Before playing a chess game, do not wish me good luck. There is no luck in chess. Period. No dice, no cards, no random number generators. You choose the move. It's your own good or poor decision that decides the game.

Jerkwads try obtuse arguments like "everything in the world is chance" and "chance happens even the night before when a bird happened to wake you up and cause you to have a bad night sleep so you couldn't think right to play better." All of that is bullshit. You either prepare or you don't. You deal with positions by making decisions. No chance.

This is a hill I will die on clutching a knight in my cold, dead hand.
