The Random Game feature at chessgames.com is a handy way to broaden your chess education. You never know what's going to pop up. You may see a famous classic, or maybe a subtle modernity, or maybe a true obscurity. You might even find a diamond in the rough that nobody else has spotted. This game from two players who are less well known (Anatoly Lutikov and Mamadzhan Mukhitdinov) features the equally less well known Queen's Gambit Accepted, Showalter Variation, though it might also be classified as a Grunfeld. Look for references to Showalter's games in the score. You can also try the random game idea yourself here.
