Most competent players
have a flash intuition
of the right move.
They spend their thinking time
Just validating their choice.
Amateurs often fail thereafter,
not because of wrong intuition
but because of poor execution.
Do not confuse the two,
and do not get discouraged.— Living Go (@osmoticferenc) February 17, 2021
