Old Benoni variation?


If youre going to put yourself into these types of positions, you need to understand that you will need to know what to do depending on what does. So prepare to study many different moves.

After 2. dxc5, why recapture with the Queen? Isn't 2. ... e6 even better?
White can hardly try to hang onto the extra Pawn...

when i started i used this opening but id open e6 and take if he took on c5, after his move. but they just clamp down with the central pawns i dont really remember just use an engine
Engines dont explain "why".
IMBacon does have a point about being ready for many second moves by white. However, regardless of the variation of the Benoni your main plans are mainly concentrated on being able to either defend the pawn push (2.e6 comes to mind), impede further advance (again 2.e6 for a regular Benoni structure), take the center (2.cxd4, losing a tempo) or control the center (2.e6 is a candidate move, but you can also go for 2.e5). After all of that the natural plan is to castle kingside either by Be7 Nf6 or by fianchettoing Nf6 g6 Bg7. The main point of the Old Benoni is that you can end up playing a Sicilian French, at least a couple of KID variations, regular modern Benoni, or a Franco Benoni. Lots of different options for white (good options), but you have very simple plans (namely castle and wait). Also 1.d4 c5 is, imho, one of the best replies (at a relatively high cost) against notorious London players.

1. d4 c5
2. dxc5 Qa5+
3. White blocks check, Qxc5
What would white do after, and is this a good opening for black or not? Thanks!
Old Benoni is playable, But after dxc5, you don't immediately capture that pawn back by Qa5+ and Qxc5 because that queen will become a target for White's minor pieces, Allows white, easy development and initiative.
the problem with 1..c5 here is that it invites the benoni without actually forcing it. you have to deal with other white setups that don't include d5, and the ones that do at a later stage, while you have already shown your hand way too early. as far as i can tell, you did not cut out white's options but you cut out your own options by playing c5 so soon. if you want to play flexibly and allow almost everything from white, then 1..e6 is a better try as white can't prevent c5 later indefinitely anyway. at least you get white to show his hand for a move before you do.
1. d4 c5
2. dxc5 Qa5+
3. White blocks check, Qxc5
