What is this opening called?


This is a sicilian defense, it may still become one of several popular variants of the sicilian but I am not familiar with a sicilian french variant.

It's actually a different move order of the Sicilian Kan variation or a different move order of the French variation.
This is usually seeked by black for a calmer game than usual, because games with 1...c5 are usually very sharp (it is not a poor opening for black, it is the most common response to 1.e4. I don't know much about the french variation, however.)

It's a different move order of the Sicilian with 2... e6:
1. e4 c5 2. Nf3 e6 3.d4
It would probably be better for Black to play 1. e4 c5 2. d4 cxd4, which would be the Smith-Morra Gambit.
