My thoughts:

- Flop cbet for value/protection vs worse Qx, pairs, and draws.
- Turn check for pot control and having some strong TP hands also.
- River call vs Qx or missed draws.
- Playing Zoom, so no reads beyond basic HUD stats.

Questions:

1. Should AQ barrel turn more often?
2. Is this river call too thin?
3. Whats your play?

Thanks
