I would've played g2 instead.  g4 loses to c5.

I thought of c5 because I used to play it more often against c1, and I learned that to get a height-3 escape from it, one connects it _away_ from the edge rather than _towards_ the edge.]

B5 was certainly _worse_ than C5, but I'm not so sure C5 was winning, since White can get a height-2 ladder.]
