- Many thanks, Jan van der Steen, for an excellent and comprehensive reply to my
- query about go terms.
-
- Regarding the existence/translation of "zwichenzug", I had an email reply
- also suggesting "kikashi" as the nearest. I suppose it does capture a lot of
- the idea, but not *all* of it, I think; a kikashi play may not necessarily
- be "intervening" in any sense, though admittedly it often is.
-
- As regards my comment...
-
- >>It strikes me that this kind of thing is even more common at go than chess
-
- >I would rather tend to the opposite by saying that it's more unlikely

-
- Perhaps we're thinking of slightly different things, but my experience is that
- it's quite common. Your example about distant forcing plays to set up ladder
- breakers is exactly the sort of thing I had in mind. This is common, surely.
-
- >I tried to remember a pro game with the
- >occurence of a "zwichenzug", but couldn't think of one.
-
- Well, I would have thought there was an absolutely classic case, even a
- *definitive* one, in the book-length game of the novel "Master of Go".
-
- Indeed, to a some extent, the plot even turns upon the critical move actually
- *being* a zwichtenzug; off the main battle, and completely unexpected. As I
- recall, it was a kikashi move that the player finally decided to make, as the
- current battle was slowly reducing its sente-value, and he wanted to get it in
- while it was still completely forcing, though he had left it till that time so
- as not to reduce his own options. Unfortunately, it came right at the time of
- a sealed move, so was interpreted by his opponent as being a cheap trick to
- gain advantage from the sealed move situation, in knowing what his opponent's
- reply must be. The apparent bad sportsmanship threw his opponent off-balance
- with anger, and thus may have contributed to his losing the game (though the
- angry opponent later completely retracted this implication).
-
- Anyway the point was it was completely surprising to all concerned, being well
- off the apparent battle, though forcing. Surely a true "zwichtenzug" ?
- And from a real pro game.
-
- ----
-
- Just incidentally, I suppose the modern view of such a situation would be quite
- different ? That is, that if either player wanted to gain the sealed-move
- advantage of knowing his opponent's reply by making a totally forcing move, this
- would be regarded as being quite a legitimate tactic; along the lines of
- making use of opponent's time trouble by introducing dubious complications.
- Would tournament players agree ? And remember, the sealed-move situation is
- quite symmetrical - either player is at liberty to try the tactic.
-
- Indeed, it could lead to a battle over the several moves preceding the
- time-control, as both players tried to grab the kikashi sente with successively
- more urgently forcing moves !
-
- Has this sort of time-control battle ever occurred in tournament games; does
- anyone know ?

- No I'm *not* cheating my employer by spending 3 hours a day on the net.
- I'm just using the time I would have spent on solitaire games and go problems.
