Catalan

Last year I've almost switched from e4 to d4 and I'd like to try the Catalan as a way to avoid some important defenses for black. A good choice for a low rated player as me, or perhaps too much subtle? It seems like black could take the c-pawn and keep it hold without too very much risk, unlike it happens in QGA. Maybe I should try first 5. Qa4+ instead of the main variations?

Thanks in advance.

The Catalan does require immense finesse.

But I have fun with it.

Thanks, Morpheus.

I've played the Catalan--both sides--as a strong class player. I must second IM Pfren's assertion with slight reservations. The Catalan is mostly over the head of those under 2200. I still play it, but it often brings suffering.
