I have a bunch of questions about charge. Any comments are welcome.
1) Do you have to charge using the straightest way?
No. Any movement that results in base-to-base contact (not, necessarily, in CC, as some weapons and/or models have reach) is considered a charge. However, you may not charge a model arther away, if a closer model is in LOS.
2) Can you engage more than one model into charge (speculative moving from side - not the shortest way)?
A highly improbable situation, as you must engage the closest model. Further, I can think of no situation where I would, actually,
want to do that.
3) Can you charge model behind corner? - Not in LOS at the start of movenent. Or do you have to move around the corner - stop the movement action. And charge as next action?
See Question 1.
There are several rules that are ambiguous, and are unclear. I admit, here, that my understanding may not be complete.
There are rules that come up that are, sometimes, forgotten. Remember that a model may not pass between two enemy models, nor an enemy model and an obstacle unless there is a 4" (10cm) gap, unless the enemy model is already engaged in CC.
FAQ guys, feel free to correct me if I have gotten any of this wrong.
