I have release a small tool to help some engine owner to modify their opening book.
Some engine like Sjeng one, use square notation in his opening book, like e2e3 b7b5 f1b5, but in our opening book or nilatac’s one , we use SAN notation, like 1.e3 b5 Bxb5.
It can be boring to manually translate SAN notation to square notation so I have release a Gui Translator to translate from SAN notation to square notation.
The tool can be use for regular, suicide or Losers chess. It be can download in our download section
