Other results seem quite normal with a few exceptions (ProDeo could be a bit higher and Tao lower in the list). But since Fruit 2.1 has been released, never did Fruit (2.1, wccc or 2.2) achieve such a disappointing result in any official public appearance. At WCCC Fruit had finished 2nd with 77.3% against a stronger field. At CCTblitz Fruit finished equal first with 83.3%. Even playing with a non-tuned book, Fruit is presently leading the field at WBEC riederkerk with 68.3 %. Here Fruit has a miserable 58.3%¨performance so far and it has lost as many half-points in 6 games than in the whole stronger 11-games event in Reijkjavik. OK Fruit has already played (and lost) against the two strongest opponents but it still has to meet The King, Ktulu, Deep Sjeng and/or Gandalf. If Fruit cannot manage to win its three remaining games this tournament will be a real black stone in Fruit's garden. At the opposite, Zappa's comeback is a near-perfect demonstration. 2. After 48 games, Black has won more games than White with a stunning figure : W:+17 B:+21 and 10 draws. IMHO this could illustrate the fact that opening books are much more tuned for the black side than for the white one. Every book cooker knows that a performing black repertoire is critical. When I cooked the book for fruit I was so convinced of that that I once had to stop tuning the black repertoire (a few days before CCCblitz) to take emergency measures for the white side : Fruit was beginning to get much better results with black than with white in my private tests. 3. Zappa-Fruit is a well-deserved win for Zappa. Fruit went on in a difficult defensive position. At move 12, Fruit opted for the passive 12...e6 although 12...Qb6 has had better practical results in human master games recently. [D] r2q1rk1/1p1n1ppp/2p1p1b1/p7/Pb1PP3/2N1BP2/1P2B1PP/R2Q1RK1 w Here Zappa's 15.Rc1 was a good new move after which Fruit's 15...Qc7 goes directly into problems on the c file. After that 16...Rad8 was mandatory to avoid d5 but fruit played another dubious move (16...Rfe8) and Zappa did not miss the opportunity to take a clear positional and soon material advantage with 17.d5! I do not know where was the end of Fruit's prepared book line in this game but it clearly led to a difficult position where fruit was not able to find its way. 4. Fruit-Diep is another example of questionable book choice. I have had dozens of private games where Fruit did not find the good balance between timed agression on the king-side and necessary defensive measures on the queen side in such opposite-castling sicilian positions. I think it is extremely dangerous to venture with fruit in such positions against first-class opponents. The game was known theory for long. [D] r2q1rk1/3nbppp/p2p4/3Pp1P1/1p6/1N1QBP2/PPP4P/2KR2R1 b Here, after 16...a5 Fruit went for 17 Nd2 whereas most recent games saw 17.Kb1 chosen by white with much better results. Then Diep played 17... a4!? instead of the well-known 17...f5 and immediately fruit played inappropriately 18.Ne4?! after which 18...Qc7 19.h4 b3! led to an irresistible black attack. 5. Against Xinix Fruit got a draw in a drawish opening that it had itself chosen as white. 6. But Fruit has also already had good games with good opening preparation. Against ProDeo Fruit went for an early highly speculative exchange sacrifice: [D] r1bq1rk1/ppp3bp/2np2p1/1B2pp1n/4P3/2PP1N2/PP3PPP/R1BQRNK1 w Here the play continued with 10.Bg5 Bf6 11.Bh6 after which Fruit's strange 11... fxe4 12.Bxf8 exf3 13.Bh6 fxg2 14.Ne3 Ne7 led to a difficult to evaluate position where Fruit prettily outplayed its opponent. If this was prepared, then this was genial opening prep perfectly tailored to Fruit's qualities. Marc Lacrosse
