13.......d5 looks forced and Black hopes to mobilize via ......Bd7 and ....O-O-O. It's up to White to prevent that defense -- as you are ahead several tempi.
once you won the piece with Rxc6, Black had no counterplay, ie; on 17.....d6 18 Qxg7 wins
please don't feel bad on missing quicker wins. The main thing is once you find a forced, winning line that is sufficient. Sure, you can improve your winning technique when having a similar future position. But how you won, was decisive. no one can argue with that ! well done !!
I'm not a high rated chess player, probably around 1500 or so, but I enjoy the game so much. I've just played what I consider to be one of the games I've played.
I sacrifice 3 pawns for a strong initiative, which I managed to convert into a victory. What do you think of it? I'm sure I made a lot of mistakes, but that's normal given my rating and the time control (5|0).
I hope you enjoy, and I'm hoping stronger players will give me some friendly advice on the game and annotations I've made.
Thank you for your time.
