'''Gustav''',<br/>
a [[:Category:Problem|program for solving]] orthodox [[Chess Problems, Compositions and Studies|chess problems]] by [[Olaf Jenkner]], written in [[Delphi]] <ref>[https://www.stmintz.com/ccc/index.php?id=158578 Delphi/Kylix Compiler] by [[Olaf Jenkner]], [[CCC]], March 14, 2001</ref>, program texts and manual available in German only.
Initially developed since 1990 for the [[MS-DOS]] operating system in [[Pascal]], Gustav was later ported and improved to run under [[Windows]]. Gustav is able to solve [[Checkmate|checkmate]], [[Stalemate|stalemate]], [https://en.wikipedia.org/wiki/Helpmate helpmate], helpstalemate, [https://en.wikipedia.org/wiki/Selfmate selfmate] and selfstalemate in N moves.
It has a dedicated [[GUI]] with various dialog windows to edit positions, to load and save [[Forsyth-Edwards Notation|FEN]] or proprietary GST-files of problem collections, and to control the search.
Beside [[Brute-Force|brute-force search]] accelerated by a [[Transposition Table|transposition table]], several automatic or user defined constraints such as number of escape squares for the checked king, allow shallow and deep searches of up to 170 moves (339 plies).
The longest for Gustav solvable problem so far has 163 moves, a composition by [https://en.wikipedia.org/wiki/Ott%C3%B3_Bl%C3%A1thy Ottó Titusz Bláthy] <ref>[https://www.schachversand.de/en/gustav-4-0-i.html Gustav 4.0] from [[Schachversand Niggemann]] (German)</ref>:
