Openings for Beginners

Hello, again. I went to Berlin recently for a holiday and, while scouring the Kreuzberg district in search of some outdoor chess boards I found a club that specialised in chess-boxing? I am most perturbed as to what this sport is and if any of you can tell me I would be most greatly. But now I am back from my ventures and we may resume our series of short tutorials. This time I thought we might again have a look at the Greco mate and what to do if one of the following another move other than Nf6 or d6 occurs. This set up is known as the Soronevki Variation. I hope you enjoy!
