Some Newbie Questions

[Aman]

Played our first game of the new Melee today with my 10yo son. My first game with the new edition, and last game with my old stuff was about 15 years ago!

Anyway, definitely rusty and there may be some new rules or changes I'm acclimating to.

1) Is a character two hexes away from someone with a Pole Weapon engaged? Yes, they can be attacked, but the Engaged definition on p.5 & 9 both say you have to be at one hex.

2) I assume that if you are disengaged, you can't move thru hexes that would result in being engaged, i.e. the three front "F" hexes of a humanoid. I also assume that you CAN move thru Side and Rear hexes [altho that seems a bit optimistic to me in real life, I understand that it is a "swirling melee" and the opportunity to scooch by someone not looking may arise].

3) Pursuant to the above, a fast-moving elf moving second ran completely around a pole-arm wielding fellow who was two hexes away, and attacked him in the rear [with MA12, he could move 6 hexes and attack]. I don't see any reason why not in the rules, as the elf didn't even go thru a F hex of his victim.

4) If I force a retreat on someone whose back is "literally" against the wall, there is no penalty that I can see. Am I missing something? Does anyone use a penalty for such a situation, like a Dx3 roll v. stumbling or something?

We only used melee weapons today, including a Javelin. Will be adding thrown weapons and then missile weapons. Are there some obvious questions or cleanups that I'll be asking about in a couple of days?

Someone knows...

My son enjoyed himself, and is looking forward to entering the arena again.
