For this reason I firmly believe that > Fruit's 17...Bd7 is fine here and most probably > the best winning try. The best defense is interesting! After 17...Rxc3?! 18.fxe6 Ra3 then 19.bxa3 is the only good defense but this is easy. Then after 19...Qb6+ white should avoid 20.Kc2? that is losing by force...... And play 20.Bb5! that saves the game. This is a good/hard testposition for computers as it isn't easy to see....... After 20.Kc2? we have the forced moves for white: 20...Rc8+ 21.Kd2 Qxd4+ 22.Ke1 Qe3+ 23.Be2 Bc3+ 24.Kf1 fxe6 25.Qg4 (25.Bf3 Rf8 -+) Rf8+ 26.Bf3 Ba5! 27.Qg3 (27.Rb1 e5! -+) Bb6 28.whatever e5! -+ -+ means an endgame with a Queen against 2 Rooks ans 1-2 Pawns more. Not very easy after all but advantage for sure........ So white to play and avoid Kc2? and play Bb5! [D]5rk1/pp3pp1/1q2Pb1p/3p3Q/3P4/P7/P5PP/1K1R1B1R w - - 0 20
