why is so bad to smoke for a chess player?

BWAH-HAAaaa!!!! A-HAAaaa!!!
That's hillarious!.... Hey, Progressant,... smoke 'em if you got 'em... and and make sure you eat plenty of those egg-yolks in your avatar, too!

Smoking is bad for every organ in your body, including your brain.
Inefficient blood flow and metabolism prevents your brain from operating optimally. You can be a smoker and play chess, but you can perform better at ANY activity if you do not smoke.... And as to Cannabis? Cannabis has many effects, both positive and negative, but improved memory and increased focus are not among them.
"Dave's not HERE, MAN!"

Nothing actually.
They have a LOT of cholesterol but eating WHOLE eggs, even 20 per week actually tends to increase HDL (high density lipo-protein) or "good cholesterol" without raising LDL (bad cholesterol.
It's kind of an "old-wives-tale".
It's good you should bring that up.

kyle dodge told me that in colorado that smoking is not very common
but then he met his wife Jen in VA and then he saw smoking to be cool in VA

I first went to Virginia on business when smoking bans were just starting to pop up all over the country, back in the '90s. Smoking had already become socially unacceptable nationwide... or so I thought.
The minute I got off the plane I noticed there were ashtrays EVERYWHERE! And I mean everywhere! Restrooms, bus stops, park benches, fast food counters, banks, hospitals. HECK, these people smoked in CHURCH!

What's wrong with egg yolks?
Nothing, that's where all the vitamins are. They were considered 'unhealthy' for a decade or so but then that was nixed.

That's the area tobacco comes from
Yeah, you ain't kiddin'! It was a huge part of the Virginia economy. I was staying at a hotel next to an enormous cigarette factory. It smelled like cured tobacco for MILES around, you couldn't get away from it. Luckily it is not an unpleasant odor (it's when you BURN it that it smells like (expletive deleted).

Yeah, thank heavens.
Know what? My whole life, for decades, I avoided eggs because of the cholesterol scare. Finally, once I was pretty old and was on cholesterol lowering medication anyway I said screw it, I'M EATING EGGS! Now I eat 'em all the time and I love 'em!
Here's the punchline: I always had chronically low HDL (the good cholesterol that actually tends to clean up arterial plaque). No amount of excersize or fish oil helped (must be genetic). After my new egg-heavy diet my HDL went way up!! Toward the high end of the normal range!
Cooking tip: I always wondered why the scrambled eggs at the diner were so much better than mine, I mean an egg is an egg. I finally figured it out. I was overcooking them. Now, the second they start to set, I get them out of the pan and onto the plate immediately. Not runny, mind you but just barely set.
Moist and flavorful... YUMM!!! Top chefs say don't add anything, espacially milk, maybe a little water if you must. I don't add anything. It's all about the timing. Don't cook 'em one second longer than you have to and get them out of the pan to
prevent further cooking.

PapaGeorgie-
Outstanding! Good for you... It took a cancer scare (false alarm) to make me put 'em down. I had cut way down years ago but still smoked a few daily. But I had a persistant lesion on my toungue (turned out to be bacterial - related to dry mouth during sleep) and that was it, man... I'll never put another cigarette in my mouth.
Any weird side effects from the chantix. What was it like? How did it effect your mood, etc.?

Smoking is never good. Knowing u are smoking while plaing against me I would kick your king as hard as possible

Punchline? Is this a joke? Any-who, good info.

Actually, nicotine sharpens the intellect. On a very short-term basis, though. I guess it's not worth it in the long run.

*Sigh*
The word "Punchline" is used here as a figure of speech... a metaphor not meant to be literal.
It is intended to impart to the reader that they are about to read THE POINT OF THE STORY... You see... Oh never mind... You're from Texas right?
I understand you guys voted for change... HERE'S THE PUNCHLINE: BOY, ARE YOU GOING TO GET IT.
P.S. Maybe next time just address my screen name or reference the post number (#) rather than take up half a page to post an eight word message.

I wouldn't bet on this. Actually nicotin-addicted people are at a 'normal' level while they are on their drugs. Thereafter they are not. So yes, nicotin gives them a push or boost but only to a level they had without using drugs at all. There are studies about this, they can explain it way better than I did.
op didn't specify what kind of smoke..Pot has the benefit of making you more creative for a while. But I guess one would blunder more often or fall behind on the clock
