Lay down turrets so as to stop ht and reaver drops since those suck.
Get turrets in time for dt rushes, since a comsat requires a separate cc.
If he isn't that good, a fun strat to use is firebat run-by probe kill -> siege tank drop probe kill -> nuke.
Another fun thing is building raxs in bases adjacent to his, then floating over and building firebats to kill probes.
If you guys have the time, do a BO3 and have like match one on fastest, then on normal, then on like bgh or something for tie break.
Edit: Another thing you can do with terran is rush an eng bay in his base and float it over his mins so he can't send probes to mine.
