chess22k,
an UCI compliant open source chess engine by Sander Maassen vd Brink, written in Java first released in January 2017 [1]. While already in the 2400 Elo range using a 64-bit Java Runtime Environment (JRE), it has not initially implemented a tapered evaluation, but abrupt transition based on piece counts per side to distinguish between middlegame and endgame terms [2][3]. However, tapered evaluation was implemented in chess22k 1.5 along with new evaluation terms adjusted by Texel's tuning method[4]. In November 2017, chess22k had its over the board tournament debut, version 1.6 played the CSVNPT 52 in Leiden, quite successful - shared 4th place with 6/9. Soon released afterwards, chess22k 1.6 requires Java 9[5].
