Luke Johnson

POSTED Mar 01, 2024

Luke Johnson plays a session against the bot in an effort to replicate in-game decision making for 3-bet pots SB/BB vs BTN. This trainer session sets up the following part where he will explore some of the more difficult hands and gather any heuristics to implement going forward.

When stabbing the BTN vs a SB or BB check, are you mostly using the 1/3 sizing, then using the 1/2 sizing only on more polar boards? Are you ever using the 2/3 sizing? I know the 2-broadway boards tend to be more polar stabbing spots, are there any other board types that you would use a polar stabbing size on?

Luke Johnson a year ago

Correct, and yes sometimes sizing to 2/3p, but rarely.

Polar boards generally require 1/2p or 2/3p, there are some, though, that require polarisation but via a b27 stab size, like Axxs (low low kickers) boards OTBvsBB. Inversely there are some boards that require depolarisation, however for a bigger size, like 322r -- effectively the very low disconnected textures where your low PP's that want to bet are allowed to size up.

As for your question specifically, in ring there aren't any others, outside of some weird spots where OOP is supposed to range bet but misses it, like Q55 COvsSB.

For me I was playing A, K, or Q high boards as 1/3 or X, so as the PFC, I would still use this 1/3 probe / float bet size on the flop. I wasn't aware we are supposed to use more 1/2 or 2/3 on double broadways as the PFC. Being we are at a set disadvantage I didn't think we would want to put in a lot of money.

As the 3 bettor I am playing A-Q high boards 1/3 or X. J-T high boards being mixed between 1/3 or 2/3 size being a punching bag approach. 9 high or lower boards playing 2/3 or X.

So my take away would be 1/3 or X on A-Q high still unless its double broadway? Then its 2/3 or X as the PFC? matlittle Luke Johnson

RunItTw1ce Most common stab size for this spot (by far) is small (25-33%). You can even hyper-simplify your game-plan and ONLY use one small sizing here across all boards without much loss of EV.

From there you can then add in a 50% sizing for more polarised boards. From my research the main boards that want this sizing are:
Ace-Broadway-X two-tone or rainbow
Broadway-Broadway-X two-tone

There are a few other uncommon ones you can find if you look hard enough:
322r that Luke found
Spots where OOP misses a range-bet that Luke mentioned
Some monotone boards like AXX, Broadway-Broadway-X but these are a mixture of 33% and 50% in preference, hence the EV across these board types is very close for each sizing, and not worth complicating your strategy to mix in 50% here and there.

The stack to pot ratio is not big enough in a 3BP 100bb deep for us to be too worried about nut disadvantage when picking our bet sizing. Also consider that our opponent will be able to get their stack in easily vs any stab sizing anyway across 3 streets.

As matlittle suggested, playing 1/3p only as a stab isn't a terrible approach. You won't lose too much EV. However, if you want to mix sizes, then these heuristics are too simplified; we should not just blanketly group A, K and Qhi boards all together. There are many more complexities within. Aggregations are a great way to sift through the nuances efficiently.

Great comment matlittle

If you go about this approach, it's imperative you still aspire to UNDERSTAND what's going on, as per the ranges, instead of relying on the heuristics. E.g. HU 3BP plays a lot differently. If we simply followed the above guidelines, the transition would be difficult. However, if we were always trying to 'live solve' what's going on, we could perhaps even work out the new heuristics without the presence of a solver.

That + the boards that typically warrant a big size are high (like AKx) where we have many tp's with low kickers that are relatively strong, but do not need to bet, enabling us to polarise a little further.

matlittle a year ago

Also I'm curious as to why you skip all the monotone boards? Do you use other sims with different sizings on those boards? To me they are some of the trickiest boards to master with some of the biggest mistakes made on them, so studying those would be of high value.

matlittle a year ago

Thought that might be the case, would be cool for you to fire up the monotone sims at the end of a similar future video and go through a couple, would be interesting to hear your heuristics on those board types

Yes definitely will cover for the future. I find them more fun to study as they are super challenging and incredibly eye opening.

Definitely like the format.

  1. 5:30 table 1 55 you said you don't want to depolar your range. In this spot my first thought was bet size between 80-100% pot. Is that too big? Is 50% a polar size for you?

  2. 8:07 table 2 87 you said your sizing here is block. My thought was opponent is playing a polar range of betting and checking as such we would want to be more polar.

  3. Same hand, if we do block, if the board were rainbow, do we start using bigger bet sizes since the turn doesn't have the chance to affect equities as much?

  4. Same hand, we bet turn as a semibluff/value bet I assume, but despite our spades the river seems like a bluff spot to get opponent off pairs under the ace which we unblock.

  5. 10:47 table 2 aa you said connected broadway boards you can 2/3 pot but semi connected low boards you can pot. Why is that?

  6. 22:14 table 1 opponent has qjdd. Is that ever a jam for him over your turn raise or is the fold equity just not there for him?

  7. 27:10 table 2 kj, does having the spade affect your turn betting frequency given that we block more of his draws?

  8. 30:25 table 2 aj, will you follow through on a lot of rivers, or will it be primarily spades or broadways?

Thanks!

Glad to hear SoundSpeed :)

5:30 table 1 55 you said you don't want to depolar your range. In this spot my first thought was bet size between 80-100% pot. Is that too big? Is 50% a polar size for you?

As IP, yes 80-100% is a little too big here. Polarising is required, but not that much

8:07 table 2 87 you said your sizing here is block. My thought was opponent is playing a polar range of betting and checking as such we would want to be more polar.

We are polar, but still use block. I actually got this slightly wrong, though, see . As you can see, the the idea of block/check, whilst still being polar/selective with betting hands is good on A85s, but not on A96s.

Same hand, if we do block, if the board were rainbow, do we start using bigger bet sizes since the turn doesn't have the chance to affect equities as much?

We'd want to size down more, as we are allowed to vbet thinner with some underpairs/9x on the rainbow version. This is due to OOP also doing the same.

Same hand, we bet turn as a semibluff/value bet I assume, but despite our spades the river seems like a bluff spot to get opponent off pairs under the ace which we unblock.

Yep turn is a semibluff. Great thinking OTR! I ended up missing this one completely

10:47 table 2 aa you said connected broadway boards you can 2/3 pot but semi connected low boards you can pot. Why is that?

On these low textures our 3b range almost completely misses the board, so we end up with an option to go PSB with our overpair region, usually using the lower (TT JJ) ones first.

22:14 table 1 opponent has qjdd. Is that ever a jam for him over your turn raise

Yeah shoving will also be good for him. Try not to think about

or is the fold equity just not there for him?

IN THEORY there will always be enough fold equity in these spots.

27:10 table 2 kj, does having the spade affect your turn betting frequency given that we block more of his draws?

Yes. I'd actually want to bet more with it, as I'm wanting a fold when I bet, not a continue. Strong hands, like JsTx (I am 3betting JTo pre in this config) would prefer NOT to have the Js.

30:25 table 2 aj, will you follow through on a lot of rivers, or will it be primarily spades or broadways?

Yes, I'd bluff only on good cards for us as I have other hands to use first as bluffs on blanks. Good cards being spades/broadways, but also Tx / perhaps 8x, too.

Thanks!

Welcome as always <3

9:00 with 8s7s on Ad9s6s-7c if you face a cbet or turn barrel how likely are you to raise and push your equity vs realize your equity by calling? If we think villain has AJ+ here are we ever "gambling" with our equity or just trying to realize all of it? Not sure if low stake live players will ever 3B and fold AK-AJ here if we do choose to raise.

10:00 AsQs on k32ss-3-3 facing a X-X-66 line I was thinking fold on the river. Your thought was call then shove because you chop with A5, so you are bluffing him off some chops. Folding didn't even seem to cross your mind at all. Is this because you bet most of your QQ-44 hands for 1/3 on earlier streets, so ace high is just high up in your range?

Good question RunItTw1ce

Ultimately it'd depend on the bet size I face. I am more likely to call with equity that doesn't positive blockers. 87 here blocks some relevant hands for OOP, so I could see myself playing aggressively vs bets/raises.

With two spades in my hand and two spades on flop + XX XX line, my spades typically unblock bluffs and block continues (like trappy AsK, AsA). If you change only slightly one of the three described dynamics, everything may change. It's quite a knife-edge strategy.

10:50 Usually on 9 high and lower boards I'll go 2/3 or X. I was thinking AhAx hands want to go 2/3 and maybe we can use 1/3 when we double block the flop suits. So it splits our AA combos 50/50 with 1/3 or 2/3 size. I am not sure how to balance checks with this method. Maybe just 2/3 when you hold a heart and X without and don't use 1/3 at all?

Luke Johnson a year ago

AhAx vs double blocking AA's is a good find, nice job.

I typically only split between b70 and check here, without including a smaller size. I would recommend you to do the same on this board specifically, as b33 doesn't seem all that worthwhile for the added complexity it brings.

Then we can roughly use your system to split between betting and checking.

Luke Johnson a year ago

I finally got one right you agree with ;-) I'll play AhAx as B70 and the other 3 combos blocking the calling range as checks.

Hahaha, I feel like I must be a very strict teacher, sorry!

That strategy sounds a lot stronger (and easier) than your previous one

13:24 A7d on AQ2ssd-9x-9x ever consider turning A7d into a bluff to get villain off chops? Similar to your AQss hand on the K3233 board at the 10min mark. I feel like when SB plays XC-X-X you hardly ever lose here, so I would want to value bet top pair here even though our kicker doesn't play. Not sure of the sizing though. If we want to go big to get villain off a chop? Or we go small and target more KK/JJ/QX hands?

28:25 As4s on J32dd-6ss when you only have a min raise left as a bluff facing a double barrel, how do you pull the trigger on combo draws? Feels like zero fold equity here and I just want to realize my equity.

In hindsight his A7dd seems poorly played OTR, oops! I don't think we need to try and get villain off chops as much as we just want to bet 2/3p vs their bluffcatchers.

BLOCKERS!

It's all about blockers here in the tiny SPR :)

I can promise you bots and good regs have folds here. What do you expect humans to do with all their low fd's/KQo AQo with good suits?

RunItTw1ce a year ago

I enjoyed the format, but wouldn't mind a full 60 minute video where you have time to review the hands at the end of the video. We are left waiting a couple of weeks for the results. Also hopefully you figure out how to see opponents hole cards on non showdown hands.

Luke Johnson a year ago

Thanks mate. Yes I 100% agree with you on including the review in the same video, apologies for the inundation of cliffhangers, lol. Will do for future videos! We will see villains cards in the review.
