In general I think it's too optimistic to expect folks to fold a decent flush. You also can't really rep a FH as hard when you don't raise flop. And I don't think having the Q really blocks a significant # of his house combos.

river jam looks like an interesting idea, till you actually start doing them and realise that

a)his river betting range is just way too strong. And I dont mean "his hand is nutted", I mean "He thinks that his hand is nutted", which is a very important distinction when you're planning to bluff him. We both know that As is a really bad bluffcatcher versus your jam, but thats simply irrelevant if we want to bluff.

2)You will get called by As a lot

3)You will see boats a lot.

Basically you're planning to jam into uncapped ultrastrong range with literally zero bluffs, where even the middle of that range can be perceived as nuts by half the player pool and you might get him to fold. Might not. You know that you're getting called by boats. The fact that we dont block anything is basically irrelevant.

Not a good plan imo, just fold

A shove here would probably work against a competent opponent some of the time. Probably run a CREV sim to see how often, giving him calling range of all boats and A/K flushes. However generally what limp limpson said is correct. You'd have to have history or a soul read for this to really generate expected value
