling here vs. some players, but by default I tend to agree with @Harvie. Bet/check/bet is rarely a bluff in this spot and since we're blocking some relevant combos of TX even thin vbets often have us beat.

Depends on the player. I would be checking the turn sometimes with Ax because it's hard for you to call with worse. I would then also be bluffing on the river soemtimes too. So it depends on your opponent

1) How wide is their 3b range? (the wider the higher the amount of possible bluffs
2) How aggresive is our opponent and will be bluff us in this spot
3) estimate these two in relation to our pot odds and decide if we should call or not.
