I play the Catalan with white.
The catalan is a kind of opening that gives white a small pull in pratically any setup. Although this pull is probably smaller than other white d4 opening setups it is also harder to neutralize. It is normal seeing white keep a small pull till far in the middlegame and even endgame.
In other words there are no variations that force a draw of quick equality against the Catalan.
This is kind of logical else why would all the strong players play it.
I'm searching for a simple line against the Catalan opening. The closed def. is too heavy against stronger players and 3...c5 is not for my taste.
I have thought about 5...Bb4+ and playing something else than 6...a5 which is the move that GMs prefer. Please post if you have experience in this opening
