History
editRichard Vida started working on Critter in late 2008. The first version was originally written in Object Pascal but the code was later converted to C++ using Bitboard technology because Delphi did not perform well under 64-bit processors.[5][6] Critter had its over-the-board (OTB) debut at the ICT 2012, where it became a strong runner-up behind the Rybka cluster.[7]
