Will McDonald's help you play chess?

                                  This is a game I played when I ate Mcdonald's before the game.

                                        I was playing black against a 2100 and I just smashed him.

Hmmmm quite a good assumption

Try this again

You were black?

It's amazing that you eating at McDonalds would cause a 2100 to play like a 500... ;-)

You ate mac's or at mac's?

The entire question of performance-enhancing foods should be examined more closely.

Do your Knights jump better after a good meal of Cuisses de grenouille?

And what about fish? Fish is brain food. Does it improve your calculation ability?

Could be your breath; that MickeyD's smell can be distracting in close quarters.  

I’m pretty sure noshing on a fillet-o-fish doesn’t qualify as brain food.😉

I think McDonalds makes you play better. Probably buffs your ELO 500 points.

I will admit that McDonald's *will* help you play chess by providing you and your opponent a table to sit at and set up a board...

Only when you play against the McDonnell attack. Or here, my Hamburger variation in the English:

Then you just eat the occasional French fry off of the floor and pull a cup out of the trash for drinks.

MacD’s will definitely help you play chess…in the afterlife. It’s like eating poison. Truly, eat healthier foods. 

I think the keto gummies that I see advertised on the forums might increase your ELO rating.

Depends 

In otb blitz it seems to have a positive effect but in longer games may cause problems 

idk but do you use the app, it helps me save money im poor rn

No, but Stockfish will.

Magnus Carlsen eats stockfish regularly.
