Alan Lasser's Game of the Week

 
 I didn’t know how lucky I was at the Kopec Memorial when I drew a master who made two inaccuracies as time ran down. When we shook hands, he had two minutes left on his clock and I had five. The computer says White has the better endgame, but it wasn’t going to be easy and securing the draw was important to regain my expert title. I needed one game with a rating point upset performance, and there it was. I grabbed the half point he offered, disdaining the chance to play the good knight against the bad bishop(White to move, Kc2, Re4, Re1, Nc4, P-a4,b2,f2,g2,h2. Black Kg8, Rd7, Rd4, Bg7, P-a7,c5,e5,g6,h7). The very next week that same master upset a GM in round one at the 2017 National Open.
