king's gambit, uhhhg

so I've studied lots of king's gambit variations.  I thought I was pretty well versed (even after I played a strong opponent in a tournament in the declined and fought back and forth for equality, Roy H). 

black can try to save the pawn and could face a king attack or at least lack of center control, give the pawn back, or even FalkBeer countergambit

well, after lots of practice, the easy level on my computer hit me with bishop d7.  Can anybody let me know what to do here?

the pawn is accepted, white plays N e3, then damn he plays B d7, very simple but with all my stuff I can just break even.  Any tips, I'd appreciate it

You mean Be7 and Nf3?

sorry, yes Be7 was the computer's move, I'm white
