I think I played very well this game. I felt like all my moves were strong and this was a fun game to play.

in the variation you mention 18.Qd2 Qxf3 19.Qg5 you can play 19..Bxf2+ and after the capture with the rook you play 20..Rd1+ 21.Rf1 Rxf1+ 22.Bxf1 Qxf1#. The sacrifice Nf3+ was good, maybe someone better or with more time to look at it will find a defence.

The game was indeed very good and your moves very strong and accurate.The sacrifice was also very good and ended very nicely an already very nice game.Well done!!!
