Lev Polugaevsky was a great player, worthy of commemorating with a chess tournament or two, but alas: both in the recent event won by Dvoirys and in the famous Buenos Aires tournament in 1994, held a year or so before his death, none of the players saw fit to honor him by playing his signature variation. The Polugaevsky Variation (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6 7.f4 b5!?) is quite risky, of course, but it would be a fine tribute. (A suggestion to players, in case there are any subsequent Polugaevsky Memorial events: if Black is in sufficiently bad shape in the main line, perhaps the players could agree in advance to simply avoid the main line.)
