There is an old song called
"Thee Gambler" that goes like this (snipped part), by Kenny Rogers if I am not wrong.
,
He said, "Son, I've made a life
Out of readin' people's faces
Knowin' what the cards were
By the way they held their eyes
So if you don't mind my sayin'
I can see you're out of aces
For a taste of your whiskey
I'll give you some advice"
...
"If you're gonna play the game, boy
You gotta learn to play it right
You've got to know when to hold 'em
Know when to fold 'em
Know when to walk away
And know when to run
You never count your money
When you're sittin' at the table
There'll be time enough for countin'
When the dealin's done
Knowing when to hold'em, knowing when to foldèm are usually part of your ability, training and experience when playing poker or other games that have some math to it, my question for the forum is how do you know it is the time "to walk away" and I also hope that you never get to the point that you need to know "when to run".
