The following blitz game at ICC illustrates a common fork tactic that comes up in the Benko Gambit accepted chess opening. White has an extra pawn, but Black invariably gets tremendous pressure on his queenside even in queenless middlegames!
I believe it was DeFirmian commenting in MCO suggesting that White should forget he is a “pawn up” and play it like a Benoni. The Benko gambit was called the Benoni Gambit before the American Pal Benko popularized it in the United States which led to the name change. It is sometimes called the Volga Gambit named after the Russian river. One chess writer glibly stated that is was a shame such a beautiful opening ceded its name to a mere mortal! Understandable sentiment as the Volga is the longest river in Europe.
BTW, a recurring tactic in the Benko Gambit is illustrated in the diagrammed chess position. Black has two knights in “fork range” of White’s King if White blunders with f4 hanging the e3 bishop. Moreover the c2 Queen and d1 Rook are forkable which makes for a f…ing, I mean forking good time for Black! I have fallen for this tactic more times than I want to admit at ICC.
