The rule on page 28 is quite specific : "[A group move] ... cannot ... include ... any sideways or oblique movement except to line up in front edge combat." I would love to be able to do the sliding while I am out of contact but it isn't allowed unless you are sliding into front edge combat, which you aren't. This isn't about geometric ploys to prevent combat, it is about your own elements blocking your ability to get into contact.
Hi Andrew,
I understand your above quoted reasoning, but, as the Germans would say, I think you?re being more papal than the Pope !

The group is moving sideways in order to finish their move in close combat on that turn.
Agreed, half way through the move, when the slide takes place, they are not (yet) in combat but at the end of the move they are.
There is an aspect of geometric ploy about it:
I have two groups. Group 1 attacks first, moves straight ahead for and conforms to the enemy, thus blocking Group 2, which cannot then simply attack straight ahead.
If I move Group 2 straight ahead into contact first, then it does work.
Maybe I have a reason for wanting/needing to move Group 1 first (e.g. not enough PIPs to achieve both contacts this bound).
I do feel your interpretation leads to an "ugly" and unnecessarily complicated rule, that I do not think any of us (including yourself) like. It?s the kind of interpretation that puts off new players, who then end up playing FOG.
If I was umpiring a competition (which I do ), I would allow the blades to move into contact for 1 PIP.
If there is a serious number of players who interpret the rules differently, the committee should make a clarification.
