Move Order Sicilian Kan

I have been playing the French for a long time. Now I am trying to learn the Sicilian Kan. I was wondering if it's a good idea to use the move order 1. e4 e6 2.d4 c5 (instead of 1. e4 c5 and 2... e6). I was thinking that 1....e6 might help avoiding some closed Sicilians since most White players will continue with 2. d4. Are there any disadvantages?

No, the Franco Benoni (1.e4 e6 2.d4 c5 3.d5!) Is advantage White.

Basically any benoni without c4 by White is better for White than those with c4.

Thank you. Makes sense. There was actually one player who continued 3. d5.

You can do that but you HAVE to enter the french against 2.d4

Well, most players so far have played 3.Nf3 transposing to a Sicilian...

3.d5 gives a bigger advantage to white and i recommend you start with 1.c5 and learn the closed sicilian for black. its typically very easy for black to equalize in and you often get a big center and quicker queenside attack

its just the open sicilian can be difficult to deal with because of your small center and lack of development, which makes you subject to a strong attack. so i recommend you study that the most

One advantage to knowing the Kan is you can avoid some of the trash lines:

At chess.com, everyone and their Grandmother plays 2.Nf3 d5 3.exd5 exd5 4.d4, reaching the Exchange French, which I see as a joke to beat or at minimum draw, others see as an annoyance.

Over the board, 2.Nf3 often for me means wing gambit - 2...d5 3.e5 c5 4.b4.

You COULD, against 2.Nf3, play 2...c5 and against 2.d4 play 2...d5.
