[Lord of Nukes]

If he sends his first Zealot to you, you'll have to fight it off with SCVs and usually a Marine. If he waits a little longer but you know he will go for fast Zealots either by previous experience with the player or by scouting, you can try for a Tornado Teran but lay mines near your entrance before going out to harass him, and try to do it as fast as possible regardless of how many Vultures you end up with; 2, 3, or 4 by the time you get Mines researched. Alternatively, you can micro your Vultures around your choke point, this'll work well on a map with ramps like Lost Temple. Either way, once you get some Spider Mines down it should discourage him long enough for you to get more Vultures or a Tank or two.

Remain open to any advice, TvP is my worst match-up. :\
