Flying off orthogonally

Charles The 'flying off' feel is like this:

Flying off at ninety degrees

When Black cuts with BC (probably questionable) W1 tries to set up a driving tesuji based on White's atari at a. This is one element of many sabaki techniques.


A large-scale example.

Black 1 'at right angles'

Here B1 again exemplifies one of the most interesting 'feelings' about fighting: that rather than trying directly to cut at a (a failure, according to easy way out of a double kakari), Black should spread the struggle out in an orthogonal direction to take some wider advantage.

This concept has something to do with motare, but appears at the level of suji.



This position is from Cho Chikun - Cho Sonjin (B) in game 2 of the 54th Honinbo final (1999-05-24,25), at move 79.

Black succeeds, no doubt deliberately, in starting a complex fight, rather than just playing out a corner joseki. (One can note that not too many of the worked-out 4-4 point joseki lead to large-scale fights, if you believe the books - but that may be a problem with joseki as definitive sequences, as much as anything else.)

Sometimes the way this is expressed is of 'incorporating' other parts of the board into the fight.

Here W9 threatens in one direction while looking in another, which is a variant on the same idea.

After W1, White has an attack in the centre.

Finally here the fighting affects the opposite corner of the board.
