Hello Darkyd10,

Bet the flop bigger! Bet the turn bigger! You are missing TONS of value here. But as played doubt that he is block-betting there with Ax, just hope that he has something like A5 which is blocking.

For the given sample size AF is irrelevant and not correct. He isn't really bluffing there but rather meanwhile had a lot of FDs in his range and maybe even SDs which completed on the turn. Any other hand would have raised earlier or played aggressively.

We need ~25% equity on the river, we get:

Board: 9♣A♥J♣ Q♠ 5♣
       Equity     Win     Tie
UTG    77.78%  77.78%   0.00% { A5s, KcQc, KcJc, QcJc, KcTc, QcTc, JcTc, Kc9c, Qc9c, Jc9c, Tc9c, Kc8c, Qc8c, Jc8c, Tc8c, 9c8c, Kc7c, Qc7c, Jc7c, Tc7c, 9c7c, 8c7c, Kc6c, Qc6c, Jc6c, Tc6c, 9c6c, 8c6c, 7c6c, Kc5c, Qc5c, Jc5c, Tc5c, 7c5c, 6c5c, Kc4c, Qc4c, Jc4c, 5c4c, Kc3c, Qc3c, Kc2c, Qc2c, A5o }
UTG+1  22.22%  22.22%   0.00% { AcJh }

doubt that he is bluffing and nor I don't see him that often to bet this way with just Ax. If we assume he has a wider range then sure, calling shouldn't be a mistake.

Best Regards.
