Do you play by intuition?


Yes, I would put myself in a similar rating bracket having played chess for years. I can calculate accurately only so far and many times I have a position where I am unsure what is the best move. Then I play what I feel should be best based on intuition - a feeling based on memories of similar positions and my knowledge of general principles and ideas. Sometimes I'm right, sometimes I'm wrong.

Without knowing it, you use a lot of intuition yourself (everyone does). For example in the first move of the game, you have 20 options. For the next few moves you have even more. How many out of over 100 options do you consider? Probably you consider about 1 or 2 options per move. You probably base it on the opening principals, and checks, captures, and threats.
One common thing higher rated players do is categorize the position by pawn structure (there are only a dozen or so basic pawn structures in all of chess, nearly all middlegames fit into one). This tells the player automatically things like what side of the board to seek play on and where (at lease some) of the non-pawns should go. Also piece activity is a major focus, so players are constantly aware of which of their pieces are least active (and they want to move them given a chance) and which of their opponent's pieces are most active (and they want to trade or undermine them given a chance).
Stuff like that.
Pattern recognition may be a better word, but yeah, minimal conscious thought. That's how blitz and bullet games are possible. That's also how a GM can play a 50 person simultaneous exhibition and win every game only spending seconds at each board.
Sometimes this has been referred to as the hand making the move (instead of the mind).

Everything I've ever learned has only improved my intuition. You just sort of assimilate it into your mass of knowledge. Things you learn about endgames (or openings, or tactics, etc) can aid all sorts of seemingly unrelated things.

everyone plays by intuition, you think that all players calculate every possible move on the board? not even the machines can do that, you saw a move that you like and you play it, thats how it works, after playing a lot and seen a lot of games you see better moves and calculate better but everything is about that

Sure, there must be.
But a more important factor, I think, is how much a person enjoys doing the right kind of work. Sort of by accident you know? Like many people enjoy playing blitz or bullet chess. And GMs do too, this is fine, but how many of us enjoy spending 8 hours intensively analyzing a single game? And then 8 hours again tomorrow? And the next day? Or playing over all the world chess championship matches? Or reading a chess book over and over and over?
Some people force themselves to do this work, other people happen to look forward to doing the right kinds of work, it's just part of their personality. That's the sort of genetic difference I think matters most. The people who really enjoy playing and learning about chess.

For example, what would a person ask who doesn't love learning about chess?
They'd ask for the 1 opening they should study (that way they can ignore all other openings). They'd ask which is more important, tactics or endgames (that way they can ignore one or the other). They'd ask if a strategic style is best (that way they can ignore learning how to attack).
In other words, the types of questions you hear all the time from weak amateurs

I think your friend should be able to explain his decision to you since chess is a logical game. Maybe he just doesn't want to take the time to go into the details.
Heck, even in blackjack gambling game, a decent player can tell you why he made his actions. It isn't intuition. Now, betting on the craps table; that's intuition.
Always by intuition...I have hardly any knowledge of openings and end games...
Having no opening knowledge or endgame knowledge does not mean you play by intuition. You could still calculate a lot and that is not intuition, quite the opposite.

Oh, absolutely! I just throw all logic out the window and rely solely on my mystical powers of intuition. Who needs facts and reason when you can make all your decisions based on a hunch, right? It's the perfect recipe for success... or maybe not. But hey, who needs a plan when you can just wing it? Intuition all the way!

Intuition in chess? Oh, I'm like the Albert Einstein of chess intuition! I don't need to waste time calculating moves or analyzing positions. I just channel my inner psychic octopus and let my intuition guide me. I mean, who needs years of studying openings, endgames, and tactics when you can rely on a mystical connection to the chess gods? It's a foolproof strategy. Well, at least until my opponent makes an actual move. Then I'm toast. But hey, intuition is everything, right?
