Strange game.  This ultra open position and the quick destruction of an equal opponent was something I haven't seen in a long time.

If you see mistakes, both tactically and positionally, for both sides, I'd love to know!

How would 2. d5 have worked?

Yes, 2.d5 is playable, just part of this opening.

3...Nb4 is a waste of time

8...Na5? Black had to play Bxf3 and 9...Nxe5 to play much longer.

How did u do that,put the game here,as in post it here?got no clue.

There were tons of mates in that game, but like I said, I wanted to see their king side pawn push.

To post games:

When posting a comment, at the top of the box you see buttons.  The far left button is a chess board.  Click that and it lets you choose between diagrams, games, and puzzles.  To post a game, you can just move the pieces manually, or you can download the game from your games archives.  When you download the game, right click on it and choose "open with" and choose note pad.  Select it all and copy it.  Then, in the game diagram window, you can copy it in a box for "pgn."

I hope that's clear.  If you're on a mac, I have no clue how that works.

4...Nb4 ? 'wastes a turn' : it's right, but from the person that played 5.a3 it sounds strange. Maybe 5.Bd2.

7..dxc4 is by no way superior to the game : White keeps the material advantage, a bit of development and Black trades queens, which considerably reduces the potential for swindles.

8...Na5 ?? : aaarg ! (8...Bxf3, cf. lukesnyder's post)

18.Qc5+ probably mates in a few moves, but if you don't want to dive in tactics trading is good also.

The end is a real slaughter, and the sight of so much blood should make your opponent resign on later games (depending on time control though).

And the idea behind ...d5, in the move order 1.d4 d5 2.c4 Nc6 (so it's rather Nc6 the strange move - I usually play 3.Nf3 and the Nc6 isn't really well-placed) is 3.exd5 Qxd5 4.Nf3 Bg4 with some sort of attack against d4.
