Maybe i could start with one of mine:
on e.g. Badlands i like to go for a T2 Land guncom all in push, that works as follows:
-you expand normally
-build up t1 Land and transition kinda fast into t2
-go for 4-8 t2 mex, iwch depends a bit on how much pressur the opponent puts on
-build enough power for reasonable fast gun
-and should have a decently sized army by the time it finishes
-excess power now for t2 Air
-scout for enemy ACU
-push your ACU to the enemy one, either mid or one side
-still build units, as they can catch up with the ACU, and once they can't stop building them
-and put all ressources into gunships to finish th job
Advantages:
-punishes to much eco and if unscouted is almost impossible to defend
Drawbacks:
-puts you at an eco disadvantage
-can't be used to often on same opponent
-if scouted can be defended
-ACU is a bit vulnerable, but if you include some flak in your army composition that should be alright
Take all this with a grain of salt
constructive criticism is ecouraged
