Hello! My name is Aleksey Goganov, Im GM from Russia. I quallified 2 times in World Cup, 2 times in Russian Superfinal ( round robin tournament with most of Russian topGMs, average Elo is about 2700, best result 5.5/11), my peak Elo is 2643, current 2597. Till now i continue my carreer and hope that there will be new achievements in future.
Also I'm a chess coach. I have huge knowledges in openings, especcially with black because on different stages of my carreer i played practically everything. I can also help you to improve endgame and middlegame understanding mostly by studing typical ideas both positional and tactical. If you are still not a GM i think its the best way to improve your play.
And I open for tournament invitations of course).
