Biography

Alexey Pavlovich Sokolsky was a Soviet master whose name is permanently attached to the opening 1.b4 — the Sokolsky Opening, sometimes also called the Orangutan or Polish Opening. Far from being a curiosity, Sokolsky devoted decades to analyzing the unusual flank move and wrote what is still the definitive treatise on it. He was a strong tournament player and a respected trainer in Belarus, where he settled and worked for most of his life. His chess was characterized by a willingness to enter offbeat structures and out-prepare his opponents on his own theoretical ground. He coached several future grandmasters and his analytical work influenced Soviet opening theory long after his death.

Soviet master and theoretician who built an entire opening system around 1.b4 — now called the Sokolsky Opening.

How our Alexey engine plays

Our Alexey personality is built from a 13-stage analysis pipeline applied to historical game databases. Move selection runs through 12 style-scoring layers trained on Alexey's characteristic decisions — opening repertoire, strategic plans, causal chains between themes, and the kind of positions Alexey actually steered toward in real games.

The underlying search engine is a 2630-Elo UCI engine, but its top candidate is not automatically played: the style layer picks the move most consistent with Alexey's historical tendencies, constrained by safety filters that prevent blundering. The result is a bot that plays like Alexey, not just a strong engine wearing his name.
