Zeitung</em> (run by Harald Keilhack) has published a set of
retro chess puzzles. </p>
<p><span>In the sign of the retracting
a move</span>, this year's Christmas puzzles are presented, as
always, compiled by Werner Keym.<br>
By retracting a move, chess men that have already been captured
can come back to life, and if necessary, a (pawn's) promotion can
be reversed.<br>
As usual, it should always be checked whether there are multiple
solutions. </p></div><br><div dir="ltr"><br></div><div dir="ltr">Puzzle 1:<br></div><div dir="ltr"><br></div><div dir="ltr">Bernd Schwarzkopf<br></div><div dir="ltr"><br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">|? ?|? ?|? ?|? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">|? ?|? ?|? ?|? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">|? ?|? ?|? ?|? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">|? ?|? ?|? ?|? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">|? ?|? ?|? ?|? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">| P |? ?| k |? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">| P |? ?|? ?|? ?|? ?|? ?|? ?|? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr">| R |? ?|? ?|? ?|? ?| R | K |? ?|<br></div><div dir="ltr">+---+---+---+---+---+---+---+---+<br></div><div dir="ltr"><br></div><div dir="ltr">[8/8/8/8/8/P1k5/P7/R4RK1]<br></div><div dir="ltr"><br></div><div dir="ltr">White retracts a move and checkmates in three moves instead.
