Rxa7 Qh3 36. Bb6 Rxa7 37. Bxa7 Bc3 38. Rb1 Re8 39. d6 Re2 40. Qxe2 fxe2 41. d7 Bf6 42. Bb6 Kf7 43. d8Q Bxd8 44. Rf1 -2.69 35. Bxa7 Rxa7 36. Rxa7 Bd4+ 37. Kh1 Bxa7 38. d6 Qf7 39. Qd2 f4 40. Qxf4 Qxf4 41. gxf4 Rxd6 42. a5 -2.68 Also interesting: 35. d6 Qh3 36. Bc5 f4 37. gxf4 f2+ 38. Bxf2 g3 39. Bxg3 Rf7 -2.32 But with d6 found DS now a better Variation. At the moment (after 286:59) is the move 35. Qc4 with +0.53 (for DS). Best Frank
