Colditz Test
A collection of 30 tests to identify tactical play strength. Originally written by Karl Colditz in the book "Lern-, Practice and Chess Combination Tests", these tests are also well suited for testing the tactical strength of weaker chess computers (up to 1900 Elo). Evaluation is based on the software EloStatTS 1.0 using 1800 ELO points as a starting value.
Each test is timed until the correct move is shown in the display using the Analysis Level. For computers without a display, a more intensive method is used: replaying positions at different levels to find the minimum time required for the correct move. The highest allowed time per solution is 30 minutes.

Instructions & PGN
Times shown after the slash (/) were taken from CSS. Example: 'Mephisto II/1802-6.1MHz' 1200s / 25. Unfortunately these were not always complete. For position #101, an average value was chosen.
"Hopefully the true values were not too badly corrupted because of this. It would be best to re-test any questionable results."
