{Brief theoretical reminder (this will help to better understand the black
defenses on the bad White moves): pawns spaced in this way win very generally
when they are two Bishop pawns because there is enough space outside for a
passage of the K. In the present case, the rule is rather at the draw, the
black K blocking the "d" pawn and the B blocking the "g" pawn, this pawn being
sufficiently close to the edge to not allow the White K to bypass. This study
is obviously not an exception, but illustrates a case of win when the Black
King is not yet in place ... and the Black Bishop very poorly placed to take
the role that is usually his.} 1. Ke5+ $1 (1. Kf4+ $2 Kf7 $1 2. Ke5 (2. g5 Ba5

{[#] This study is a correction of a very beautiful Halberstadt study of 1936.
In the original study, the White King is on h1 and Black Rook on e2. The win
after 1: d7 Rd2 is well based on a single win maneuver of 4 moves, but the
order of the moves can be reversed (concretely, Kg1 must be played but can be
at any time). This remarkable study is perfectly commented on by A Pallier in
the special issue of Phenix 278 P 10946 and I encourage the reader to refer to
it. V Samilo eliminates these duals by a small modification and thus
rehabilitates the study of Halberstadt in the eyes of those who do not accept
the duals.} 1. d7 (1. Rb8 $2 Rf7 $1 $11 ({and not} 1... Rd2 $2 2. Rd8 Kb4 3. d7
