Veni, Vidi, Vici . . .Sort of

I tied for first place in the U1800 section of the 2018 Westfield Chess Club Championship, and I took home the trophy on tie breaks. Two wins, two draws. Of course it wasn’t that simple. I was dead lost in round four but stubbornly held on until my opponent let me back in the game. As usual, none of my illusions about the quality of my chess survive the first contact with the computer. But this game from round 2 isn’t too bad

2018 New Jersey Open

Three wins, two draws, no losses (I had to skip the 6th round). A surprisingly successful event! I ended up winning the top senior prize in the under 1800 group. But unless you're a strong master, there's always a letdown when you subject the games to scrutiny. Remember the way those pebbles from the sea shore, the ones that gleamed like precious gems when you picked them up on the beach, turn out just to be a bunch of dull little stones when you get them home? My games also lose a lot of their luster when I examine them more closely. This second round game isn't too bad. My young opponent shrugged off this defeat and racked up a draw and three straight wins to tie for second in his class with 4.5 points.
