Button vs big blind flat on monotone flop

To answer your question, this seems fine to me. If we have to check back more flushes I imagine the straight-flush draws (56 57 67) are a good candidate since they kill 1 or 2 outs of higher diamonds (even though that a bet is again super good). But this is purely theoretical and tbh it seems useless
I cannot imagine Im ever checking back a flush on the flop. I prefer betting all value hands and possibly overfolding to check-raise. And when we get check-raised we can then balance too - calling draws, high flushes etc...

Yeah, i get where you are coming from with just overfolding check-raise since we will probably miss more value when checking our strong flushes vs majority of players.

Thank you for the insight and reply!

I think in theory you bet some flushes, check some flushes. You bet your sets. And then you bluff with some off-suit stuff with one diamond...
But at the tables I would probably cbet small with a wide range.

There is what I got with a solver. Bet 37% of the time, check rest.

This is really counter-intuitive @La55i, damn...
Are those suited hands flushes or all suits?

Ummmh

If I remember correctly this was like throwing a dice and deciding whether to check or bet ♦
With those suited hands we sometimes bet the flushes and sometimes check them.. And sometimes bet suited hands that do not have a flush
From those suited hands 1/4 has a flush. So if you look at 69s and 67s for example, those are over half blue so we are betting other than just flushes.
And when we are betting flush combos it could be like we bet a specific combo only 80% of the time.

I could actually tell the software I want to be betting always with nut flushes and sets and see how it balances that out.. But don't have time for it now so maybe tomorrow
