I am having a terrible time against the pvz immortal sentry. Sometimes I crush it, sometimes it owns me like no tomorrow, but I can't really figure out what goes wrong, I feel like I'm doing the same thing.

And could anyone help by telling me more about this build? I usually go for a ling-roach approach with emphasis on many lings after droning up heavily when I see it coming.

Sometimes it comes kinda late (are these people just bad?) and sometimes a lot earlier, like in the game attached.

This guy is of course also blocking messages to him so I couldn't ask for practice against him either. I hate that feature.

I just have no idea what to do.

Problem I think in this game:
Droned a little bit too hard. Missed my potential infestation pit timing by ~25 sec.
Waaaay oversaturated on 3rd, didn't realize I had that many drones.

Question, when should I start making units when I have identified the build? Do I have time for infestors? This hit right before 12 mins.

This is master/grandmaster level for SEA.
