On a wing (gambit) and a prayer

Some Sicilian wing gambit disasters for both sides:

Truly dreadful, brought a knowing smile to my face.

I'm a bit confused on the Kujuth game why White didn't play 7.exf6

7.. Qe5+!

Since after 2.b4 cb I play only 3.Nf3, there might be also something interesting here :) Can anyone tell about some good ways for Black after 1.e4 c5 2.b4 cb 3.Nf3 Nc6 4.d4 d5 5.ed Qxd5 6.c4 ?

What about the Sicilian wing gambit's evil twin, the Krejcik Gambit:  1.d4 f5 2.g4!?  It's actually not that bad. Check it out in the DBs.
