Earlier quoted context omitted.

> Startup game is more like poker . It is very different from chess . That’s the point of the article. It contrasts the thinking styles of ‘founder-types’ and ‘scientist-types’. As a (in the terms of the article) ‘scientist-type’ who regularly gets lost in the weeds of the details, I found it a pretty interesting commentary.

This is not quite true, because poker is fundamentally adversarial, while startups are mostly not adversarial, at least not directly. Startups are a beauty contest where each player focuses on maximizing the things about them that appeal most to a panel of judges (customers). Similar to the scramble competition that Benenson cites here, rather than an arm-wrestling contest. https://pubmed.ncbi.nlm.nih.gov/31400660/

Startups are competition. You're fighting with others to put up the best product in market. It's a race against time as well.

So: good (chess) players spend more time mentally countering their proposed moves before moving. For developers or managers on HN, one outcome would be that it's best to start one's career in testing, or to respect the resumes of those who started in QA. If/since there are hundreds of ways things can break, it's a harder problem to show how it will, or prove it won't; and building a mental library of fault models hel…

I think the ideal first job in tech is IT help desk, not QA.

Everything that shows up to the help desk is broken. QA people need to have a skill for breaking things or at least an awareness of how things break. They will learn this at the help desk.

Otherwise: I completely agree.

Interesting observations, I would add my own: - during long game, chess grand masters have physiology comparable to marathon runner, while he runs. Deep thinking for several hours, takes huge load on body. All the logic and critical thinking, is not going to save you, if you are not fit, and your brain does not work correctly. - real life is not about solving puzzles. Real life is a rigged game where rules are not en…

> real life is not about solving puzzles He says, before laying out the outline of the puzzle and giving suggestions on how to go about solving it Everything can be about solving puzzles if you let it. Given enough time and patience you can understand anything - the only interesting question is, how to you decide what to focus on? Navigating life is absolutely an exercise in puzzle solving, at every step you know whe…

From rule 2):

> It’s hard in real life, too: vanishingly few people are meta-rational enough to try really hard to falsify their own ideas. Your brain really wants to find reasons to support what you believe.

I don't think he goes with "meta" deep enough. It is great for engineering problem solving mindset But it is also a good way to end up like underpaid post doc, who needs second job just to pay rent.

And this type of advices are usually coming from someone who "made it", has its own house and is practically retired. Very impractical and harmful (to some extend) for young minds.

Practical implementation for young person is not "falsifying" and trying again again. But coming with solutions that takes minimal time, is good enough and comparable to coworkers who work on the same salary. Time you save can be invested into education, family, hustle and so on.

I disdain this pessimism that is all over the internet.

What pessimism? I am talking about health, opportunities...

Starting family today is very difficult, there is no easy and direct route.

> - real life is not about solving puzzles. Real life is a rigged game where rules are not enforced. Instead of finding problems to solve, you need to find oportunities (and loopholes) and exploit them!

"Real life puzzles" are too open-ended and have too many levels to really be called puzzles. A puzzle has a closed set of rules that usually gives you only one level on which to solve the problem. Many interview questions could be described as puzzles. A "real life" programming task has a bunch of different levels: what's the real problem the customer wants solved, is this the problem this customer wants solved first, do we have a bigger customer with a bigger problem you should be working on instead, can the problem be solved without programming, should the problem be solved in a different system, are there other people on the team who solve problems like this in their sleep and they'll give you the answer in five minutes if you describe it on Slack? If it does seem like you need to solve the problem, what's your level of confidence that with investment of X time you can solve the problem, for different values of X, and given this information, does it still make sense to try to solve it?

What makes puzzles relaxing and reassuring is knowing that there is a solution, and that you know all the rules. Also, you know that you'll recognize the solution when you get it. Real life rarely gives you that reassurance. With a real-life problem, you don't know if there's a solution, and even when you have one, you can't know that there wasn't another solution that would have been much better, because of possibilities you failed to consider. The only way to turn a real-life problem into a "puzzle" is to strip away the open-ended real-world context and present a subset of it that can be described in a closed form.

I think you're missing the point, while you are pretty correct IMO, viewing the world in such a dichotomic way misses the fine details along the spectrum

Spot on. When you discover that people are solving a problem by considering a wider context than you did, do you broaden your thinking about the problem, or do you accuse them of cheating and complain that the rules aren't being enforced? Morality and (most) laws should be respected, but outside of that, rules shouldn't stand in the way of solving problems.

I wouldn't be so hasty to say it is obvious (parent made no claims about calories).

Many top chess players have considered themselves athletes, and if you've ever tried to calculate under pressure at a board for a few hours, I'm sure you'll agree it is an exhausting activity. Fischer engaged in athletic training when preparing for tournaments, for example, to aid in maintaining mental focus (he wasn't unique).

It would be silly to say that 2400 Elo indicates you can run a four-minute mile, or that calculating 6-ply in a closed position burns the same calories as running a block. If the claim is 2400 Elo tend to have similar vascular flow in the brain to people who engage in aerobic exercise or something of that nature -- maybe?

> "What stops you, I think, is a combination of not really believing you’ll get it and not really caring. Is that too harsh – or is it somewhere close to the truth?" This reminds me of the curse of working with really good senior engineers. They already know the answers, they've already solved the puzzles. It can be very easy to just defer to them all the time. If you are a senior engineer who really understands a sy…

In my experience, people underestimate their abilities and are so afraid to mess things up, even in a preprod environment, that they don't even try. I try to encourage people and let them know they can't mess anything up, but like the saying goes, you can lead a horse to water, but you can't make them drink. Some people get it faster than others.

There's also the pressure from above to fix things quickly, meaning some people don't have time to really explore and learn and need to be given answers...

Hah, what a great article.

I play chess (poorly for the time spent on it) and I'm also a reasonably successful founder of a couple software companies. I find my struggle with chess is that I want to act intuitively, something that has served me well all my life in other avenues. But the board doesn't lie and if you don't think thoroughly you will get punished.

I have the capacity for it, I can think thoroughly in puzzles and perform much better there than my on board play but I just struggle so much with the discipline during regular games to falsify my moves. So much so that I've mostly given up on trying to improve despite really loving the game, it just grates on me. I know I could be better but I lack the discipline and I guess I just don't want to exercise that discipline in a game.

Anyways, great article.
