Chess Tactic puzzle

In this blitz chess opening I missed a great tactic opportunity. Can you guess what move it was on move 12?

Solution

You will find out if you watch the end of this movie.

  1. d4 Nf6 { A45 Indian Game } 2. e3 g6 3. Bd3 Bg7 4. c3 d6 5. Ne2 b6 6. O-O Bb7 7. f3 O-O 8. e4 e5 9. d5 c6 10. c4 cxd5 11. cxd5 Nbd7 12. b4 Ne8 13. Bb2 a5 14. a3 Rc8 15. Nd2 Qg5 16. Nb3 a4 17. Bc1 Qe7 18. Nd2 Ra8 19. Bb5 f5 20. Bxa4 Nef6 21. exf5 gxf5 22. Nc3 e4 23. fxe4 fxe4 24. Bb2 Bxd5 25. Nxd5 Nxd5 26. Bb3 Nf6 27. Rc1 Kh8 28. Nc4 e3 29. Bxf6 Rxf6 30. Rxf6 Qxf6 31. Qxd5 Qf2+ 32. Kh1 Rf8 33. Qxd6 e2 34. h3 e1=Q+ 35. Rxe1 Qxe1+ 36. Kh2 Qf2 37. Qg3 Qf6 38. Nd6 Qe7 39. h4 Be5 { White forfeits on time } 0-1
Sort:  

12.. Bxd5! 13 exd5 e4 14 Bxg7 exd3 15 Qxd3 Kxg7
On 14 Lxe4,14.. Lxb2 follows and the rook in the corner is trapped.
After 14..exd3, if 15 Lxf8, 15 dxe2 follows, the queen is threatened, and white has to recapture, leaving black a pawn up, with two pieces for the rook,effectively two pawns up.
It took me a while to see it.

Good job. :)
After his pawn b4 move I hesitated a little because I was kind of surprised by this move but I could not find the correct reply to this weakening move. And in a blitz game you always have the ticking clock at your back.

Or (12... Nxd5 13. exd5 e4 14. fxe4 Bxa1 15. Nbc3 Bxc3 16. Nxc3 Qe7 17. Bf4 Ne5 18. Qd2 f6 19. Bg3)

And btw, it would be cool to play a match later.
Or a stream even. I´m now using the same nick on Lichess, Kooshikoo.

I'll be on lichess in about 3 hours. Streaming is a little problem since my dsl connection is sort of slow and in blitz games I need a good ping time. But recording and uploading the match later works, too. :)
