By the way, asmFish preferred 38. Nxa4, which it evaluated as 0.00. Haven't studied the line, but here it is in case anyone is interested:

Code: Select all

0.00 38. Nxa4 Qxa4 39. Qb2 Rgh8 40. Bg3 Qa5 41. Rb1 Nc6 42. Kg1 Kb7 43. Kf2 Rb8 44. Ke3 a6 45. Rg2 Nb5 46. Bf2 Rd8 47. Rbg1 Rd7 48. Rg5 Ne7 49. Kd2 Qxa3 50. Qxa3 Nxa3 51. h5 gxh5 52. Bh4 Nc6 53. Rg7 Rxg7 54. Rxg7+ Kc8 55. Rg8+ Kc7 56. Rg7+ Kc8 (depth 62, 4:34:31)

I am not interested in quick draws, when I know white has substantial advantage: at least 30-40cps.

and this has been true all the way.

SF is showing black edge, because it does not have eval for a couple of important pawn features, like black g6 twice backward feature above, bad psqt for defended pawns, the white central defended pawns are much weightier asset than what SF thinks, etc.

so, score is in white's favour, no matter what SF thinks.

it is a pity I have to take a vital decision, when I am tired late in the knight.

but that is chess...

Louis, that might be my last move for today, if you play very fast, I might do one more, but no rush, please take a careful analysis, tomorrow we will continue.
