@DeepBelowTheSea @xxl23 On the turn in multi-way spots where the flop has checked through, the player in the middle can often steal it because the other players won’t have balanced ranges in this line. People like to bet without patience.

@aceragoff @pokerorg So you are telling me just because I now can have any combo at equal weight, I’ve somehow lost range advantage as the preflop aggressor?

@pokerorg The Annette15 Challenge doesn’t work as well when your opponents know you are playing blind.

This week I moved from Florida to Minnesota and left the poker industry. I’ll still be working in the gambling world but it’s tough to leave something that has given me so many amazing friends, memories, and opportunities. I’m excited for what’s next and terrified for winter

Glad you enjoyed reading it. Since you clearly have read it, something I have always wanted to ask you, as you have totally read it. If capital allocation is the true function of extreme wealth, and economics is fundamentally an allocation problem, then the billionaire class isn't consuming resources — they're performing a quasi-governmental function of directing civilisational priorities. That being the case, on what philosophical or democratic basis do we justify that this function — the single most consequential act in any economy — is assigned not by consent, election, expertise, or merit, but purely by the accident of prior capital accumulation? And if your answer is "market efficiency," you must also explain why the market, which correctly prices a sandwich or a haircut through distributed signals, is equally reliable at pricing a 30-year infrastructure bet, a speculative technology, or a geopolitical gamble — decisions where the feedback loop is so slow, so distorted by the allocator's own power, and so irreversible that the error-correcting mechanism markets depend on simply cannot function. You're not defending the price mechanism. You're defending something closer to hereditary planning authority. So what, exactly, is your actual argument?

Wow. Really well written and reeks of truth…
Brivael Le Pogam@brivael

Elon Musk avait dit un truc qui m'avait marqué sur l'allocation de ressources. En substance : passé un certain niveau de richesse, l'argent n'est plus de la consommation, c'est de l'allocation de capital. Cette phrase change tout. L'économie, dans le fond, c'est juste un problème d'allocation. Tu as des ressources finies et des usages infinis. Qui décide où va quoi ? Imagine une cour de récré. 100 enfants, des paquets de cartes Pokémon distribués au hasard. Tu laisses faire. Très vite, un ordre émerge. Les bons joueurs accumulent les cartes rares, les collectionneurs trient, les négociateurs trouvent des deals. Personne n'a planifié. Et pourtant chaque carte finit dans les mains de celui qui en tire le plus de valeur. Le système maximise le bonheur total de la cour. C'est ça, la main invisible. Maintenant fais entrer la maîtresse. Elle trouve ça injuste. Léo a 50 cartes, Tom en a 3. Elle confisque, redistribue, impose l'égalité. Trois effets immédiats. Les bons joueurs arrêtent de jouer, à quoi bon. Les mauvais n'ont plus de raison de progresser, ils auront leur part. Les échanges s'effondrent. La cour est égale, et morte. Elle a maximisé l'égalité, elle a détruit le bonheur. Le problème de la maîtresse, c'est qu'elle ne peut pas avoir l'information que la cour avait collectivement. C'est le problème du calcul économique de Mises, formulé en 1920. L'URSS a essayé de le résoudre pendant 70 ans avec le Gosplan. Résultat : pénuries, queues, effondrement. Pas parce que les Soviétiques étaient bêtes, parce que le problème est mathématiquement insoluble en mode centralisé. Quand Musk a 200 milliards, il ne les consomme pas, il les alloue. SpaceX, Starlink, Neuralink, xAI. Chaque dollar est un pari sur le futur. Et lui a un track record. PayPal, Tesla, SpaceX. Il a démontré qu'il sait identifier des problèmes immenses et y allouer des ressources avec un rendement spectaculaire. L'État aussi a un track record. Hôpitaux qui s'effondrent, éducation qui décline, dette qui explose, services publics qui se dégradent malgré des budgets en hausse constante. Le marché identifie les bons allocateurs, la politique identifie les bons communicants. Le profit n'est pas une finalité, c'est un signal. Il dit : tu as alloué des ressources rares vers un usage que les gens valorisent suffisamment pour payer. Plus le profit est gros, plus la création de valeur est grande. Quand Starlink est rentable, ça veut dire que des millions de gens dans des zones rurales ont enfin internet. Quand un ministère est en déficit, ça veut dire qu'il consomme plus qu'il ne produit. L'un crée, l'autre détruit, et on appelle ça redistribution. Dans nos sociétés il y a deux catégories d'acteurs. Les entrepreneurs et les bureaucrates. L'entrepreneur prend un risque personnel pour identifier un problème, mobiliser des ressources, créer une solution. S'il se trompe il perd. S'il a raison, ses clients gagnent, ses employés gagnent, ses fournisseurs gagnent, l'État collecte des impôts. Il est la cellule de base du progrès humain. Le bureaucrate ne prend aucun risque personnel. Son salaire est garanti. Au mieux il maintient une rente existante. Au pire il la détruit par excès de réglementation, mauvaise allocation forcée, incitations perverses qui découragent ceux qui produisent. Mais dans aucun cas il ne crée. Regarde les 50 dernières années. iPhone, internet civil, SpaceX, Tesla, Google, Amazon, Stripe, mRNA, ChatGPT. Toutes des inventions privées, portées par des entrepreneurs, financées par du capital risque. Pas un seul ministère n'a inventé quoi que ce soit qui ait changé ta vie au quotidien. La France est devenue le laboratoire mondial de la dérive bureaucratique. 57% du PIB en dépenses publiques, record absolu. Une administration tentaculaire, une fiscalité qui pénalise la création de richesse. Résultat : décrochage face aux États-Unis, à l'Allemagne, à la Suisse. Fuite des cerveaux. Désindustrialisation. Dette qui explose. Et le pire c'est que la mauvaise allocation s'auto-renforce. Plus l'État prélève, moins les entrepreneurs créent. Moins ils créent, moins il y a de base fiscale. Plus l'État s'endette et taxe. Boucle de rétroaction négative parfaite. La maîtresse pense qu'elle aide, et chaque année la cour produit moins. Dans nos sociétés, ce sont les entrepreneurs, toujours, qui font avancer la civilisation. Les bureaucrates au mieux maintiennent une rente, au pire la détruisent. Aucune société n'a jamais progressé en taxant ses créateurs pour subventionner ses gestionnaires. La question n'est jamais qui a combien. C'est qui alloue le mieux la prochaine unité de ressource pour maximiser le futur de l'humanité. La réponse depuis 200 ans n'a jamais changé. Ce ne sont pas les fonctionnaires.

@PokerJermz @GTOWizard Most streets I’ll play a max of two sizes so nothing crazy because I do value a simplified strategy. I’m also never checking this board because I know villains won’t play vs any bet well enough. They aren’t finding enough 43o xr’s so here I’d just range bet small.

@surreal_ex @GTOWizard Looking at the multi size solution It checks 25% of the time, so half as much as single size Seems like multi size solutions are more up your alley.

Been messing around with single size sims in @GTOwizard KJ3 rainbow: used to bet 4 sizes at different frequencies Now it’s basically: 115% pot ~50% frequency Feels way easier to execute… but most players still won’t pull the trigger on an overbet c-bet strategy Will you?

@PokerJermz @GTOWizard Agreed. For sure the large bet will get people out of their comfort zone and they will not know the best way to respond. Downside we have checks. That competes with the fact that population chronically under xr’s small cbets even in spots they know. Which helps our whole range.

@surreal_ex @GTOWizard yea good question...guess it really depends on the opponent. But in general, I would guess people would make less mistakes, but the mistakes they do make would be bigger

@PokerJermz @GTOWizard For sure don’t disagree. I guess my argument is taking the form of, we make money when villains make mistakes. Are they really making more mistakes vs overpot compared to a small bet? And how impactful are the types of mistakes to our winrate.

The thing economists don't understand is that -EV wagers are rational when the "risk-free alternative" sucks.

@PokerFlares @Sdavies22 If villains don’t bluff enough, which is true across most levels of poker, mdf will kill your ev. And that’s not even getting into big blind flop defense which already overfolds compared to mdf.

The most important skill in poker, at nearly every level, is losing less money to your opponents value bets.

@tombos21 Beyond just getting paid, is it also fair to say that because in icm chips won are worth less than chips lost, we are paying a higher fee to chase a less valuable draw?

Tournament poker devalues small pocket pairs and suited connectors. Part of this comes down to stacks being shorter, but it's also an effect of ICM. Drawing hands and small pocket pairs rely on implied odds to breakeven. They lose a small pot often and make up for it by winning a huge pot sometimes. But in ICM-heavy spots it's much harder to get paid off when you hit your draw. Below I compare two identical sims: chip EV and ICM. You can see the ICM solution shifting away from suited connectors and towards blocker-bluffs.

@tombos21 My study group talks about this a lot and it’s a great point. It’s also why I stress looking at percent of field left to bust instead of players left to bust to make the money. 1 away with 18 paid and 150 paid are vastly different. Increased by mistakes as mentioned!

A big chunk of your MTT ROI comes from volatile players on other tables imploding vs each other. Solvers can’t see that. They treat every external stack as static (paying out their ICM value), so they systematically undervalue fold EV. That’s why I think Ben’s success with over-folding isn’t just about dodging the nit tax. It’s also about collecting the EV leakage from other tables. x.com/bencb789/statu…

@surreal_ex @tombos21 @hungryhorsepokr Why would you ever donk if you know villain is always range betting? Makes no sense to me. You usually donk OOP when you don't want IP to xb medium SDV hands. Since villain is range betting IP, donking losses it's merit. The exploit is to check raise agressively.

There's a reason @hungryhorsepokr advocates for checking to recreational players on the flop. It's well known that fish turn their hands face up when you check to them on dynamic textures. Example: BvB on QJ9r. If BB has a “bet any pair” tendency, SB can exploit by checking range and letting BB self-identify strength. Sure, “bet any pair” is an extreme nodelock. But it doesn’t take much information asymmetry before the optimal play funnels every hand into this line. Moral of the story: Sometimes you need to take your foot off the gas and let your opponent tell you what they have.
