Sorry for my bad English.. I am rather bad chess player but in sport activities I have managed that max concetration is the key to reviel the power and energy that you have not even expected. I believe there is no one birnd a champion- only hard work and exploring self abilities by using mental strenght inside can let reach the realy impressive edges. And there is no way to avoid concentration if you have to improve yourself.
How hard do you concentrate?

its really about the skill level, put it this way... if i played myself focused vs careless id most likey lose to my focused self... but somedays the passion isnt there and somedays im hallucinating after being up 2 days and im trying my best to focus but if u cant see the board clearly and i dont play blindfolded chess so tactical vision doesnt matter because the vision isnt letting the logic manifest itself... my dads a good player but smokes spice and hallucinates so i dont judge him because im even worse when im high... but as far as chatting and playing it paves the path for my thoughts like an outline and i tend to combine ideas better because i aknowledge more assuming were chatting about the game...

I feel how hard you concentrate is related to time limit. I find the longer the games the further I analize. Having said that in 15/10 or 15/5 games I still make moves on a whim. Not that it's a good thing but lol.
When I play friends I OTB I find myself concentrating the most, sometimes almost over analizing and making a poor move due to in depth plans based off their moves that in my head I make for them and if said move isnt made by the 3rd move I am FUBAR'D. Weird eh?

Yeah...that darn hand has a mind all its own. Before you know it your center structure has been broken and your Queen is running for her puny little life.
Just curious! :D
On another note, I've searched around and have found some answers, but they are mostly a couple years old. How does one post games and annotate them? Pretty darn tired so keep it simple lol
There have been times where a bus could've rolled right by behind me and I wouldn't have batted an eye. What about you? How hard do you concentrate when playing Live? When sitting across the board from someone?
I ask because some people could hold a conversation and still run a good game while others, like myself, would probably sack a major piece.
