First game I expanded and tried to keep up with ling/spine. While I tek to spire to delay. He atacked with zeal/stalker.
Second game I was afraid of him to expand since I knew he was doing the same thing, I expanded when I saw him do it, I had a mix of ling(mostly)/hidra/roach/spine , I harassed with muta but by that time he just charged and killed me with colossus/stalker/zeal.
