Hey, guys! I enjoy watching pro games although I don't understand most of what's going on in the game. But sometimes I meet new moves which I haven't seen before and are not reviewed in books or databases. It's always useful to play some new moves in your games to stay creative and fresh

Here is the game
White: Chang Hao 9p
Black: Wang Lei 6p
Event: China 6th Weifu Cup round 1
Date: 2010-09-01

It's always fun to watch Chang Hao's games as he always avoid common patterns.
In this game pay attention to move 6. I don't really see an idea behind this move. To me it looks too early kind of aji keshi. What do you think guys?
I'll keep posting games to this thread so stay in touch

Move six is actually the move recommended by Go Seigen in response to the orthodox.

It's not aji keshi. Actually, Go Seigen proposed this move to create aji in the future after the attachment at 10. It solidifies the enclosure, but erases its external power.

Oh, really? I would never think Go Seigen was the one to introduce this move. Right, Nagano, w forces b to take the corner for influence. I just don't like to set my position too early in the game, I like it to be flexible. With this move you kind of open your cards saying you want influence and not gonna invade the corner. Anyways, I have to remember this move, might use it later in the game.

Ok, here is next game.

White: Zhou Ruiyang 2p
Black: Tao Xin 3p
Event: China 19th Tianyuan Title round 2
Date: 2005-01-29

Move 6, white makes The four-space pincer. Common answer for black is to press at A with the knight's move, so overall for White to stay further from Black's thickness is better. That's way black played unusual 3 space jump, check out move 7. I checked several joseki dictionaries and didn't find anything related to this move. What do you think? Have you met this move before?

It's slightly off-topic, but move 92, E2 - is that a common killing technique against san-san in that sort of double wing formation?

I'm not sure. It wasn't common invasion by black, rather he tried to exploit bad aji in corner. So white secured the corner and black gained outside influence. So in normal conditions where white is strong, I believe there is no invasion in such formation.

during his prime cho hoon hyun commented on that move as:
"how can that be a joseki? it has no purpose but give your opponent points."

92 does seem to be a common move to defend when black enters the corner for aji purposes. I've seen it used a number of times in this sort of position. Off the top of my head, it appeared in the game where amateur Han Taehee beat Lee Changho. Here it is:


I assume you are referring to the move in the first game, recommended by Go Seigen?
