What is this nameless gambit??

Hi, I was bored, so I looked for some strange variant in the Sicilian Defense, particularly in the Katalimov variant. The gambit is: 1.e4 c5 2.Nf3 b6 (Katalimov variation) 3.d4 Bb7 !? 4.dxc5 Bxe4! .
the situation is even, and in certain lines black is ahead. of course, the Katalimov variant is not very played, but I am surprised that this gambit / variant has no name.
interesting is the line: 2... b6 , 3.d4 Bb7 4.dxc5 Nf6 5.bxa7 Qa5+ 7.Nc3 Nc6

call it cookie gambit lmao (i don't really know what to say)

Why should white even consider taking on c5? Why not Nc3?

After dxc5 isn't there the B pawn to take...

How can bxa7 happen after dxc5

1. e4 c5 2. Nf3 b6 { B27 Sicilian Defense: Katalimov Variation } 3. d4 Bb7 4. dxc5 Nf6 *

5.bxa7 Qa5+ 7.Nc3 Nc6 does not compute
(there's 6. missing too)

4 d5 should be good: Bb7 bites on granite.
When something has no name it often is no good.
The whole point of any Sicilian is to capture 3...cxd4

it's simular to Cormorant Gambit
useless opening

Agree with @tpr, simply 4.d5 and black has a bad Benoni with a useless bish on b7.

Bb7 will naturally resolve to F.
