A very useful way to use the following collections of training positions
is CBLight's "random training" feature: right-click in the database window
upon the database containing the test-positions, then select "properties",
then mark "random traininig" in the window appearing. When starting the database,
you will get a random position presented from the collection. If the collection
already contains the solution moves (like the collection "Bestmove" of U.
Haug), select the "Training" notation display (in the Notation pulldown list
of CBLight Status - Options - submenu).
In some of the collections the positions can be selected according to difficulty (via "themes" key) resp.
tactical theme (via "tactics" key).
- win_trap.zip Winning Chess Traps by Irving Chernev. Thanks to chessguy "Leopold"! (11/Jan/2005)
- mytestpgn.zip Iolo Jones presents some collections of test-positions in PGN Format. Thanks! (03/Nov/2003)
- lctii.zip The Louget II Test allows to calculate the strength of different
chess engines according to their ability to solve 35 positional, tactical and end game positions within 10 minutes. Tauno Leinonen has compared Fritz5.32, Junior5, Crafty, Nimzo99, Hiarcs 7.32 for every position. (19/Nov/1999)
- qmoves.zip Updated! +300 positions with quiet moves that lead to mate! Collected by
Akorps@aol.com. Thanks for that expanded contribution!
- motive.zip Ulrich Haug's collection of tactical test positions, classified by different motifs and difficulties. (+550 positions, most of actual games). Via "themes" key you can select one of six difficulty levels, via "tactics" key different
tactical motifs (like deflection, pin, discovered check, pawn promotion etc.). Thanks to Ulrich!
- t.zip Over 3500 tactical training positions from actual games, collected by Uwe
Auerswald, Zwoenitz (Germany). Many thanks to Uwe! Via "themes" and "tactics"
keys you can select difficulty and various tactical themes (see info-file
in the database).
bestmove.zip Update April 1999! This
is a collection of +2350 training positions (most from actual games), provided
by Ulrich Haug, Ulm (Germany). Verbal annotations are in German. The idea behind the collection is that there is always only one single best (=key) move for every position. No classification of positions according to difficulty or themes. For practical usage random training feature recommended. Thanks
IS A REAL GEM! Over 6600 Test Positions and tactical tests from various sources,
like Reinfeld's "1001 brilliant ways to checkmate"(1001 positions), "Win
at Chess" (300 positions), "1001 Winning Chess Sacrifices and Combinations"
(1001positions); extracts from the "Encyclopedia of Chess Middle Games" (Krogius
et al, 879 positions), "Encyclopedia of Chess Endgames" (Adorjan et al, 1797
positions), Bent Larsen's "Good move Guide" (over 200 Positions); "1234 Modern
Endgame Studies" (Sutherland / Lommer) and some other smaller collections.
These positions were originally collected for testing chess software (file
and distributed via the University of Pittsburgh Chess Archive. The testpgn
- files have the "key move" (= first move of the solution) as the name of
the black player. I removed the key-move information for the collection tp.zip.
If you need a clue for a position in tp.zip, please refer to the appropriate
book (recommended!), or start your Fritz-Engine in CBLight (helps at least
for all easier positions) or look at testpgn.zip (there you will find just
the first move, which is (for me Patzer!!) often not enough in the real hard
positions - eg. for the positions of the computer-oriented "Bratko-Kopec"-test.
