1. What the heck?

Through thick and through thin, all out or all in,
And whether it's win, place or show,
With you for me and me for you
We'll muddle through whatever we do
Together, wherever we go!

2. Initiative?
Surprise! There isn't any. All combat is simultaneous.

3. What is the sequence of events?
a) Say what you're gonna do.

b) If you said fight! or defend! or another action that is not I move!, resolve that.
b2) If you're fighting someone, roll a Contested roll of your weapon skill against their weapon skill. You do not need to roll separately for everyone you're fighting in a round (yes, you can fight everyone you're engaged with). Just roll once and post it, and I'll compare with everyone you said you're attacking, as well as everyone who's attacking you.
b3) If you hit, roll damage.

c) Now, if you said Move! in any way back in part a, resolve that.

Then you rinse and repeat until the fight ends.

4. Isn't there some fancy nonsense about being on a horse?
Yes. A mounted man can move and fight simultaneously, because the horse does the moving, and you do the fighting.
Fighting a guy on the ground from horseback also give you a +5 to your weapon skill. Not too shabby.

5. How do contested rolls work?
To be successful, you need to roll under your skill, but higher than the other guy.

6. Is this where my character finally dies?
Probably not! If you are incapacitated, your opponent gets final say over whether or not to kill you. If they kill you, they don't get to ransom you from your house or take your stuff. Hell, they might even be thrown in prison! So it's not very likely. If we end up doing the Crusade game, it gets a lot more possible.
