equalize with either 8...Nfd7 or the rarer 8...dxe5 9.fxe5 Nfd7. By far the most popular continuation for White is 8.Bb5+, the Taimanov Attack. Analyzed by Mark Taimanov in 1956, the strength of this variation was not fully appreciated until the early 1980s. The point of the check is that both 8...Bd7 and 8...Nbd7 allow 9.e5 with advantage to White, since the knight on f6 can no longer retreat to d7. After the strongest move 8...Nfd7 the most popular move used to be 9.Bd3, preparing to meet 9...a6 with 10.a4. But in two crushing and high-profile victories with White (against Frans Andre Cuijpers at the 1980 World Junior Chess Championship in Dortmund, and against Nunn at the 1982 Olympiad in Lucerne) Kasparov showed that 9.a4 was more dangerous for Black, it having the advantage of not determining the bishop's retreat square for the time being. White's success with this idea led some to question the soundness of the Modern Benoni, at least in its original move order. In 1982, Nunn concluded his analysis of the Taimanov with the words, "Black badly needs a new idea against 8.Bb5+ and 9.a4 to keep the Benoni in business"; two years later, he had given up the opening altogether. Other players such as Psakhis resorted to using the move order 1.d4 Nf6 2.c4 e6, only playing 3...c5 in response to 3.Nf3 to avoid the Taimanov, while choosing an entirely different opening against 3.Nc3. The damage this variation did to the opening's reputation led David Norwood to rechristen it the "Flick-Knife Attack." Not until the 21st century did players and analysts begin to revive Black's chances in this line. First, Watson showed that the disruptive check 9...Qh4+ was playable, the point being that after 10.g3 White is no longer able to bring the bishop on c1 to the squares g3 or h4, where it can assist in White's kingside attack. Later players such as Gashimov showed that the queen check is not mandatory, and that Black also retains good chances in the line 9...0-0 10.Nf3 Na6 11.0-0 Nb4, taking advantage of the outpost on b4. 7.Bd3: Knaak Variation The move 7.Bd3 is sometimes used by White to enter the Modern Main Line after 7...Bg7 8.h3 without allowing Black's attempts to play an early ...Bg4. It is also the prelude to a variation championed by Rainer Knaak, 7...Bg7 8.Nge2 0-0 9.0-0. White's plan is to play for
