Only in chess does it make more sense to talk about a “Sicilian Dragon” than a “Chinese Dragon.”

The Sicilian species is characterized by the moves . . . c5, . . . d6 and . . . g6, and gets its name from a pawn structure that looks like the constellation Draco (The Dragon).

It’s a well-known opening that typically comes about via the moves of this week’s game. Black usually continues 10 . . . Rc8 so that the rook controls a half-open file and prepares . . . Ne5-c4.

Until a few years ago, there was no such thing as a Chinese Dragon. But a variation of the Sicilian Dragon, characterized by 10 . . . Rb8, to support . . . b5-b4, is catching on. Although it was played 30 years ago by a Dutch amateur, it get its name because of its adoption by Chinese players such as Bu Xiangzhi of Qingdao.

Gabor Papp of Hungary, who was Black in this week’s game, had played 14 Nd5 once when he was White and was rewarded by 14 . . . e5? 15 Nf5!.

America’s Ray Robson, who turns 15 next week, improved on another previous game with 16 h4!, rather than 16 Nxf6+. Black missed good opportunities for . . .Bxb3 and allowed a killing sacrifice, 28 Rxh6!.
