Smooth move! That rush is interesting and worked out, congrats! But it's a big risky. If he had spawned a runner instead of a soldier and saw your rush he could have taken the runner and a soldier, moving up his heavy also. It likely would have ended up as a loss.
But then again, people as P2 rarely spawn a runner so it was a good bet that he wouldn't spawn a runner and that he would move up his soldier instead of going around the back which is also less often done.
(I like talking strategy, it was a great move, very fun!)
