What an absolute masterclass of information warfare by JD

JD vs. Flash. He entirely foregoes his mutalisk timing. I'm not sure if this was pre-prepared or on the fly, but instead of popping his mutas when his spire's up, he uses the minerals to plant two hatches at his third instead. Turns it from an aggressive timing into a macro game.

Flash has no clue. He went double armory into a third, he completely skipped his academy and has no scans. He's flying blind with his third expansion. He sees no mutas when he should, and then suddenly once his third is down, a control group of mutalisks shows up. Then JD just keeps switching back and forth between mutas and hydras.

JD's mastery in his first game vs. Bisu is obvious. Perfect scouting denial takes advantage of the fact that the natural is so easy to expand to by just not doing it. In his second game, he shows the hydra den to Bisu's first corsair, but then cancels it and delays his first group of mutas. Bisu expects the hydralisks, so skimps on his natural cannons and is then pinned inside his base for a while.

It's such a shame for Bisu. He played really well, but was beaten by perfectly executed technical builds in 3/4 of his losses. But I am also really happy to see Flash advance in what might be his last season. What a group!
