None agreed with DB. In 1997. I think DB was definitely right. I think the best white can get after Rc6 is a draw, when Rc7 wins. Here is some analysis of Rc6: >1. Rc6 Rg5 2. Qe4 (but not Qc4 ? or Rc8+ ?) Qf4 [Amir] 2. ...Qe5 is better for black here. After 3. Qxe5, black can give some problems with the d-pawn and attacking the white king. 3. ...Rxe5 4. Rf6 Re1+ 5. Kh2 Kg7 6. Rf5 Nxf2 7. Rxf3 d3 8. Rxf2 Re2 9. Kg2 d2 10. Rxe2 d1=Q 11. Re3 Qd5+ 12. Kf2 Qxb7 I think black will win here, but it is more difficult than the other lines. If 3. Qxf3, black also gets an attack on the white king. - 3. ...Nxf2 4. Qxf2 Rxg3+ 5. Kf1 Rxh3. And now, 6. Qf6+ Qxf6 7. Rxf6 Rxb3 8. <some move> Rxa3, and now black has all the chances, because white must capture all the black pawns just to get a drawn KRNKR ending. 6. Rc8 Kg7, and now 7. Qg2+?! Rg3 8. Qf2 Rxb3. Now what? White goes down.
