My Ten blocker is relevant here i think. I have no reads on opponent and not sure if he's going be value betting merged with AAa. For the most part i think he can still do this with his range where the Ace strengthen his overall range a lot .With That said his 3 betting range that possible would have double suited low run downs that pretty much fits very well as bluffs here. His timing was pretty fast as well not sure what to make out of it. Flip a coin and call/fold here??
