And prf raise from ep/mp kto/qjo but no 76s87s ?

When you open UTG, you're more likely to face a 3bet than you are to face a call (in GTO), so the solver chooses hands that have stronger blockers against 3bets, such as KJo, K6s, QJo etc.

If you get rid of the rake and open to a small size then ppl call more, and the solver starts to prefer hands that do better when called like 76s etc.

What do you think about 3bet ranges from BB 3bet vs every position? Why it prefers 3b f.e vs ep/mp AQo /Kqo then AQs /Kqs

Huh? I think you're asking why EP folds the offsuit hands against a 3bet?

AQ/KQ are both very near breakeven against villain's 3bet range. The suited hands realize more equity - they can more easily continue under pressure as they can draw to a flush. This improves implied odds too. Additionally, if you call all your offsuit hands, then your range becomes more exploitable on many boards.

The evidence is very statistically significant and reported from multiple sources. I've read that multi-tablers tend to get underdealt CO spots, whereas people who single table tend to be overdealt those spots, likely due to a flaw in their seating script.

If you play on party, I encourage you to post your total hands by position. Even if your sample is small, the smart folks here can run simple statistical analysis to see if it's significant.

You can calculate it manually with the equities. But just looking it up:

AKhh is indifferent, and AKdd is a -1.71 call, (out of a total 201bb pot). In terms of human-level accuracy, these are all indifferent.

I'm just wondering why in this solution AdKd is a pure fold where as AhKh is mixed? Is it because AhKh blocks more AQs and KQs combos.

Go into their range, filter for all in, change from "strategy" to "range".

Now filter by suit, then tally how many bluffs and value combos you block with each suit of AK.

AKhh unblocks KThh bluffs and blocks AQhh value. They both block the same amount of KJ. It's extremely marginal though, only about a 1% equity gain for hearts.


The above process is pretty much the universal procedure to "why is X blocker preferred" kind of questions.

Post villain's shoving range

Sept. 9, 2021 | 11:10 p.m.

I don't think it's a good call in practice. 4bets IP are too overpair-heavy in reality.

Facing the flop shove you have a pure bluff-catcher. Do you think half of villain's shoving range is ace-high garbage? Because that's about how often they need to be shoving A-high garbage for your call to make sense. Even at midstakes I seriously doubt it.

Comment | fishcheckmate commented on 50z JJ squeezing

Seems fine. You raised over an iso so technically not a squeeze, but still a fine hand to raise with. cbetting flop is reasonable. The turn strat depends on the context.

Don't reinvent the wheel, there are tons of free, high-quality solved preflop ranges out there. +1 for free GTO Wizard ranges.

There's nothing wrong with trying to invent your own stuff, but that 3b range is horrendous. You're completely overbluffing. You're mixing in a ton of garbage that shouldnt even be played, medium hands that don't belong in a super polarized range, and not enough value in general.

The main factors to consider are position and linearity.
If you're out of position, anything less than a 75% raise is almost always a poor choice. If you're in position, anything larger than a pot-sized raise is almost always a poor choice.

Use smaller sizes when your range is linear. If you only raise/fold from a certain spot, then you'd use a smaller size as your range is top-down and you want to get called by worse. If you're using something polarized, then you're aiming for fold equity and need to size up.

For example, modern preflop theory shows that in most raked games, 100bb deep, the optimal 3bet size in the BB vs BTN 2.5bb open is about 12-14bb, as we're out of position and are supposed to go polar. However, something like a HJ 3bet vs a 2.5bb UTG open is gonna be closer to 7bb, as we have position and a purely linear range.

3x IP and 4-5x OOP is a good enough rule of thumb if you want something simple.

This is always going to come down to extremely delicate blocker effects. Observe which value/bluffs you block and unblock in SB's river betting range with the Ad.

Don't get too hung up on this. The exact strategy by the river is gonna be hyper-sensitive to your inputs, your tree, the rake structure, the assigned preflop ranges, the possible raise sizes, etc.

Here's a high-resolution sim from GTO wizard 50NL solutions, which have between 6-19 sizes per node. This sim assumes SB opened for a normal 3bb size and not the funky 2.5bb size.

All you need to take away from this sim is that A7o is indifferent - a 0EV bluff catcher.

Comment | fishcheckmate commented on playing deep

Flatting JJ is fine 200bb deep, can also 4b.

As played, go for more value in general.

As a rule of thumb, It is almost never correct to quarter-pot the river in position - halfpot minimum and usually higher.

this kind of bet,2 into 100,how will u guys deal with it?

Just treat these microbets as a check. Call hands you would normally check, and raise hands you would normally bet.

Pio uses less RAM than GTO+. They also have a hidden setting in their scripting that allows you to cut the RAM requirements in half, in exchange for slower processing.

I recommend going even smaller, maybe 25%.

The thing to understand is that when you bet small, you are getting a better price on a fold equity.

The small bet is used when villain will have a hard time defending wide enough. For example, If you bet 25% pot on say, JJ7r, villain needs to continue about ~80% of the time. The average player will drastically overfold compared to this benchmark.

When a hand mixes between actions those actions should have the same EV. So if it's mixed between folding/something else then it's 0EV regardless - that's a hard principle of NE.

The only reason it mixes is to avoid exploitation. Typically the exact mixture is gonna come down to subtle blocker effects.

0 money in the pot

Change your parameters, this right here will break your solve. You need some money in the pot to incentive betting.

The solution will be to bet only the nuts and then they fold everything worse than the nuts (100% fold since they can't have the A), but also checking the nuts has the same EV as betting since it's all 0EV regardless.

GTO Wizard is significantly higher quality than solver+. The solver+ is fine for the kind of analysis you do on a phone, but GTO+ has more accurate preflop ranges, more robust solutions, and much bigger trees.

Those are discontinued.

From what I've read on their discord, they're making their new preflop ranges free in a few weeks (to combat pirating).

Also recommend checking out the DonkPot discord. They took the free zenith monker solves and made their own viewer.

Something to consider is that blockers dictate equity which dictates hand strength.

July 10, 2021 | 8:35 p.m.

You have to identify where they split too value heavy. You can absolutely burn a ton of money exploiting the wrong direction.

1) We assume villain is balanced and polarized on the turn, but will give up too much on the river. We call turn wider to exploit by over-realizing medium hands.

2) Villain was actually underbluffing turn, so your exploit backfires and you end up with a bunch of garbage with no real SDV against a range that has you crushed.

p.s. the real exploit lies in destroying their castrated checking range.

July 3, 2021 | 4:07 a.m.

Use stronger bluffs on the river. Not every 0-equity hand has to be turned into a bluff.

Identify the bottom of your calling range; you have tons of pairs/heart blocker type hands that are too weak to call and make better raising candidates. There's really no need to reach this far for bluffs.

If you want to understand this from a theoretical perspective, try solving the 0-1 game.

MDF doesn't work here, because "bluffs" have equity, and "value" isn't pure value. Checking back has EV.

Both players have a random hand strength from 0.0000 to 0.9999 or anything in between. OOP checks everything, you can pot or check back and see showdown.

What's your weakest value bet? What's your strongest bluff?

It's villain in the BB?

What was villain's turn action?

June 24, 2021 | 6:02 a.m.

Not sure it matters but the pot size is 1294

Did you solve it beyond 2% accuracy? What's the dEV?

28/1294 = 2%, so this could just be noise if you didn't solve far enough.

You probably confused equity and EV. Post pictures.

When you bet the flop, you reduced their range to mostly Jx, 6x and 2x. When the turn pairs, the aggressor should generally slow down, as the defender will often have a higher proportion of trips.

You then proceeded to overbet shove 3x pot on the turn for some reason. That's a huge mistake.

May 25, 2021 | 6:44 a.m.

The vast majority of BTN's range are pocket pairs and overcards. They have a lot of medium and not that much air, so you aim to make their pairs indifferent, which requires more fire power.

25% of your range (overpairs+) beats like 90% of their range (99-), so you can definitely polarize the flop. If you were deeper than your reverse implied odds from running into trips becomes more of a problem.
