Hey guys, I found this somewhat risky but risky opening that even GMs use. The QGD is quite normal but then, we enter the Meran system, producing gambit-style play. So, I just need some help analyzing the game so I can study this game further and any thing on the Semi-Slav, Meran would be nice! :)

The game you show is not the Meran. It's an anti-Moscow gambit.

The Meran is 5.e3 e6 6.Bd3 dxc4 7.Bxc4 b5.

After 5.Bg5, black can play 5...dxc4 6.e4 b5 going into the Botvinnik System, or 5...h6 after which white can choose the quiet Moscow System (6.Bxf6 Qxf6) or the anti-Moscow gambit (6.Bh4 dxc4 7.e4). Or black can go into the Cambridge Spring QGD with 5...Nbd7 followed by Qa5.

thank you for clearing my confusion! :)

Sadler has an EXCELLENT book on the Semi-slav.

1.Nf3 is not called the Zukertort opening, it's called the Reti or King's Indian Attack. 

You can be right or wrong. Some people will say one side, some will say other. I would say that 1. Nf3 IS the Zukertort Opening. The Reti is characterised by 2. c4, and the King's Indian by d3 and e4 (and possibly a kingside fianchetto). But at 1. Nf3, it is too early to say what opening it is- indeed, 1. Nf3 Nf6 is the Zukertort: Symmetrical Variation.

That's true. I think the official name is The Reti. 

The Reti is 1.Nf3 d5 2.c4.

I think 1.Nf3 is called "1.Nf3". That's what people call it the most, anyway. Not Zukertort.

1 Nf3  can become many openings depending on the next few moves. I think its a bit premature to call 1 Nf3 any opening yet . What would you call 1 e4   or 1 d4  ?  However, I did see that after only 1 Nf3 its called reti opening when I asked for ECO code after only 1 Nf3.

Ok, ty any help on the opening itself?

It is called the Zukertort Opening

Reti is 1. Nf3 d5 2. c4

1. Nf3 is Zukertort and 1...d5 2.c4 is the Reti
