> Here the black pawns might actually help shield the white K That is most definitely the case. If Black did not have the pawns on b7 and d6 the World could swiftly force a variety of draws. An example is the so-called Endgame G: 47. Kf5 Nh8 48. g6 d2 49. g7 d1Q 50. Rxd1 Kxd1 51. gxh8Q b1Q 7Q/1p4P/3p4/5K2/8/8/8/1q1k4 w If the Black pawns were absent, we would have 7Q/7P/8/5K2/8/8/8/1q1k4 w which is a tablebased draw. However, all the current analysis by the World Team suggests that with the two pawns on Endgame G is almost certainly lost for Black. The current main line is 52. Ke6 Qe4+ 53. Kd7 Qa4+ 54. Kc7 d5 55. Qg7! Qc6+ 56. Kd8 Qb6+ 57. Kc8! Qc6+ 58. Qc7! Qf6 59. Qd7! Qh8+ 60. Kxb7 Qb2+ 61. Kc6 Qh8 62. Qxd5 and we're back in the tablebase, but this time it's a win for White... 47. ... b1Q takes us to a ending with an advanced White g-pawn rather than h-pawn, which currently seems to offer much better drawing chances, but again it would be much easier if neither Black pawn was on the board! (c: 7Q/1p6/3p2K1/6P1/8/8/8/1k1q4 w For those interested...
