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.😉

The probable explanation is that he ate at McDonald's too and it made him play like that.

That must be why the McDonald tribe is nearly extinct.

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.

let the mcdonalds flow through your veins become the grease

Depends 

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