Does this have a name and how do I counter it?

When I play as black, I tend to go for the King's Indian Defense as an opening; but a guy at a chess club I go to has played me enough times to find out how to pick me apart if I play it. So I try to avoid playing it now. He has his favourite opening, but I've yet to work out a decent way to counter it.

Perhaps I'm not looking hard enough, but I can't find a name for this opening on the internet, or any guides on how to play against it. If anyone can tell me what the name of this opening is I'd be grateful.

Usually I move my bishop to b4, in order to pin his knight in place on c3; but that aside, I don't see much I can do to gain the advantage. I realise that I need to sacrifice some pieces to break down his control of the centre of the board, but I have no idea how to go about doing it in this position. Better still, are there any ways that I can stop him reaching the position in the first place? Am I actually better off sticking with my beloved King's Indian opening?

I have only been playing chess regularly for about a year, so my chess theory knowledge is limited. Any help is appreciated.

Are you playing as Black or White?

A line from a 1. Nc3 opening:

1. Nc3 e5

2. Nf3 Nc6

3. d4 ed

4. Nxd4 Nf6

this is the four knights game, PQ4 variation. only in different move order, that is why you can't find it if you are looking for the Nc3 name of the opening

according to the game explorer 2... c5 looks like a better move for you... start taking the centre for yourself :)

perhaps right..!!!

black's thoretical best move is not to play 4...d5 but 4...exd4 instead!

 I like that move. Could I also play c4 in order to stop him moving his knight up and allowing me to have another piece attacking d5?

It's rather amusing to find my friends on chess.com asking other people how to beat me. I'm not even that good...

This transposes into a Four Knights Game.  Here is a nice trap with this variation.
