I wanted to bring my rook to e2, so I first looked at the Bh5 - Bg6 manoeuvre to exchange the white bishop on d3. I realised this plan was too slow and suddenly noticed that I could bring my rook to e2 directly ! I spent a lot of time calculation all the variations, the final conclusion : white will lose a piece.
So I played Re2. My opponent gave me a strange look, had a long think, and finally played Qf1. I played Rxd2, my opponent immediately answered with Bc1 (he looked at me like "you made a big mistake, I'm winning your rook"). My heart stopped beating for a few seconds (his bishop pins my rook on my queen, I missed this move in my calculations). After a few seconds I realised his move was not as dangerous as it looked, I just had to exchange the rooks and move my queen away. So I did, I played Rxd1, he played Qxd1, I moved my queen to f6, and I was a piece up... .
