Nope. A stereotype contains always a form of evaluation (is good at x, is a bad x, can't do x) and is therefore a prejudice. It is a commonly know, maybe even commonly accepted prejudice.
ChaosEngine plays chess. That is a prejudice. I judged that since you seem to be smart and smart people know how to play it, you must be able to play chess. You play chess.
See, I judged you and made a claim based on that judgement. The same way I could argue that because you are black (Shut up, you're black now! So say we all!) you must smell terribly like sausage because it is my experience that black people smell that way(Don't you complain about being black, I have to carry the burden of racism here). Both are not stereotypes (at least not as far as I know) but the facts that you, brother ChaosEngine, are great at basketball and posess a giant penis, are stereotypes.
I can't prove any of those right know, they are premature judgements. You may not know how to play chess and maybe you don't smell like sausages but at least both claims are not commonly made about black people. Because they're not stereotypes.
You still rule at dunking. And let's not discuss the other thing we all secretly suspect about you.

Spellbinding.
Takes the strategic ability to see many moves ahead like chess, combined with the physical skill to execute it under pressure.

I just need to stop feeding the beast. My bad.
How about a nice game of chess?

I like chess..... (*Whimpers)

Yeah, the falcon is a must have. That is awesome. Though I'd purchase this for the chess-set. What an awesome conversation piece.

or basically how to beat someone who's never played chess before

And who doesn't take middle column in connect 4? That's like not taking middle middle in tictactoe

I think Chess would count as how to win ONCE against an opponent not aware of, or not expecting you to try, the fool's checkmate.
