[MA] Best dirty-fighting style for a callous weakling?

[Lord Carnifex]

To add to Icelanders good suggestions, there's one that I've ingrained after years of bar security

If A and his friend C are in even a moderately crowded situation, and B becomes confrontational with A, the proper place for C to be is standing directly behind B. IME, if there's even a moderate number of people moving around, B will concentrate on A enough (arguing, building up Evaluates against A, making Will rolls to initiate hostilities, using Body Language to try and read A) that B must roll a decent Perception roll to even notice that C is there. Meanwhile, C Evaluates B, and Waits for B to act (can one Evaluate while Waiting? I'm sure the question has been asked before - I'll have to look it up.)

Backing up your friends is well and good, but the best place to back up your friends is behind your enemies.
