Just played first game since starting the course ( 1/2 way through 4 , first time ) . Was in a 24 hour 3 min blitz arena ( World Chess Day ) on Chess.com . 3 mins is a little quick for me , but although I lost on time against an opponent rated 275 above me 1133 to my 858 , according to Stockfish outplayed them !! This course must be helping me greatly – was far more on the look out for tactics etc . Played the Colle ( thanks Nelson ) not Stonewall though !
