POSTED Dec 08, 2018

Nick Johnson explores the topic of flop c-betting on paired boards BTN vs BB. Weighing the pros and cons of betting different kinds of hands in PLOCalc, Nick gives you a number of different factors to think about in these spots.

Great video, also emphasized a lot of "standard" concepts of unblocking and blocking stuff, which is always helpful when constructing ranges.
I was always betting very merged in these spots, I will adjust now and see what I encounter.
You mentioned a few times, that betting too merged is bad, because against a decent c/r range, we fold too many hands that push decent equity.
Against a population that underbluffs immensly, isn't it a good idea to bet merged and choose a smaller sizing?

Yeah, if you find that they are more straight forward and under bluff significantly, then we can adjust as you stated. It's more from a theoretical perspective that we should consider polarizing more and then adjust in practice accordingly. Great point and thanks for the feedback on the video!

I do feel that population under-bluffs significantly on paired boards as the bb caller, and getting into that a little deeper I think we find hands that likely should be incorporated into a balanced x/r range x/calling the majority of the time. I believe this is for two reasons. A) people believe their "board locked" hands constitute anything with a full house or when the trips are the over-card, any good trips and thus believe they will lose action raising and are "trapping" by calling and B) over-estimate the range advantage the PFR has on these boards. Due to this I think we see a lot of players using a merged betting strategy with a low amount and an extremely high cbet%, and in many games where that isn't being defended against correctly I think this is the best play. I think I'm guilty of over-calling here as well.

Nick Johnson so because of this I'd like to see a video on the opposite angle, how we should be attacking a merge strategy that population seems to be incorrectly over-implementing. What hands actually make up the call portion of or range vrs the value raise and bluff/semi bluff portions?

I think a video that takes a look at how to find bluffs on turns and rivers would be quite interesting.

Hey stianchrister, I'm always listening for suggestions on video topics, so I appreciate it. Are you looking for essentially just a general video covering what villain's bluffing range could look like on the turn and/or river or were you looking for something that was related to this video specifically?

stianchrister 6 years, 3 months ago

Nick Johnson Not just what it could look like, but what it should look like. I'm thinking some real range construction stuff with some extracted heuristics about how to construct our ranges and be reasonably balanced in a spot, especially as a hand goes over multiple streets.

--Edit--
It would be interesting to see if we could find some GTO-approximate heuristics from solver insights about how to construct our ranges on common board textures and so forth.

Sure, we know it's better to bet polarized than merged in PLO, but on KK5, there's a lot of hands to pick from because we whiff a lot on that board. Which hands are better for bluffing? What about other board textures?

Can we see any patterns from the solvers and get some heuristics from it for a handful of board textures?

I think that would be a goldmine.

hi , can you say how much the opening raise is ? do you calc rake ? .. im playing games where the normal is 3,5x and high rake , how is bb defending in that environment ?

Nick Johnson 5 years, 11 months ago

Pot sized opening raise and if you are playing in a high rake environment, then I would say start to tighten it up and not worry about defending too wide if that is the case. Something like 37% defense (27% call, 10% 3B) seems reasonable from what I have in my notes. If rake is even higher than what is standard for say a PLO50 game, then tighten it up a little more and probably 3B slightly more often.

Hi Nick,
So from what I learned I believe a decent chuck of both players ranges are very strong therefore flop aggression should go down. Does that mean that bet size should go up when we bet as the IP player (because we are polarizing our range)?
Enjoyed the lesson! Please correct me if I've interpretted anything wrong.

Nick Johnson 4 years, 8 months ago

Hi TomF,

Thanks for the questions and sorry for the delay. Flop aggression is down a little in general when we are c-betting on the BTN simply because our range is at its absolute widest, so our range advantage a lot of the time isn't actually all that large if it exists at all. Quite different compared to when we open UTG and get an ace high or broadway heavy texture right? In that spot we have less air and more value, so we likely are supposed to take aggressive lines more often. Throw in the fact that we are talking about specifically paired boards and we will become naturally a little more polarized within this dynamic.

When we become quite polarized it does often make sense to size up (especially if you have the polarity advantage meaning more nutty combos in your range), but when on the BTN vs the BB hero will very often not have a polar advantage actually on most paired textures. We have a slight range advantage, but due to the lack of polar advantage and the fact that the board texture encourages us to size down I would say sizing up early would be a mistake.

You may ask why does the board texture encourage us to size down if we are a little more polar here? It becomes pretty easy for villain to play his range if we size up too large. Too much of his range can correctly fold and he often will only be encouraged himself to continue with the top of his range. By sizing down we get more value out of more of his range and we also can bluff for less. It makes sense to consider this strategy/sizing on the more static and/or locked down textures such as paired boards, monotone boards and 3 card straight boards.

Hope I answered it all for you and feel free to follow up!
