After 1.e4 c5 2.b3 Black has at least three important defences:
A) the d6/e5 setup mentioned in Martin's article.
B) 2...d6 3.Bb2 Nf6 omitting e7-e5.
C) 2...e6 and probably best is 3.Nf3 (3.Bb2 b6!), transposing to the Westerinen Variation or Finnish Attack. We can start discussing names again.
The reason sources are not discussed, is that they do not exist. So Basqueknight, why don't you come up with a specific line? If you want to play this, you will have to do a lot of work on your own.
I was not really convinced by Martin's article on A. In one of the two games White played Nf3-g5 followed by f2-f4, but Black could have prevented this by an early h7-h6 and then what?
The important question for White is when to play f2-f4.
On C you should consult other threads.
On B I don't really have a clue.
