I played a pretty amusing PvT. My planned build was a mothership rush, my opponent's planned build was to 3rax marine+scv all in. Not quite the best formula for success.
I got gas before my first gateway, which means my gateway was just finishing as he was moving down his ramp with about 8 marines and 6 scvs. I started throwing all my chronoboosts onto my gateway to get sentries out asap, and begun a second gateway. He gets up to my ramp, and my first forcefield goes down. My second sentry pops out just a second or so before the first forcefield expires, and the second forcefield goes down. My stargate finishes and I decide to get a voidray, since I had the money and just needed anything to hold his attack. My second gateway finishes another sentry for the third forcefield, and he's starting to get impatient, which actually buys me enough time to survive. He moves his army away from the ramp and scans it so that he can start firing at my gateway, all the while streams of reinforcement marines are coming in. My forcefield expires, and I have no sentry capable of putting down another, but he's busy trying to kill my gateway. His scan expires, the gateway survives, and he rushes up the ramp just as my fourth sentry finishes, which barely manages to block out some of the army. He finishes off the gateway and I have to defend with my poor probes as he stutter steps and micros his marines.
My voidray pops out and I do barely defend the attack. Warpgate tech finishes and I get a stalker out of my one gateway and move out to harass his base. Even though he had enough marines to kill both my units fairly easily, there's not a lot pure stimless marines can do to them as long as I'm paying attention. I make him cancel his bunker and kill a depot, and we go back and forth a little before he decides he wants to make his second push, this time with 16 marines and 6 scvs. My entire army at that point, a voidray and two stalkers, respectfully move aside as he moves down his ramp. I tried to pick at the army a little but it was clear that wasn't going to get much done, so I counter attack. He doesn't care.
He gets up my ramp, my base completely defenseless, runs into my mineral line, and then suddenly mothership. 14 cloaked probes decimate 16 marines and 6 scvs, my counter attack is wrecking his base, gg.
