1300 player has no positional understanding.
Question would be more interesting if it was a 2000 player vs a GM, i.e.: somebody that is good at chess vs a professional GM.
Oh yeah, much better question. Because to a GM experts definitely don't play shit chess.
Fun fact. GMs think less of experts than you do 1300s.
That's just a guess, right? I don't think that's likely to be true. I think they can respect the fact that 2000s know enough not to make the most obvious of mistakes, and understand, also, that it takes a lot to climb to 2000, and a lot of thoughtfulness about the game, since after all, the GMs once had to get to 2000 themselves.
I mean, you can always use the relativism argument, but I'll apply that to my own perspective: I used to think it was great to be 1500, sure, but it's not like I think that a 1500 is a patzer now either -- I'm 400 points higher than that, but I respect the fact that 1500s are not often hanging their queens, and are actually trying to do something useful in their position. Tieing in to my earlier point, I once had to climb to 1500, so I know how much your play gets refined in doing so.
there's like an infinite 0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001.
