In my opinion, I would suggest trying out old strategies as the opponent might get caught defenseless and helpless. They would say, "What, this strategy still exists?", "What, you expect to destroy me with this strategy?". Eventually unprepared, they would lose.
I ONCE defeated a Korean player with the England Knight Rush. I guessed he expected me to send crossbow-men & vicars, which I didn't; I stole his entire load of firecarts. He was speechless.
