Goran Siska: Since I'm partly responsible for the Go and Ethics discussion I'd like to point out the following joseki. (Moved from Go and Ethics by Charles Matthews.)
This is the starting position. A variation of a 5-4 joseki, with White playing tenuki.
Now
So why not play
This is the sequence Black is hoping for is (ko lock). White is completely blocked off from the center. This is what I mean by hoping for the opponent's mistakes. Black didn't overplay but the order of moves leaves more scope for White to make a mistake. Charles Matthews: Examples from pro play do back up this theory about Black's order of play.
Andre Engels: In which way do they back up this theory? If this is the actual reason, I would expect professionals to play both sequences, since their also professional opponents would never make such a fundamental error in a well-known position.
If Black actually uses only the joseki move order in professional games, I would think that there has to be another reason. My guess would be that the reason is that it has to do with the (very small) possibility that White would answer at Charles: The total number of examples Gobase+GoGod is only six (and in one Black makes a hanging connection not a solid connection) so too small a sample.[1] It's always the same order, though. Also I wonder about the diagram.
I'd certainly expect [1] Good thing I said that. Here's an example from a book by Otake Hideo, which is presumably from a pro game though I haven't traced it.
Here it seems natural for Black to fight back with
In this case White does play
It is logical to assume here that the reason is that up to
This followed, and Black's strategy adds up to a reasonable balanced game. White has two weakish groups, the one on the lower side not really being weak now since White a threatens the corner. Black has a single weak group only.
