Building 2 Trading Posts need to be done quickly to get the base deployed, so keeping Chayton Black on the move is a priority. When the first Town Center is put up, I collect some materials already because when the second Town Center is up, I need to age up to get more units. After that it's just taking out the 2 enemy Town Centers as quickly as possible. I put Holme in the front row for the first enemy Town Center so that the enemy will attack him (Chayton Black already had his share of damage...), and Heroes can take quite some impact which means that the rest of my army can attack the Town Center for a longer time. I can't immediately attack the first enemy Town Center though before some unit reinforcements arrive, otherwise I would be butchered. And the more units I lose, the longer it takes to destroy the Town Center. So I start attacking it just before some unit reinforcements arrive.
