Tenuki after 3-3 invasion? 66 NHK 2nd rd., game 5

[Uberdude]

Tenuki being a good response to shoulder hit in a decent chunk of cases is one of the main lessons from Alpha Go (but also it shoulder hits more so maybe the preponderance of these tenukis are in reply to the new shoulder hits). Here's an example from teaching tool analysis of a Master vs pro game, or there's the standard opening of AG Zero as white vs AG Master: e g. http://www.alphago-games.com/view/event ... /6/move/16. The pre-pincer 2 space jump saying "go on, split me and I'll attack your heavy wall or at least settle in its shadow" is now a standard part of the go vocabulary e.g Shin Jinseo yesterday move 39 after a push up http://www.go4go.net/go/games/sgfview/77393. Or directly move 46 http://www.go4go.net/go/games/sgfview/72995. Master vs pro example http://www.alphago-games.com/view/event ... 10/move/34 . Note that while locally a tenuki these responses are not really a global tenuki as it preemptively reduces the value of the block as followup from the ignored shoulder hit (tenuki to less obviously related part of the board is rarer).

ELF agrees on these kind of tenukis:
