($11) Push AQo against 3x raise?

[gulon]

BB was very tight and did not defend blinds. CO was TAG, not much else of a read on him.

I folded this in the game. On review, I wondering this could have been a PUSH?

Assuming that BB folded, if CO was stealing then his calling range would be tight and my FE + win% would be high.

If CO raised with a smaller range TT+/AQ+ then I have no FE and his call% and my lose% would be higher.

Since my read was that he was TAG I folded. However, at 75/150 everybody is also motivated to steal blinds. Am I giving him too much credit for good cards here? Mitigating between a tight player's tendancies and their motivation to steal is a tough one that affects EV significantly.
