Position after 135... Kd3
[D] 4K3/8/5r1p/4QPbP/1p6/3k4/P7/8 w - - 0 135
In this position I didn't get any good defense for black if white takes
the "b" pawn. For example, after 136. Qc5 {!} Ke4 137. Qxb4+, I think
that white wins due to strong "a" pawn.
If blacks try to defend "b" pawn, white wins.
136. Qc5 {!} Bd2 {? (Only way to defend "b" pawn)} 137. Ke7 {!} 137... Bc3
