Recently I've been really taken with the idea of creating my own building triggers using Day[9]'s systematic approach.
Trigger, If he goes 1gate-sair into expo.
I decided that I wanted to use hydralisks with +1 attack and speed. I also decided that I wanted the game to go on as long as possible because of the amount of macro protosses loses by not going FE. I also decided that went it comes time to take his third and forth that my hive should already be done along with drop.
The evolution of a building trigger in 4 games.
Building Trigger Game 1

So using seans advice I decided on four things I wanted at the exact same time , +1attack-speed-range-overlord speed
Game 2
+ Show Spoiler +
This game I decided that instead of two dens I would get a faster spire for scourge along with drop so that when protoss feels the need to move out and attack my 3rd and forth I would have lurker/scourge defending while I dropped his main
game 3
Game 4

This is the finished product of my building trigger at the C level of iccup. Complete domination begining to end knowing everyone of his moves and all the while layin a solid foundation for good upgrades/drop/ultra/ling and of course 8 hats
Day[9]s Insightfull pod casts are a must for any avid broodwar fan OR player!
