Sd: a checker-moving program that is powerful, sophisticated, accurate and reliable.

The current version of Sd/Sdtty is 37.6, released on March 30, 2008.

This version supports the "mimic" concept.

There is a new "Frequently Asked Questions" (FAQ) file. See the link below.

Sd and Sdtty are now distributed under the GNU General Public License. Source files are available below.

Hints for inexperienced users:

(1) You may find that Sd is more user-friendly than Sdtty, particularly if you are having trouble with sessions or abridgement files. It will show you the startup options more clearly. You can type commands at Sd the same way you type at Sdtty. It just looks different.

(2) If in doubt about how to enter some complex call, type part of the call and a question mark. For example, if you want to know how to modify the star turn on a chain reaction, type "chain reac?". Then, following its hint, type "tion, turn the star 1/2".

(3) You may have heard that Sd lets you type complex calls directly, using brackets, as in "catch [motivate] 3". This is true, but you may find it unwieldy if you are accustomed to entering things piecemeal. You can still do it that way. Remember to type "<anything>", not just "<any>". For example, type "catch <anything> 3". (Not sure about that? Type "catch" and a question mark.) Then type the "motivate".
