I mean you do you man, but getting that pawn back in Catalan is much harder than Queens Gambit. And I am not sure if you nor I could prove the compensation white has for the pawn.
But why should we stop you if you are enjoying it and see results for it though?
Playing the true gambit line isn’t abnormal, even b3 can be further offered for piece activity. Learning to play with the initiative can be fun and rewarding.
To the OP, you can play the Catalan thru 1.Nf3 move order if you want to side step the theory and opening tricks.
I am essentially a 1.d4 player with the white pieces and I have been trying out the Queen's Gambit. Usually in case of QGD I try to develop naturally and enter a favorable endgame. However in some of my recent games, I transposed from the Queen's Gambit to a Catalan-esque opening. This gave me positive results, however I am vexed by the fact that the Catalan is supposed to be one of the most complex opening in theoretical terms and thus a person of my rating should generally avoid it. Should I keep trying the Catalan in my games or stick to the standard Queen's Gambit lines?
