GTO trees are far too complex to fully memorize, so nobody can play perfect GTO. But you can do a lot of solver work to get reasonably close.
The tell was a very common one. Anytime he liked what he saw, either hole cards or on the flop, he would quickly glance at his chip stack (thinking about a bet). Probably didn't even realize he was doing it. When it got to head to head, if he glanced at his chips...I'd fold early. If he didn't, I'd bet into him until he eventually folded.
- limp-shoving under the gun
- always trying to go on runs
- over playing suited connectors (JTs specifically)
But, you still get the advantage of being able to recognize it. There's lots of good wisdom in there that isn't as prescriptive either. Read as many books as you can. Poker is information warfare.
There are nuggets of wisdom in every poker book I've read even if I disagree with some parts or some are just flat out wrong. Super System, in particular, provided insights into the mind of one of the greatest player of all time. I particularly liked the psychological view on things. If nothing else, it provides context for the ones that came before you. Its been 15+ years since I read it, but beyond the fundamentals, I recall picking up (hopefully not misattributing anything here)...
- a quick, in-your-head method of calculating odds based on outs
- psychology of playing runs and others perceptions of you at the table
- the pitfalls of playing AA
- a realistic look at "tells"
- the general psychology of aggression
- how/where tight players make money and how/where aggressive players make money
Super System is the seminal book of poker. It is the book that your opponents are most likely to have read. As I alluded in my original comment, you wouldn't want to be the only person at the table who doesn't recognize someone playing the super system to the letter. IIRC, the goal was to make the player just appear lucky. It was meant to be confusing. It's like reading K&R as a C programmer. Sure, some of the information might not hold up today, but it provides a lot of context.
But I do really appreciate hearing your perspective on it.
Sorry, why are you answering a question if your first response is “no idea”? Am I missing something? If you have little information, my feeling is that your response is at best just BS? I know that sounds very rude, I’m sorry for that.
Are today's online tables simply impossible to win? (bots, collusion)
Or are players simply too evenly matched and the house rake/fees kills you anyway?
So basically "You've got to know when to hold 'em, know when to fold 'em, Know when to walk away, know when to run." :)
