what is London opening
This is the London opening. It leads to slow, boring play. Definitely not good for player of your rating.
The London is like its namesake. The UK has bad food, dreary weather, and is cramped and old. Don't play the London; its cold, sparse, dreary and tasteless. Hop on a plane and fly down to Spain, Italy, or Denmark. Go visit Vienna, or if you must visit Great Britain, go to Scotland. Anything English should be avoided.
