As a mid level player who has used this a couple times in their best wins against superior players, is the quicker castling not a factor in choosing this opening? That seems to be the key to me on the conspicuous bishop move. If white plays e5 you instantly castle.
Why is the Snake Benoni so rarely played?

It is certainly “a” factor, but the general consensus seems that the trade off for a bishop
hampering the queenside development outweighs the benefits of castling early.
i consider the snake maneuver in the czech benoni to be better than the regular snake, if only because matters are less clear in the former.

this does not look fun at all, black can delay playing bc7 but d6 immediately is still the threat, and retreating to f8 via 0-0, re8, bf8 seems an entire waste of time vs going for g6 bg7 right away. if black goes for ne4 and qf6, white can even sac a pawn and blacks position looks totally incoherent.
At the highest level isn't the benoni considered strong for white anyhow. Then taking away a very strong bishop on g7 would be even weaker. I don't know. I like the benoni though. Maybe a surprise opening at top levels?
So, shouldn't an English (reversed for White) Benoni be even harder? Now, getting that as Black (and add the Snake) shouldn't be an easy thing to do...should it?
