Quote from a lower rated player on facing my Benoni: "Grrr..I hate the Benoni! Hate the Benoni! Woof! Snarl! Grrr…" (said after losing to it for the 4th time in a row )
I guess it's because they learn lots of theory on the QGD and King's Indian, and then they get faced with the Benoni.... Kind of like the White players who learn tons of theory in the Najdorf and the Dragon, only to see 1....a6!
yay, so the moral of your story could be, study more randomly, or don't study ? ! D
I play the Benoni, I also play 1 d4. The Benoni (especially at the club level) is just fine. I've played it almost exclusively since the 90s and always reach decent positions. If Black knows what's going on he should be fine.
