I need a new opening for black

I just played 5 games against the same guy and lost 2, playing black both times.  My opening was kind of awkward, what could I have done better?

I realize the title may have been misleading (as if I'd made up an opening).  So I changed it from "New Opening for Black".

Game 1 play Be7 before Nf6....There is however a gambit that allows this line you played and you should have played h6 rather than Nxd5 which isn't well known.

Game2 You played d5 before castling - that was my immediate thought . Never the less you came out of the opening better - so not the openings fault here.

you shouldnt play d6 in the 2. move. Its to passive for you and there are lots of traps for black and no trap for white. So play the Main lines with nc6 and you cant lose under 20 moves. Cheers

The Philidor is okay but not for her/him! Its to passive and hard to play for black when you are Not a really strong player.

In the first game, Be7 before Nf6 is better, just to prevent Ng5. This is perfectly fine for black, fireflashghost's mentioned alternative move order is maybe a little safer if you're comfortable with the queens coming off early (usually white avoids this because black is perfectly safe and can usually get an easy draw).  

Try not to memorize these moves, that's not the point- just be aware of what whites ideas are, and you'll see how these moves are designed against those ideas. 

In the first game, I don't like 2...d6, but it's playable. Developing while protectin or attacking would be better with Nf6 or Nc3. A little book will go a long way, so I would recommend researching some Ruy Lopez.

Also, look into the Lolli Attack, that's what he started to do on you there. It involves a Knight sac and major piece activity from White.

And in the second game, I don't like how you play ...Bg4. The pin does not lead to anything and he can simply play h3 and g4 kicking your Bishop into granite. But instead you simply took his Knight, giving him the Bishop pair, so this is where you first went wrong in principle, but even then he did not have a winning advantage.

The problem started when you began dropping your Knights on the Rank 4, playing over aggressively when he can simply dodge these fake attacks, especially when you haven't developed your other pieces and Castled.

You were winning on move 15, ...Qd4 here forces him to trade his Queen unless he wants to lose more material, and then you're headed into an endgame up a piece, but this ended up happening anyways. Then you just should have brought your Rooks into open files.

In chess, the best players don't bring out one or two pieces and try to checkmate their opponents, they bring out every piece, moving it as few times as they can, until everything is active, and Castle. Then go about creating an attack.

1e4 d6 is a very novel approach requires study for black but if understood has a great psychological impact on an unprepared white player best not used in 3 day chess tho as it loses its surprise value if white has time to study at leisure

Playing d6 is a mistake because you have to defend with d5. So defend the pawn with Nc6.

In the second game taking the bishop on b5 was a mistake although your opponent didn't take advantage of it. You need to develop and castle.

Just keep practising with what you're doing for the time being.

The normal move there is N a5 and that's OK although there are those who think they can defend the attack. Someone I used to know who was a friend of Bronstein used to swear he liked the white side. Not sure how good this b5 is but then I wouldn't play the white side of that.

Think I'd take the knight. It seems to give black weaknesses.

I play the Caro-Kann Defense, and it can lead to some really good games.

In the first game, probably after 5 .... Nx d5, then 6 N x f7 may be correct. I'd say it certainly looks ok. Gives a similar position to the fried liver attack.

OK yes souravtheslayer, I certainly see what you mean. Do you agree that in the game as played, N x f7 was correct? I don't play double kings pawn openings so it's all Greek to me.

I just like active pieces. I hate passive positions. Sure it looks a bit complex or even unclear, but it is highly active.

Modern Scandenavian is BOSSMODE

I would not say you need a 'new' opening. I'd say you need AN opening. 

When it comes to openings, you don't have to re-invent the wheel. You can choose from many that will suite your playing style.

If you like these initial moves, which, I believe someone said is the Philidor, then go watch a couple of youtube videos and read about it a little so you can learn some appropriate moves.

I cannot say if The Philidor is the best choice for you or not. But there are a few that I believe may be easier for someone at your level to learn. 

Until just this week, I always responded ..e5, Nc6 which can lead to Ruy Lopez, The Scotch or maybe The Italian Game. The Scotch and Italian Game have many similar ideas and related lines. The Ruy Lopez can have some similar ideas as well.

This past week I started experimenting with The Sicilian. We'll see how that goes.
