Here's my recent game against an opponent rated 200 points higher than me. We both made some mistakes but overall it was a very interesting and entertaining duel. Enjoy and comment!

White's play was very poor. 5g3 with e3 doesn't look good. 6b3?  seems to make black's normal c5 stronger, to follow up with Qa5, and use bg7.10 ...e6xd5 looks sounder. Don't really see the point of 16...Ba8. 18...c4? white seems to be winning after 19Bxb6. Maybe you intended 19...Bxc3 20Qxc3 pxb3 but this looks losing after 21 RxQ? You left your queen opposite opponents rook for a very long time in fact. Very risky! to put in midly. I will leave it at that, because I don't think people want to be objective with their showcase games really.
