This comes down to which hands that call the turn will fold the river.

the flop checks say that your range is capped. Now, I am inclined to believe flopped flushes bet the flop from the button when checked to. He is on the button. For this reason I want to greatly discount made flushes from his turn calling range, except for maybe the nut flush or 2

I don't know.
What else would the BU bet on the flop? doubt the bastard has KK. But, he would probably bet 99 and 66. Or maybe XR the turn with them, but more on that later.
On this board, he could check his straight draws.
He could check all of his two pair. This seems believable. He could check all PPs, including those with a heart.
He could check rando single hearts and of course his air as well.

Everybody folds except the button who calls. Now this is the decision point. Which hands call?
-Straights
-Straights + heart redraw
-Pair + gutter
-Pair + gutter + heart
-two pair
-PPs w a heart
-Sets
-Ah
-Flopped flushes
The river isn't really a brick. I guess you can count the combos and decide which parts of his range fold for your size and come up with an answer. At this point I've gotten lazy.
When I started writing this I thought it might be fine, but now I don't know. Sometimes all the 6
7
will call the turn and fold the river, for example.
