hmmm,
thanks for the answer, but obviously the picture (and my question) was not all that clear...
I can not slide the pk (2 wide, 2 deep) to the left, because of the lone enemy lc still fighting there against more pk of mine, sure.
When I hit the cv in flank, I did not conform to any corners and none of the cv hat all of his front contacted by a single element of mine...
So I slid far enough to the right to make front corner to front corner contact with the formemost cv (Fighting frontaly against my sp) thus giving him -1 and a qk. this is the position, i photografed.
My noble oponent held, that as I by this position, cv Nr. 2 was contacted on his full flank, but by 2 different oponents, he was not legaly contacted and thus did not have to turn, cv Nr. 3 was not even contacted on his whole flank.
The solution would have been to slide further to the right (the position I marked with the rectangles) in order to contact cv nr. 1 with the whole flank of the rightmost pk and cv. nr. 2 would be legaly contacted by the left pk (and only by him) making front corner contact, and thus cv. nr. 2 (and 3, contacted partialy by left pk too) would have to turn (in column).
thus the question to me remains, did I have to stop my slide to the right in the first legal position (for the right pk column) in corner contact with cv 1 or could I voluntarily slide further to the right until the left pk would make front corner contact with cv 2....
(I did not even find, that the pk back ranks may slide to, as they themselves did not make physical contact and where not in tz either....)
Still confused
