Does playing chess with your left and right hand make a difference in skill?

When we use our left hand to do things, we activate our right brain more and when we use our right hand to do things, our left brain gets activated more.

So if we use both our left hand and our right hands alternatively while playing chess on the phone or the computer or even OTB, we'll be activating both sides of our brain at once.

Does this improve a person's skill level? Many people while playing chess on the phone tend to use just one hand, So I'm pretty sure it should increase a person's strength by atleast 100 to 150 points if not more. Any thoughts?

Use both hands for every move.

(and ideally think before you move)

Illegal:

4.1  

Each move must be made with one hand only.

This also implies that peple who play with their right hand do better at chess because playing with the right hand activates the left hemisphere of the brain which is in charge of carrying out logic, decision making and mathematical computations.

What´s the handedness of the World Champions? Of grandmasters?

Is the frequency of left-handedness among grandmasters the same as in general population, or different?

Intersesting post.  I am sure after playing a few moves with your left hand and you get into a habit, your cognition will differ.  Though at the same time bouncing back from creativity and logic.

Not sure about world champions but here you can see Hikaru clearly using this technique. He's activating his left brain continuously by playing with that pawn. Learn from the Super GM guys.

Is this a joke?

Why? Is it funny?

Complete and utter bull. I really hoped that we have left the whole 'left-right brain' nonsense decades ago. Your brain will not work or develop in any way just because you're switching hands. There are a few people who are ambidextrous (me, for example) and even they don't show any superpowers.

Well I am in trouble in a couple of games so the mouse has moved to the left side and I'll give the idea a run out.

What does it cost?

Found this on a chess website: "Prof. Gobet and Dr. Campitelli have found that there are fewer right-handers in the chess population . . . " Also found this: "As far as I know 14% of all chess players are left-handed. This should be valid for grandmasters, too."

Lefties (I am one) generally run about 10 percent of the population.

• ... Mensa International - the largest and oldest high-IQ society in the world - claims that 20% of their members are left handed - while less than 10% of the world population is left handed.

Another example of the link between left handedness & high IQ is seen in Chess - which indicates that the link should be recognized as specified to visuospatial cognition. Various studies have indicated that a high percentage of chess players is left handed:

2007 - Handedness, practice and talent in chess: Campitelli & Gobet report among 104 Argentinean chessplayers: 17.9% are left-handed of ambidextrous vs. 10.2% in the control group (= non-chessplayers). [The study was also published in: http://bura.brunel.ac.uk/bitstream/2438/611/1/Gobet_DevPsyc_Final.pdf ]

1988 - The Exceptional Brain (see chapter 7: 'The Chess Mind', page 176) - Cranberg & Albert reported: 16.9% of 266 United States Chess Federation players (males + females) being left-handed or ambidextrous; among male chessmasters the percentage was even higher: 18.1% of 138 players (but not lower in male chess amateurs: 19.4% of 98 players).

That's small but noted I guess.

After about 20 years, I realized my right forearm was considerably larger than my left, so I switched and started using my left. Well, 20 years has gone by and my forearms are still disproportionate, but my left has grown some. Hope this helps.

Also recall again the rule that the whole move, including pressing the clock, must be made with the same hand.

Is the chess clock always on the same side of chessboard, like queenside (left for White, right for Black), or does this vary?

Methinks good players decide on what move to make before they use either hand to play the move on the board. 

 Does it feel as good doing it with the left hand?

Well, on one hand, yes, but on the other hand, no...
