Nice fighting game from Keigo. That UL joseki where white gives away the corner for the ponnuki blew my mind. Surely, it is a horrible result locally. I wonder why Park played it.

That ponnuki joseki is one AIs tend to like (though weaker/low playouts onces sometimes do it when the ladder isn't working!). Certainly black has more territory, though bear in mind the corner isn't aji-free: with c17 cut if black wants to keep the corner he has to answer submissively and white can get some forcing moves, or else if atari white can make a tripod group later.

And just to post the result: Chen Yaoye won the cup.
