As for button flat-calling on river, I don't think you can read weakness from that. I would expect him to put CO on the nut low (just as you did), and if he has the A-high flush but not the nut low then most of his profit would be from getting you to call; it would be pointless for him to do anything (like raising) that would make it more likely for him to get HU with the CO for a 50/50 split.

Please correct my thinking if I'm off base here.


Reasonable hands for a turn check-reraise by button (or cutoff) might include:
Nut low with weak flush?
Nut flush, with the expectation of quartering two nut lows?

Reasonable hands for a turn check-call by button might include:
Nut low, hoping to not get quartered.
Outside straight flush draw
made straight flush (would have raised the river, or been the first to bet?)
Nut flush, with a nagging fear of the straight flush
Nut flush, hoping to get it in on the river and quarter two lows
Optimistic and misguided straight with 2nd nut low (very unlikely given the river calls)

I don't think I could make the river call here, but would not rule it out if there wasn't a straight flush possibility here.
