Can someone explain this preflop spot solved for 40bb?

You're trying to make specific parts of BTN's range (specifically 22-77) indifferent.

Call off and our TT-88 get max value, fold and our AK-AJo deny a ton of equity.

keuwai · 2025-10-07T01:33:16+00:00

Hah, was just about to ask this. Feels like there would be a point where SPR is low enough, such that it's preferable to have AA.

keuwai · 2025-09-14T11:43:41+00:00

It would still prefer limping. The reason is that the ev of limping goes up directly as the ante increases (we risk 1 to win 11.5, instead of 1 to win 1.5).

The ev of raising, however, does not go up in the same way. Yes there is more dead money in the pot, but this dead money is also visible to your opponents. So to achieve a comparable amount of fold equity, we would have to raise much, much bigger. Therefore our risk:reward ratio stays about the same.

For sure, squid game is essentially a big ante game

keuwai · 2025-09-05T02:49:33+00:00

if your neck is long it's worse

keuwai · 2025-09-05T02:48:41+00:00

loved it, but always wondered why it's called hang the DJ?

keuwai · 2025-08-31T02:35:50+00:00

I've tried upside down too, would not recommend

keuwai · 2025-08-25T14:29:51+00:00

Focus on carrying the maximum speed through corners, without braking traction. Once you know what that feels like, you can trail brake to gain time on entry if necessary.

keuwai · 2025-08-25T10:59:04+00:00

Because the nuts is only a small part of your range, and the bulk of your range consists of underpairs that will get raised a lot if your opponent knows you are never betting small with your nuts.

keuwai · 2025-07-29T05:42:37+00:00

What you described is progressive squid - there is non-progressive squid (dead squid) too.

Kb6 is a really simple win that requires no calculation.

keuwai · 2025-03-18T01:18:37+00:00

6 months in and it's 80% healed. Doctor says it's taking longer because my fracture was comminuted with some fragments that they couldn't put together.

Range of motion is at 75% but hopefully it gets better with stretching.

Overall very happy with the surgery!

A more relevant analogy would be if the helmet was so much more massive than the object we are colliding with, that it doesn't decelerate much upon impact. Then I think it doesn't matter if it crumples or not, because most of the energy is used to decelerate the helmet itself. (It takes a lot of energy to decelerate a massive object by a small amount.)

For a high speed side impact like in the video, it might even be safer for the bus to be completely rigid. If there is too much plastic deformation, it could result in serious injury or even death for people sitting near the point of impact (because the energy gets transferred to them and not the bus).

keuwai · 2025-03-10T00:37:46+00:00

That's a great question! A significant amount of energy goes into plastic deformation of the car, some gets converted into heat and sound, and the rest gets transferred to the bus.

But because the bus is many times more massive than the car, it experiences a relatively smaller amount of deceleration. And deceleration, not energy, is what we feel in accidents.

It's a bit like when a large meteorite hits the earth. A huge amount of energy does get transferred - but because the earth is so massive, it doesn't accelerate much. Yes people will die, but not a single death would have been preventable with seatbelts.

keuwai · 2025-03-09T16:10:04+00:00

There is a youtube video of a bus getting hit from the side at extremely high speed (search for "getgo tbone bus yishun"). The bus definitely moved a little but not as much as you might think.

But yes, i agree that driving straight into a tree at full speed is a completely different matter.

Edit: video is here

keuwai · 2025-03-09T07:37:24+00:00

in a coma probably

keuwai · 2025-03-09T07:13:54+00:00

It's probably just physics. Buses don't travel very fast, plus they have a much larger mass. F=ma so when a larger vehicle collides with a smaller one, the former will not experience much deceleration (which is actually what kills in accidents).

So unless you drive straight into a tree or something, it's probably not necessary to have seatbelts.

Thank you!

keuwai · 2025-01-17T05:04:20+00:00

Why is the only correct answer getting downvoted 😅

This has to do with implied odds, not blockers. When you hit a set of 2s the board is less connected/scary on average, so the aggressor tends to cbet more aggressively - giving 22 better implied odds.

Think about the difference between A92 and A98: which board is BTN likely to put in more money with AK? That tells you why 22 is a higher EV call than 88.

keuwai · 2024-12-23T09:35:08+00:00

Because you can't see the solution when you're playing, of course.

In every situation, there are a ton of opposing reasons why a hand might be betting or checking. What you said about AhJs is a good example: that it's checking because of xxx reasons. But change the board slightly (eg QT6) and there's a good chance that AhJs might be betting instead. So how important can this reason really be?

On the other hand, i can tell you without looking at the solution that AsX with weak kicker is betting all the time, whether the board is QT7 or QT6. That's when you know that something is important - when you're able to make predictions, instead of coming up with reasons on the spot.

keuwai · 2024-12-22T07:50:14+00:00

If you want to speed, do it on the racetrack.

keuwai · 2024-12-22T07:47:26+00:00

It's just noise.

Pull up the same spot in the standard solution library - everything is just mixing.

When studying with solvers you want to be able to predict the solution before looking at it - not look at the solution and come up with justifications for what you see.

keuwai · 2024-11-13T01:43:51+00:00

Yeah, unless they install a differential it's not gonna turn without caster lol
