How long were your games taking? From what I saw, pro games took less than half an hour because they knew how to press their advantage but amateurs would play it safe and build up a lead before their final attack. I have seen this pattern in other games too.

Depends on the map but since you mentioned half an hour I'll assume you're talking about arabia 1v1. Didn't really notice a difference between pro/amateur game lengths except in the instance where someone really new just took forever to get going. Game average was around 30-40 min., but lots of variation.
