I love chess personally and was in my high school chess club for a year. As a chess player, I'm like the slowest guy you will ever play, mainly because I'm overly cautious and go through multiple possibilities rather slowly (weak Ne, I guess. I remember my ENTj friend being like this too.) Funny enough, that trait by itself allowed me to win a number of games, because the faster players would get bored and lose track of what was happening (and they'd get pretty annoyed at me for it too.) Of course, the joke's on me when the game's timed as I get nervous as hell and have an impossible time concentrating when someone throws a clock into the mix (this pretty much goes for anything I do in general, well, for things where I have to think, anyway.) Personally I'm a positional player mainly who likes closed games over open ones, as it slows things down by default, adds a little variety (open games tend to all look the same), and gives me more of a sense of 'struggle', as I don't really like when things go so easy. When I was in the chess club, I was probably the only guy who went home at night and did research on how to play the game better. I pretty much always do this with everything, though, wanting (or rather, needing) to gather enough information about an endeavor beforehand and not just go into something blindly (although there are times when I don't do this and am a bit impulsive. I don't know, it's hard to explain, but whatever, Te valuing anyway.) I was always just a bit afraid of letting people know I did this, not wanting to be called 'stiff' or 'unsure' or 'know-it-all' or...something. Anyway, when I think about moves in chess, I'm kind of limited in my outlook about horizontal possibilities and rather approach them through the lens of time (Ni), and I constantly recheck my decisions again and again...and again and again and again and again and again and (wait, I'm not done yet) again and again and again and again and again (ok, now I'm done.
) That's mainly why I'm so damn slow at chess.
