Tom Likens,
an American electrical engineer and as AMD employee part of the design team implementing the Zen microarchitecture with the Ryzen series of x86-64 CPUs, first released in March 2017 [1].
As computer chess programmer, Tom Likens is author of the Chess Engine Communication Protocol compatible chess engine Djinn, which was his third attempt to write a chess program.
Tom Likens has been interested in bitboards ever since he read the Atkin and Slate paper on Chess 4.5 [2] (circa 1978).
In 2005, Tom was a bit tired of bitboards and learned towards some type of 0x88 and Vector Attacks [3] inspired by CCC posts of Christophe Théron [4] [5], but finally stuck to bitboards.
