Chess 2020 [1]

Chess 20xx,
a series of Windows chess programs developed by Filip Höfer, Chess 2012, Chess 2013, and Chess 2020 all in 32-bit and 64-bit editions. The "chess AI" is conventional alpha-beta with iterative deepening [2]. Free versions provide basic functionality (Chess 2013 for two hours), while the commercial edition enables all features


The proprietary GUI provides a single document interface with classical menu- and status bar. The main window, dominated by the isotropic 2D graphics board, has several frame boxes arranged for game notation within a single column list box, principal variation, chess clock, and evaluation scores. A progress bar indicates "thinking" time allocated and current usage, and four context sensitive dialog-styled push buttons simplify game navigation and control.

Chess 2012

Chess 2012 was the first edition released in 2012 for Windows 7/8/Vista/XP.

Chess 2013

The commercial Chess 2013 provides a choice of visual styles for the chessboard, chess pieces, and the background. According to its author, it has improved by ca. 100 ELO points over Chess 2012 [3].

Chess 2020

Chess 2020 comes with a improved GUI and endgame play, extends the support of PGN, FEN and UCI, and is about 30 Elo stronger than 2013 [4].
