I recently joined the RT ladder, and ran into a large map with widely varying bonuses (China):

Although I've now seen the map, and will make better starting choices next time, I'd like to see some good games on this template. I don't know how to select RT ladder games that use a given template, and it seems that either this is a rare template, or I am very unlucky.

Can anybody give me links to good China games?

Also, is it true that RT ladder games vary in their frequency, and are there other rare templates?

nope, every template should have 10% frequency.

just played a game on that template

you can focus on where NOT to expand and which picks to choose first and how to spread if you're a beginner

Thanks for the link, and the advice.
