why  do they call cheese?
Any other words to say?

For TvZ, a 9 supply scouting scv will be able to tell you that the zerg is doing a 6pool rush or not. from there just complete your wall up and it will be completed in time before the 6 lings get to you.

some points that can help to delay the lings are.

1. use the scouting scv to disturb his mining time by atking the workers. 6 pool requires all drones to be mining without downtime to get 150 minerals to hatch 3 larvaes the moment spawning pool completes. if u make his workers lose mining time, you have gained some fair bit of advantage here. 4 lings compard to 6 lings in the early rush.

2. use the scouting scv to patrol his chokepoint, it will force the lings to atk the scv buying you some time (2secs roughly).

3. if they ran past your patrolling scv, just take that scv to atk his drone again. u will cause him to micro more and if he doesnt focus, he could lose a drone in the process.

4. change your build order once you scouted that he had indeed 6 pooled, build your 2nd depot sooner to complete the wall and pull 2-3 scv to repair the building as your marine is in progress, once that marine is out the lings will retreat.

i've done these sort of def against 6 pool rush in 1v1 small maps before, definitely not tough and the changes between supply and barracks build order doesnt really affect it much. ive always been doing 9supply 10rax. once you see that the lings retreat, with your economy advantage, go for hellions to harass and if baneling is the next move, go mech to tank the banelings. hellions does the job without wasting gas in which you can tech to banshee/thors and its over for them.
