usually you attack on your right of the board, and he attacks on his right of the board
is this opening STRATEGY good?

I don't really know because I usally rate strategy after seeing a couple of games with it. Try posting some of your games or moves along with this. Personally I want you to experiment with it.

Mebeme> you trade a bishop for a knight, giving your opponent an pair of bishops for a supported safe knight on d5 or e5 as white
It depends on the details, but the idea can work. For example, it's been used even at the super-GM level in some variations of the Sicilian.

well..imo 7Nd5 is much beter.
why giving a bishop for a knight??
your bishop can only go to e2 and blaks' bishops can fo almost everywhere
nice square for the knight on d5
no castling for white [and this will hurt!]
xD im talkin' like expert.
LOL!xdLOL!

Dark_Daemon, 7.Nd5 is met by 7...Nxd5 and now you've lost that beautiful square for your knights. That's not to say it's a bad move, but it certainly doesn't give you the strong central knight you get in the 7.Bg5 lines. 7.Bg5 is the mainline.
you trade a bishop for a knight, giving your opponent an pair of bishops for a supported safe knight on d5 or e5 as white, d4 or e4 as black.is it good?
