Tactical moves in combat - positiong redux

I have gotten some feedback on my last post on positioning. Apparently I wasn't all that clear, so let me try again.

One of the important things about positioning is your relation to your enemy. Do you control the area? Are you able to keep the enemy at bay? To what extent do that relation shape what actions you take? The ideal is, of course, to limit the actions of the opponent.

Considering that relation, we keep tabs on whom are engaged in melee with whom. If you are engaged, your options are limited to fighting that enemy. The same is true for your enemy.

The only things you need to keep track of is whom is engaged to whom.

If you don't want to be engaged, or you want to limit someones options by engaging him (for example hinder somebody from attacking the magic user as she is preparing her spell) you'll roll dice.

Now you just roll initiative like you usually do, and if you win you now can free your options for next turn by disengaging or you can now limit that other guy by closing for melee and engaging. If you fail, that was all you did that turn. I hope your armour will take the blow!

I hope that was clearer.
