how to stop the Reti?

hi everyone, I would like tips on how to stop the Reti opening. My best friend uses it and he defeats me most of the time and sometimes draws( he beats everyone else in my school badly with it). He is a little better than me overall, but before he started using the reti I could defeat him a little less then half the time. Well the reti starts off with nf3 and is played by white. After that c4 is played. I have had serious problems with it and I need advice. I have used numerous openings and have only defeated him once with one draw in the past 13 games. I am really tired of getting trampled. Please help  

I think you should watch this video on the Reti and see if you could try to learn it first: http://www.youtube.com/watch?v=YHDlA3nCyl0

Grakovsky is correct, learn what the Reti is all about. When I was playing the Reti the most difficult response for me was the King's Indian Defense.

this is how I always play it, but you do have to know the slav defense since 3.d4 transposes into the slav

Okay...

You can't, the reti is unstoppable....

Play as white 

No idea why this thread was brought back up, it is almost 12 years old.

That said, your response is wrong!  The Reti can be avoided.  Do not play ...d5.  Problem solved!

The Reti, by definition, involves Nf3 and c4 by White with no d4 and d5 by Black.  Order does not matter.

For example, my over the board rated game last night was a Reti (I was White) after 1.c4 c6 2.Nc3 Nf6 3.Nf3 d5 4.e3 Bg4 5.b3 e6 6.Be2 Bb4 7.Bb2 Nbd7 8.O-O O-O ... 1-0 (44).  It does not matter that the first move was 1.c4, it was a Reti.

So as Black, the way to avoid it is do not play ...d5.  For example, 1.Nf3 Nf6 2.c4 c5 is an English or 1.Nf3 c5 2.e4 is a Sicilian or 1.Nf3 c5 2.d4 is a QP Opening or 1.Nf3 Nf6 2.g3 g6 3.Bg2 Bg7 4.O-O O-O 5.d3 d5 6.Nbd2 c5 is a Reversed Kings Indian or 1.Nf3 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.d4 is a Kings Indian Defense (5.d3 is an inferior version of the Botvinnik Variation of the English - better to be used against 1...e5), etc.

So yes, the Reti can be avoided, but then there are other lines you have to be willing to deal with, like the English Opening.

The same goes for the English Opening, you can avoid the English by playing an early ...d5, but then you have to be willing to deal with a Reti or Double Queen Pawn opening by transposition (White's choice between the two).

@ThrillerFan - beg to differ, the Reti works on the same principles whether black plays 1. ..d5 or not, though I agree the main line is bad for black.  I play the Reti myself in tournament play and it is both rock-solid and versatile.

Capablanca didn't play 1. ..d5 in his famous 1924 loss to Reti, but he lost all the same.  The Reti is where white plays 1. Nf3 followed by 2. c4, regardless of what black's reply is (except for 1. ..e5, where you just take the pawn with 2. Nxe5 and treat it like a gambit).

The issue with trying to avoid the Reti is that any which way you do try to avoid it, you give white the option of transposing into favorable lines of other openings, such as the Queen's Gambit Declined.

To contend with the Reti as black against a Reti-style player, you must embrace Reti's style of play as black.  Accept the open center, and attack across it just as white does.  Bait over-extension of the queenside pawns and eventually undermine and destroy them, in the way white would destroy black's pawn center if he does play the main line.

The Reti Opening proved that black can't force a closed center.  What makes the Reti Opening so strong is that black must concede the opening's basic premise, or else be weaker for it.  The 1924 New York tournament where Reti rolled out this system demonstrated this clearly.  Those who tried to avoid the complex, tense positions that Reti demanded lost (Capablanca, Alekhine, and five others all lost to it), while those who embraced the sharpness of it managed to handle the complications (Marshall and Lasker both beat it).

I don't think there is such a thing as "how to stop the reti" the Reti is a positional opening and it's not agressive, it's very flexible and you can transpose to anything with it. Idk why you think it's annoying, just try to transpose to the line you play against d4/english opening

since you plau Sicilian c5 could be good, i play KID so I play Nf6 and g6.

\As I said mainly transpositions

it's safe cuz of how many pieces defending it there are (knight, rook, bishop,queen) and because of how actively you attack and defend
