Pool Questions - Group Conflict and Resolution

[JamesDJIII]

Hi there!

I GMed The Pool for the first time yesterday night. It was all I had hoped for, though I did make some mistakes. Also, I can't wait to see what the players will come up with next.

I've been reading posts about the Pool. I've read the rules before, may times, and I am interested in how it Actually Plays. 

One of my many questions is, how to do handle group conflicts, like a multi-participant combat? Is the procedure and mechanics for it up to each group and GM? How about some concrete examples?

Thanks in advance,

James
