I was told by a pretty solid player that we should be checking our entire range every time we're the PFR, we c bet, and then the flush completes on the turn because of the fact that the opponent has so many more flushes in his range than us. Do you agree? Does this change IP and OOP?

Here's a hand from yesterday that sparked this discussion with the other player:

1/2, 9 handed, $400 effective.

Two limps to hero OTB who raises $15 with 8 7 and only OK reg in BB calls.

Flop ($35): K 6 5. x-$20-c.

Turn ($75): 4. X-$45-raise to $160

Thoughts on the topic and hand? I c bet because of my draw + backdoor equity + rep K, then bet turn because I can't improve, and can x back river because he's very unlikely to lead river.

I don’t think your friend’s advice is necessarily true, especially at 1/2 where people are playing straightforward and we can play so exploitably.

I’d bet the turn a bit bigger and sigh fold now. Betting turn seems fine.

We shouldn't check back this turn, there are plenty of hands we can get 3 streets of value from, Kx may call down, Kx that becomes two pair on the river will almost definitely call us down, things like 54 etc. and of course passively played sets. Not to mention stuff like A6 with an ace of spades.

Always a good strategy to bet/fold against straightforward players. What is he bluffing there on the turn after calling the flop? It's already a wet board so he is not suddenly check/raising a set on the turn if he didn't do it on the flop.

And if he calls the turn and checks to you on a blank river (lets say another 4) then why would you check back with a straight? It's almost clear he has top pair in that case hoping to see showdown, maybe two pair/set which is ready to call your 3rd barrel.

This is where it's important to construct a c-bet range on flush draw boards that do not give your opponent a range advantage when the flush draw gets there on the turn.

Example: I would not cbet T9 spades on your flop. It's a check-call. Then if the flush hits I plan to figure out how to get 1.5 streets of value.

never checking this turn im betting for value

betting blank rivers as well

river on a blank will be an easy bet fold if check raised

I could check back the turn against a "solid" player but that's rare at live low stakes

as played I just fold turn after being check raised

its 1/2 don't level yourself

Whoever told you that is very, very wrong both in theory and most especially from an exploitative POV

No I don't agree. That's ridiculous.

Your BTN raising range should include a bunch suited cards, evidenced by this hand. Perhaps your colleague has a tighter PFR range?

Tough B/F on turn.

Nope always bet for value

Imagine checking the nut flush when we make the nut flush because it’s in our pfr cbet range.

As for this hand, bet fold is fantastic. Likely one of your worse bet bet hands. Next.
