for the reasons stated by davidt722, i think e6 is the best defense from the QG.

defending the pawn with a move like e6 still alows black to develop a bit more with tempo, not wasting time or material bieng chased around the board. it also strengthens its dark bishop by creating an open diagonal.

i agree with defending the pawn instead of taking as well, almaster. the question is with what piece you defend it, in my opinion.

p.s.- sorry it took me so long to reply. i have been on vacation.

I think the black should defend the pon rather than taking it because then the black will lose the center and that is bad. Right?

sorry for the typo in the title.
