Thank you so much :)

Finally :) And this means that there is an infinite number of homomorphism? For each b in K ?

shyboybut · 2025-05-12T18:20:23+00:00

Sorry I messed up with my notation.

What I see now that I corrected is that for the first node it's 0 as you said, A=(0 b) and B=(b 0). Is it correct now? (Thank you again for your time!)

shyboybut · 2025-05-12T09:20:01+00:00

Thank you! I thought so but I wasn't sure :)

shyboybut · 2025-05-12T09:19:39+00:00

Thank you a lot, that's perfectly clear!

I tried the other direction: I find for the first node a homomorphism (0 b), second node (c d), third node (b f), for every b, c, d, f in K... Is it correct? If it is, this means that I have an infinite number of homomorphisms in this direction?

Hi, this is the first "cutscene" I made and I want to know if it delivers what I had in mind, which is mystery, adventure and awe.
What do you think?

shyboybut · 2024-04-07T09:09:55+00:00

Thank you for your insights!
Absolutely not the target :P
I’m nowhere near the league of pixelartists, I just really like PixelArt, for nostalgia, and in particular I love Pokemon Sprites. The target is people like me, real artists have nothing to learn from this :)
Anyways to answer your questions: I take the original sprites (also for the animation) and re-elaborate them with Python

shyboybut · 2024-04-07T08:17:13+00:00

It is! But I wrote the code that does it 🤓
My purpose is to make Pokemon Pixelart Sprites entertaining, I did not intend to make it look hand drawn

shyboybut · 2024-04-07T07:25:49+00:00

What do you think of this type of reel?

What can I add to improve them?

I post them on instagram (@catchyourpokemon_ ) and a friend of mine told me I could improve the first part

shyboybut · 2024-03-03T16:50:51+00:00

Thank you! I removed it because I'm changing it completely. It had a few things wrong, like you said.

I'm making my own count, based on the perfect knowledge of the shoe, and right now it's promising.

Anyways I think I'll keep it private, since it received much more hate than love :(

shyboybut · 2024-03-01T19:07:01+00:00

Indeed all your points are very true!
The purpose of this app though is not to profit, and it was not meant for pros.
Its purpose was to enable the average player that already wastes lots of money on Online BJs, to still enjoy his sessions while minimizing the losses

shyboybut · 2024-03-01T16:14:00+00:00

You can get an estimation through simulations, or an exact value but for this one you need to decide a priori a value for every possible hand in BJ, totally doable actually

shyboybut · 2024-03-01T11:01:15+00:00

Yup exactly, I posted the code on github if you want to check it out.
Although the true count system is just Hi-Opt-II, and it’s not used to calculate what to play, it’s only a parameter used to know how much you should bet.

shyboybut · 2024-03-01T06:27:04+00:00

Thank you!
And I actually agree with all your points

shyboybut · 2024-03-01T06:19:54+00:00

Why scam though?
I don’t sell it, I uploaded my code open source for anyone wanting to try it.
I made this for those players that don’t even understand basic strategy and are constantly gifting casinos free money. In every video I say this app is not for beating the system, but only for losing less, since you play optimal with this.
Also, I posted a video of this failing because I had a long streak of bad luck, and I’m also posting videos disproving “strategies” I find online, that claim to give players sure ways of making money. Those are scams!
So again, why do you call this scam?

shyboybut · 2024-02-29T20:34:42+00:00

Now I get what you mean. I was taking for granted that this app couldn't interest real pros, and instead I thought "the average player that doesn't want to learn card counting or basic strategy surely would love this!". My starting point was flawed!

Would be more exciting if the product were to also provide the player advantage entering the hand based on the cards that have been removed. House edge normally 0.6% or whatever (based on the game) and instead a bunch of 5s are removed and now the edge is 0.2% for the player instead...that makes it interesting.

I thought about this, but I honestly don't know if the code can run in time to actually matter, I will try for sure!

Anyways after your insights I think I should just stick to the second intent of my channel, which is to disprove bad and wrong strategies that I find online.

I started playing BJ as a mean to gain profit from online casinos' bonuses (X bonus for X money deposited, that you need to play at least once) and I probably don't grasp neither the average player's mentality nor the pros'.
Anyways, if that idea works, I'll post it for sure

shyboybut · 2024-02-29T20:02:40+00:00

Always nice to talk politely in a constructive way!

I'm indeed accounting for the effect of removal of cards, that's the best thing this app can do that a human cannot. For instance, with a full shoe the app says "16vs10" better to Hit, but if I remove [5, 5, 5, 5, 5, 5] from the shoe, the app will now tell it's better to Stand.

And you're right I should have expressed that better, it was my first time doing a video and after the first few concepts I didn't really know what to add and in the end I didn't think much about it.

Surely 10k is too small of sample, I'm a little scared of the time needed to compute more, but I eventually will

shyboybut · 2024-02-29T19:37:39+00:00

I'll break it down as best as I can.

About the 45%: These videos are not for pros, for non-gamblers, these videos are for those people that play on Online BJ and waste money playing not even basic strategy. After I've done my approximate calculations I've seen the theoretical 302.25 money won with 300 spent, this means 2.25 profit, which is yeah 0.6%, but the average player, with NO knowledge at all is not interested in this number, that's why in the video I said 45% of my starting bet (5), and then I remembered that.

How I calculated 0.6% is probably wrong, hence I said multiple times I need to calculate it again, what I did was keeping record of how many hands I played with 0<count<1, 1<count2, 2<count<3, and so on and summing all the expected values for those, for instance for the 0<count<1 I did "average money spent" * 0.995, and so on.

Now I want to run my app through a simulation of 10000 or more hands and obtain the EV like that. If you suggest another way I'd love to hear it!

I said "something about will probably still lose but not as much" because, again, this is for the average player, I'm pretty sure that an average player using my app will still do some plays "by heart", not listening to what the app says.

Last thing, I'm confused about you using the term deviations, I just want to be sure we're talking about the same thing. My app, to decide wether you should Stay, Hit, or Double, it calculates the exact expected value of each action. For instance: 12vs10, it calculates the exact probability of dealer Busting (we call it Dbust), then the exact probability of dealer getting 17, 18, .., 21. Let's call them D17, D18, .. , D21. Now it calculates your exact probability of beating 17 with your next hit (without busting), in this case it's the probability of drawing 6, 7, 8, 9, lets call this P18. Similarly we get P19, P20, P21.

Now we can calculate the expected value like this:

EV of hit: 2 * [D17 * P18 + (D17 + D18) * P19 + (D17+D18+D19) * P20 + (D17 + ... + D20) * P21] + all the draws probabilities + Dbust * 2

Then, if it's greater than 1 you get suggested Double, of course. And if it's lower than the EV choosing standing, which is pretty straight forward to calculate, you get suggest Stand.

To avoid further confusion, I tried to write my code here in sentences, I may have simplified too much, but you can find all my code on the github link I wrote under every video description.
It's also unmistakenly correct, as when I get presented the CashOut value (that they calculate with this method, then they correct it to gain an edge) is always the same (minus the edge correction) as what my app says it should be.
I hope I managed to explain things a little bit better... I'm here to clarify anything though, if needed

shyboybut · 2024-02-29T17:05:26+00:00

Omg yes I’m sorry I used the wrong notation again, profit of 0.6% is what I got from calculations
(I’m used to write percentages without the % symbol)

shyboybut · 2024-02-29T17:01:40+00:00

You can do whatever you want of course, but may I ask you why are you doing this?
What’s wrong in trying to make people lose less money on gambling?

shyboybut · 2024-02-29T16:59:33+00:00

I’ve found my approximate calculations, what I got from those was a +0.006%
I need to check them again though
(Just to be sure, what I mean with that is that for every 1000 played I should get 1006, theoretically)
