B27 Sicilian: 2.Nf3, unusual Black 2nd moves (1.e4 g6 2.d4 Bg7 3.Nf3 c6 4.c4 d5 5.cxd5 cxd5 6.e5)

This one was played in the second round of the WORLD OPEN RAPID tournament that was held at the FIDE Online Arena on March 17th 2015. After two rounds I had won one and lost one. My opponent did not make as many mistakes as I did, so forgeforever did deserve to win this game. I mean I did not even take the free pawn that was offered to me in the opening, I can't believe I missed 12.Nxd5. Hmmm, maybe I was afraid of 12...e6 and I am actually not sure how to reply to that move even now. I checked the position after typing the previous sentence and it seems if 12...e6, then 13.Bc7 saves White's pieces and the pawn has been won without any problems.
