DO NOT PLAY THE BENONI UNLESS YOU ARE A GM!!!
Benoni is far too complex, even for 2000+ players- only GMs and IMs should be playing it. If you want something easy, how about the Dutch Defence? Or 1... d5. If they play a Queen's Gambit, I like the Queen's Gambit Declined/Semi-Slav Defence. If they play the London, mirroring them and trying to play an early c5 is a good counter. Finally, King's Indian Defence can be very strong at lower levels, and is a simple enough setup to wrap your head around. That's my advice, hope this helps!
Hi! I want to learn a n opening against d4 (as black). Someone recommended the Benoni Defense. If anyone of you plays this as black, can you please share some themes to keep in mind when I play Benoni?
