I think there&#x27;s a typo in HAKMEM: item 70 is a chess problem purportedly stolen from Lasker&#x27;s <i>Chess for Fun, Chess for Blood</i>.  As far as I can tell, it is problem 66 from Lasker&#x27;s book, on page 145 [1].  However, there&#x27;s a crucial mistake: the white bishop is supposed to be on QB8 (f8), not QB7 (f7).  HAKMEM&#x27;s version [3] is still a mate in 3 like advertised, but the original problem as Lasker has it [2] is <i>much</i> more interesting.<p>[1] You can see it on Google Books <a href="https:&#x2F;&#x2F;books.google.ca&#x2F;books?id=y90UTQeLeeIC&amp;pg=PA145" rel="nofollow">https:&#x2F;&#x2F;books.google.ca&#x2F;books?id=y90UTQeLeeIC&amp;pg=PA145</a><p>[2] FEN for Lasker&#x27;s version: 5B2&#x2F;6P1&#x2F;1p6&#x2F;8&#x2F;1N6&#x2F;kP6&#x2F;2K5&#x2F;8 w - - 1 1<p>[3] FEN for HAKMEM&#x27;s version: 8&#x2F;5BP1&#x2F;1p6&#x2F;8&#x2F;1N6&#x2F;kP6&#x2F;2K5&#x2F;8 w - - 1 1
