I'm very pro turn 16 foul in the sense of one which...
1) achives no personal gain.
2) does NOT impede any SPPs I might gain by doing other stuff first.

So, when I pull off a many dodges, GFI turn 16 foul (unsupported, just the fouler) which does not even break armour (suprise) with my only remaining player it upsets my opponent (who apparently never thought of the idea before). This is fine, they can be annoyed, I often do not turn 16 foul if I KNOW it will cause upset.

I also left them an easier TD by doing this, it made no difference to the score but would have given them tidy SPPs and more FF chance. Do they take it? no? They, who are against the practice decide to kill one of my players instead of the TD.

Sorry, who's just done that foul out of spite (rather than a duty to foul)?
