Diplomat and liyue. Do they know each other well?

They met each other few weeks ago during the Go tournament in Amsterdam: http://www.europeangodatabase.eu/EGD/Tournament_Card.php?&key=G090521A
That time Oleg Mezhov (Diplomat) won the game.
It's seems that they became good friends, so recently they played lot of games on KGS. I asked Oleg about "lovers", as someone mentioned during the game, but Oleg decided to leave these words without comments.
Maybe they have some secrets :)

About the game: Oleg overplayed in his attack, but ... Li Yue misread and lost lot of liberties at the end. I showed 2 variations - 2 ways of winning that semeai for Black.

It was a very fun game!

By the way, Oleg plays in Moscow Championship right now. The results are good - he is undefeated so far!
