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?

usually you attack on your right of the board, and he attacks on his right of the board

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.

Lets set up a game! We can test it out.

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.

i have used it in otb games before , but not online,off to live chess

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.
