Okay I am definitely communicating with an autistic person, I don't mean this as an insult, but I am less annoyed with you. You clearly only understand answers in a direct literal form, and even though I've tried very hard to reach you, you're still completely confused.

You are the only person in a thread of thousand of people that can't grasp these simple concepts.

Memorizing a string 15 moves is usually a useless practice (can you guess why? I'll tell you), because even if 7 moves go your way, the opponent will probably do something different and your 15 move trick fails.

You don't understand what the thousands of people in this thread mean when they say trick. You haven't grasped that yet, you're behind absolutely everyone here.

There truly are no tricks in chess, there are no moves that will get you in trouble, anything and everything is perfectly acceptable. However, if you are playing somebody that is a far greater player than yourself, whether that's your father or a grand master of the game... you will likely lose, every. single. time.

One thing you can do, however, is memorize a string of moves that he might fall for. The reason this is called a trick (by everyone here), is because it is his only hope. It is very unlikely to succeed, and it risks everything - it puts him at a disadvantage if ANYTHING does not go to plan.

Please use your intelligence to process this sentence: you needn't be good at chess, to remember a string of moves. It does not take skill. It is very unlikely that a great player will fall for your memorized moves, but once in a blue moon you can win.

That's what happened here. And it's clear to absolutely everyone that the trickster is probably a novice, and the grand master would beat him 10,000 times in a row if they kept playing.

I am repeating this because you are incredibly dense, like unfathomably dense.

NO MOVE IS A TRICK, UNLESS YOU CAN'T COMPETE WITHOUT IT WORKING EXACTLY ACCORDING TO A VERY SPECIFIC PLAN.
