nice trap thnx

well done!

Perhaps you could have made it a little more obvious that it is black to move?

Nice trap though, wouldn't 15.Qd1 have been better for white?

It's first time when I post a game ( a part of my game).

My strategy was improving queen position and leting  a poison pawn at d5.

You dont think having a caption saying 'black to move' is enough?

Thanks for your comments. Next time I will chose some words that say more.

12...Qb6 drops a pawn because 13. Bxd5 Nxd5 14. Nxd5 and now Bxb2 isn't a good option because after 14...Bxb2 15. Nxb6 Bxc1 16. Nxa8 Bxd2 17. Nc7, the smoke clears and white is up the exchange. 

13. Nxd5? was a mistake by your opponent. 

I didnt say somthing else ... but taking a pawn and threateaning the queen was a nice trap.
