Changes

Dartmouth's most "informed" table was the one on pawn formations, called "PFORM". Among its standard detectors were [[Isolated Pawn|Isolated Pawns]], [[Backward Pawn|Backward Pawns]], [[Doubled Pawn|Doubled Pawns]], [[Passed Pawn|Passed Pawns]], and [[Duo Trio Quart (Bitboards)|Duos]]. Detectors such as [[Pawn chain|Chains]], [[Defended Pawns (Bitboards)|Mini-chains]], [[Backward Pawns (Bitboards)|Shielded Backward Pawns]], [[Candidate Passed Pawn|Potential Passed Pawns]], and the table, "Levers", were among the more esoteric concepts which were added later. Many of these definitions were taken directly from [[Hans Kmoch|Hans Kmoch's]] classic work ''Pawn Power'' <ref>[[Hans Kmoch]] ('''1959, 1990'''). ''Pawn Power in Chess''. New York: Dover, 1990. Previous ed.: New York: McKay, 1959. ISBN 0-486-26486-6, [http://books.google.com/books?id=FT7hpAiec3EC&dq=Pawn+Power+in+Chess&pg=PP1&ots=q_yCx72Ms_&sig=sKrQzXouaweUYbwCjfTcaplUF4U&hl=de&sa=X&oi=book_result&resnum=1&ct=result#PPA1,M1 Google Books], [http://www.amazon.com/Pawn-Power-Chess-Hans-Kmoch/dp/0486264866 amazon]</ref>. The concept, Levers, using a modified definition of my own "pawn mover wich improve our formation and hurt our opponent's" - proved useful in the recognition of critical pawn moves. In addition, the levers concept helps to guide the placement of pieces especially in the opening and middle game. It could also help toward plan formation. Some further pawn formational concepts from ''Pawn Power'' which were never programmed were [[Outposts|Outpost]] and [[Holes|Weak Square]] Complexes. The Dartmouth program is probably, in theory, capable of more sophisticated pawn formational evaluations than any other program; however the implementation is rudimentary. The program had at one time approximately 50 detectors in various tables and many others were planned.
