I played a game in which i pincered in the middle of a black formation and my pincer was surrounded on a bigger scale than I would have liked. I tried to pull the pincer stone (move 2) out with pretty bad results.
The continuation from the game is below. But my question is, if White doesn't pull the stone out, is the result okay?

If White does not like the development after at "b", perhaps he should not invade at . After all, the simple keima at "c" is fine. 
As the game went,
should simply extend on the right side. still has aji.
