(allout) is bad Wank! Don't use it.
Here's an example fight plan that I used to use. It's called "SuperClinch" and works best with a fighter that is taller and stronger than your opponent.
1) 6/6/8 (clinch);
#Fight is Close so Hammer away!
4) 8H/6/6 (inside);
#Fighter is Winning so back off a bit
4) if score > 1 then 5/7/8 (clinch);
#Fighter is Losing so go back inside and pound away
4) if score < -1 then 7/6/7 (inside);
#Fighter is Tired so clinch!
4) if endurance_percent < 100 - 5 * round then 5/7/8 (clinch);
#Fighter is Exhausted clinch more and go for a KO
4) if endurance_percent < 100 - 10 * round then 4H/8/8 (clinch);
#Opponent is Tired turn it up a bit
4) if opponent = tired and endurance_percent > 67 then 6/5/9 (inside);
#Knockout Opportunity hammer that mofo!
4) if opponent = weak and endurance_percent > 50 then 7H/7/6 (inside);
#Fight is Still Close clinch him down a bit more
9) 8/6/6 (clinch);
#Winning by a comfortable margin so back off
9) if score > 12 - round then 5/5/10 (outside);
#Decision is locked up so run!!
9) if decision_won = true then 1/1/18 (ring);
#Losing on points so go back inside
9) if score < 0 then 6/7/7 (inside);
#Probably going to lose a decision inside even more
9) if 12 - round + score < 0 then 8/6/6 (inside);
#Need a knockout to win hammer time!
9) if decision_lost = true then 9H/5/6 (inside);
#Knockout Opportunity
9) if opponent = weak and endurance_percent > 50 then 7/7/6;
stop
Now, I wouldn't copy that and use it unless you have the type of fighter it's made for. It gives you some guidelines tho... I also use the if stun damage > 1 type of args in my new fight plans, read up about it in the docs!
