Just checked the replays:
First:
Probably that, although not sure about the very fast reaction, the dude was slow and did some really strange attacks with no reaction at all. It looked like someoneâs offrace, trying to make things, throwing random things at the enemy, there was no build, no base layout no addons no proper placements, no metagame knowledge ,no medivacs,fast raven with upgrade,many mines and weird biomech composition with a BC at minute 12. You had the game, and threw, instead of attacking a PF with tanks, go over it, attack the undefended nat and force a movement from T, or you could use your iddle phoenix to lift the tanks that were killing you.
2nd game, no smurf, again, weird build and too many banked minerals at the early stages of the game. You had that game, but didnât look at your army at all, you also had disruptors and you barely used them vs the lurkers, when you have them, you must shot all your shots at every chance you have, if you see the lurkers there, blow them, do not just send a couple of shots and run away if you have 4-5 disruptors, the same when you donât have detection, see where the spikes are, and then shot, you can kill the lurkers without detecting them.
3rd game, nothing strange, you both were pretty similar,none of you did the best build but in the end you won because the Z macro was not really good and took a bad fight.
4th game was enemy playing passive, and outmacroing you, he had around 400mmr more (it can happen sometimes depending on the hour/ranked/unranked) than you so probably was that, be passive, let the Z reach 85 drones and he will kill you with roach hydra, specially if you have no reliable aoe.
