I think I’m folding here all day every day unless I have an extremely strong read, even vs. villains that seem quite splashy. It sucks, but you’ve shown a lot of strength and villain is still making a huge shove. As much as I think ‘waiting for a better spot’ is an extremely poor line of thinking in most situations, it is probably a good idea when we hold a bluff-catcher that doesn’t have blockers to the flush and a stack behind that is still extremely deep compared to the blinds. Even if calling might be slightly +EV vs. range (which I suspect it is not), you’re very likely to have many opportunities to pick up uncontested pots and make some big hands before you are under significant pressure from the blinds.

What was the reaction when you check-raised the turn? How long did it take him to call the 1300? How quickly did he shove the river after your bet?  

I’ve made a lot of mistakes over my career by thinking along these lines. It becomes more relevant if you have a lot of history vs. villain, but unless you are among the top 5% of live tell readers in the world, you are usually better served by only considering stuff like this in very close spots. I don’t think this spot is nearly close enough to spend any time thinking about reactions and timing tells.
