I don't know the exact details but im pretty sure there used to be a rule in proleauge that if you came out twice in the same match you needed to play a different race, as july had previously played zerg in the 2v2, he decided to go terran to play vs chojja.
July ops for a sparks terran, sync style, getting +1 amour for his marines. Chojja scouts this and prepares with 8 sunkens in a perfect concave, along with ling support. July scans, shows his balls of steel and attacks with his control group and a half of marines. With some really impressive micro, july breaks a sunken line that shouldn't be broken and wins the game.
I just remembered a game, a PvP, where one player went reavers, and it turned out to be a base trade, and the player with the reavers built a hidden pylon, and the other player was loosing his main, but had less dragoons, so he couldn't defend, and the reaver was defending the pylon, and the other guy saw the reaver, and gg'ed. And the observers showed, that he actually had 0 scarabs, and that it was just a bluff, cause he didn't have enough money to build scarabs.
Hive tech in ZvZ is always incredibly unusual, especially when its not forced. Massive Muta/Devourer armies combined with roaming defilers that can cause thousands of damage with one spell makes for a fantastic, unforgettable, nail-biting game.
Yup, that's the game. I've made the formatting and I've found a compilation VOD "10 Years Star Age," some other ridiculous games in there too. I know I've watched all those episodes, but I can't remember the games exactly. The description on the video is basically like this thread.
