To me chess and poker are the same game with only the visual difference that needs extra talent at chess.
One needs knowledge from the opening to the end, every part of the game, every street. A weakness on these areas will give worse results. One can see when one performs poorer because of knowledge reasons, though it is not exactly sure one is aware of how much one doesnt know.
The second part is grinding, where every decision made is one move. The aim is to play a game without serious mistakes, preferably against just a level stronger or even competition.
I work mostly on my grinding, neither my poker nor my chess knowledge is lacking too much. The only reason i still sometimes play chess is a part of my aims to improve my grinding, thats maybe 90% of my focus. I dont train tactics, i am good enough there already as knowledge, but i enjoy and train grinding, solid play, move by move, being mainly about positional play i suppose though not that i have a name for it, it being like someones tactics grinding but i just play positional, move by move and it is the only thing i like and is of worth for me. The place one at this time might do this for free is chess.com where there is a solid engine one can play with a tablet. I dont enjoy playing humans as much, as i get so much more and solid and stronger competition and get a game any instantly. Lately, i have played the level 8, thats maybe 100 150 point stronger than my average level, where i hold my own w white most of the time but w black i make a mistake or get outplayed half the time, it being seriously stronger w white, and my black defense isnt as strong as it could be as knowledge but its good enough and i enjoy using my understanding also, not just known ways.
I play c level blitz, slower blitz, faster or slower as the engine game has no time. If i dont blunder, i play as strong as that engine, b level. Thats the strongest i can be at chess, and two things needed to be even that strong is to some improve my black knowledge, but mostly its about becoming a stronger grinder, thats my main aim at poker, using chess sometimes for that practise.
To some, technique, that is, knowledge, is the main thing, but for me thats the smaller part of the game as my basic strategy and balanced play and logic moves are already there, that i can improve only a bit anymore. The limitations of my strength are in talent, eg. i am not strong enough visually to do well at chess calculations against strong players, but other than that its not that i play major weaker, just that i get outplayed at the area of visual calculations and there is nothing i can do about it but play solid and try to hold it positionally.
So, to cap it, i dont give as much value to knowledge, though my technique is good at least at poker, but its as far as it goes and its not some major thing after that, as much work as it took to get good, but the day to day play is 90% about ones grinding ability, the aim being to play mistake free, as that is what really matters.
Two things close the grinding are logic moves, that form the best moves in situations, and the best reads. The stronger poker players are strong especially here. The other is understanding the boards in situations and it connects to technique too, and is much about knowledge but the stronger players understand those boards still better as they can be logic read also and it needs brain power. These are the most advanced things in poker and need attention during the grinding as much of the strenght comes from them when it comes to making money in tougher games, though grinding w basic strategy is what i value the most, there being little i can do to perform stronger than my brain and current knowledge experience, but i can focus on playing w less mistakes, it all adding up.
I think it all as grinding, and just note when i make a smaller or bigger mistake on this area, improving my knowledge. But the engine that puts it all together is ones grinding strength, that they might call ones a.game when it is performing strong. And after the knowledge, that is what matters the most, though if spotting a weakness in knowledge, understanding of the position, like w black, one can improve there.
But what i go and do when i play poker, chess, i go to grind and the focus is in getting through without mistakes, but just like one makes a significant mistake at chess vs. stronger and equal opponent up to every other game w black, one also makes those in a poker game like as often, and maybe less so vs. weaker player as one might get away with it more often.
Just that the stuff one thinks in a poker game is maybe different, it is not different really at all. And though i have a complete technique and can learn when i make a logic mistake, as play or read, its still mostly about move by move grinding, and that is what playing is mainly about.
Maybe a complete knowledge w c.play is like average, w a.play its like a.level. Playing stronger than that isnt possible for mortals, only to talents, high intelligence, freaks of nature. The good thing about poker is that most havent grinded their way up. The freaks are out there and though they seem to be many eg. on chess servers, they are just rare people on this planet and they are there way more often, so it is very rare. In a game of poker one can generally do better w the knowledge, experience, grinding, the experience being the edge one can have against hobby players, and it shows in a game of chess also, though makes little difference vs. weaker players or when playing vs. too strong opponents.
