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
