You should use
the Korean honorific
Seousaeng-nim
when you speak
to Lee
because his performance
on the goban
needs this recognition.
Just think
that he was
able to fight
against cores
which were
more than
one thousand
and to win
one game.
So try to find
an analogy
to realize
what he has done
and you will see
that what has been learnt
in Korean
will be
usefull
for you.
