In round two of the World Open, still in progress at the Sheraton Philadelphia City Center, international master Dean Ippolito won quickly against FIDE master Boris Reichstein in the classical variation of the Nimzo-Indian Defense.
Reichstein's 15...Bb7 may have been intended as an improvement on a game between Evgeny Levin and Valery Zhidkov from last year's Petrovskaya Ladya tournament in Peterhof (Russia). That game continued 15...Nb7 16.Nh3 Ke7 17.Bc3 d6 18.e5 dxe5 19.Bxe5 Rhd8 20.Be2 Ne8 21.Nf4 Nc5 with advantage to White, who triumphed in 50 moves.
