Game of the Week, by Alan Lasser

     My sleazy attempt at a trap 16.Be3, hoping for 16…Qf3 17.Ba7 Ka7 18.Qf3 was duly punished by my opponent’s rook sacrifice in this exciting game between ex-experts at the Norwich Chess Club.
     He didn’t find the best continuation at game/15, nor did I find the best defense, so the eventual perpetual check seemed like a fair result.
