[PTSZ]

So I've been losing to 1 base terran plays lately (diamond league). I always open hatch first vs terran.

Problem 1 - Terran denies overlord scouting with marines after I scout a gas opening. Then I scout a barracks with a tech lab and a few marines at his ramp with my first set of lings. 1 reaper pops into my natural and gets pushed away by queen. I check his ramp again and see a hellion. I make roaches and lings in preparation for the first push, with 1 spine crawler at my natural. I'm anticipating some sort of SlayerS style blue flame drop.

Then he hits at 8.30 - 9.00 with 7 or 8 marauders with concussive shell, some marines, 8-10 blue flame hellions and a few scvs for repair. I barely hold the push, and he retreats with the majority of his hellions still alive (I have no roach speed yet). 1.30 - 2 minutes later he pushes again with his blue flamers, more marauders and 2 thors with scvs repairing and crushes me because I don't have enough drones to replenish my army to the amount needed.

Later I check the replay and see he hid his marauders after the barrack-tech lab opening, followed with 2x factory, with armory and second tech lab building as he moves out for the first push.

What should I be looking for to deal with this? I know an all in is coming as an expansion doesn't go down. But after him denying OL scouting it could be 2 starport banshee for all I know... So scout the ramp more often? And when should I start producing units in order to be able to hold and still have enough drones to follow up? Maybe get a lair sooner and try for mutas? I'm clueless here.

Problem 2 - This happens on maps like Xel Naga Caverns or close positons on Shattered Temple. Terran opens 2 rax, delays it slightly, and hits at around 5.30 with 7 or 8 marines, some scvs with the threat of bunkers. Usually my spine crawlers are about 75% done, so he can sometimes slip past and into the mineral line, or he can just sometimes kill a sole spine crawler by focus firing. But usually the ling numbers and queens are able to hold this off with minimal losses.

Then he transitions into 2 port banshee with cloak, hitting just after 9.00. I can scout this sometimes and put down 1 or 2 spore crawlers by each hatchery and try to get up 4 queens, which delays my lair. If the terran has poor control, I can defend this. But the terrans with good control - they start to snipe anything out of range of the spore crawlers - either the gas geysers or spine crawlers at the front of the base. As I move my spores to defend, they start to snipe queens without the aid of detection - 4 banshees can 2 shot a queen and then pull away. He continues to harass and then hits at around 11-12 minutes with a mass of marines, some hellions, a medivac and his 5-6 banshees. I'll have usually teched to muta by this time, but the numbers are too small to do anything worthwhile, and lings get minced by the ground force. Baneling numbers are low due to a lack of gas.

Help pls? These Terran high-DPS and high HP units are proving to be really difficult without the macro advantage zerg needs.
