I'd speculate about the natural talent player....not in combination with the other categories. Without study and experience, I would guess such a player might take longer to move since he is reinventing solutions. He might also be more susceptible to classic traps.
However, I don't think this would enable you to diffentiate very accurately.
I guess you can say, there's no way to tell.
So, though I'm not very good at chess, I'm aware of three kinds of players.
1. Natural talent players.
2. Long-time practice players.
3. Study players.
(4. Combination of all 3, but 4s are usually too high ranking for me
.)
I realize that this is usually irrelevant to the actual game. Nonetheless, I (for some reason) find it interesting to know. Because I'm too shy to ask the player, and because I'd like to be able to tell without doing so, is there any way to spot which category my opponent falls under? As in, general playing styles for each category?
