That game, which saw Black embark on a very sharp sacrificial path, continued 9.Ng3 Bg4 10.f3 e4 11.cxd4 Bd6 12.Bxb5+ Kd8 13.O-O exf3. IM / GMC Estrin later published, in 1971, the suggestion 14.Qb3!? as an improvement on the game continuation, and this possibility has continued to interest many players.
