In Dynamic Full Ring Poker: Beyond the Basics, chapter 10: "Understanding Show Down Value" page 120, there is a suggested action in the example hand that confused me.

CO open raises and we 3b. On a KQ3r flop it's checked to us. Author suggests to check here.

Does he places TPTK on a mid value hand? Is he considering this flop so dry?

(you can find the page here)

I think under most dynamics that's a bet(assuming we have air) people generally never check with showdown value, they'd bet their Q9 there, they also don't typically x/c with 99, him checking there signifies to me he's given up on the hand. Of course, I wouldn't assume this with everyone.

What's our hand? (your link doesn't work to me, just has some greek on it)

we have AK. Don't know why the link does not work. It's still working for me.

the point wasn't to give a definitive answer. it's to get you thinking about what the bet actually accomplishes. against fish AK is way more value due to fish calling with many second best hands both preflop and postflop here. against a tighter player, do you get action from second best hands if you bet the flop?

I wrote the hand the author gives because ppl ask for it since they cannot see the page.

I agree on having to bet agaist fish cause they call so much. On a better tight opponent i'd play depending how agressive he is.

I understand though that against some people it would be better to check back and wait to bet on next streets.

Page 120 says we have 77-AA,AK but the flop is QJ2r (not KQ3r unless thats another page). That makes your AK (if you decided thats what you have specifically a semibluff). What a hand is (how strong ) depends on the opponent's range and style of play.

he's talking about the last paragraph in the "The Usage" section

You're looking at the second example of that page (in the "SDV Framework" section) the hand i refer to is just above that.

This is the point. You always have to ask yourself *why* are you betting. Almost always, the answer should be either a) get a worse hand/range to call; or b) get a better hand/range to fold. If neither of these are true, checking is the right play. I think this is what Split is trying to say.

This is a pretty easy checkback when you think about it. I guess it depends on stakes, but anything sNLHE+ this will be a check once you start to think more about ranges for both calling a 3b OOP that will x/c this flop.
