With Virtual Greyhawk Con 5 coming in a few days, and I'll run a Shield Lands games using an Alpha build of my Hawk Tales Rules, a pdf with some of the rules might be useful.

You can download the pdf here (1MB):

It covers:

The Combat Round

Actions and how a combat round is structured.

Initiative 

Who goes first and how to try and get ahead. Surprise and Interrupts. There are more ways to grab the action in HTFRP.

Attack and Damage
How Attack and Damage  rolls are calculated and even a little snipped on Friendly fire. I might need to write more about the "Anna Doctrine" into the rules..lol.

Defense Roll

The last bit in this little sample is about the Defense Roll. It is a way to lessen the workload for the GM and let the player roll the enemy's attacks as defense rolls.
