[FEN ""] [StartPly "5"] 1.e4 c5 2.Nf3 Nc6 3.Bb5
In this opening is it better to do e6 to activate the dark square bishop which will protect c5 pawn. If the opponent plays Bxc6, it will have a double pawn in the c file but the dark squared bishop might help the pawn on c5 or g6 because I think the Bishop will be much better on the long diagonal. Also keeping open the option to recapture on c6 with the d-pawn to open the Queen and light squared Bishop. Also not worried about them doubling the pawns because of the Bishop pair to compensate.
I gave my explanation for both moves but which move do you think is Better?
