Oxford Softworks & Chess System Tal 1982–2000

British chess and games programmer, publisher and entrepreneur, founded Oxford Softworks in Burford, Oxfordshire in the mid-1980s and spent two decades building chess engines — from SuperChess (1982) to the Complete Chess System and, above all, Chess System Tal, designed to play in the romantic, sacrificial style of World Champion Mikhail Tal. Oxford Softworks became a software development, licensing and publishing house specialising in strategy games — Bridge, Go, Shogi and others — and was sold to venture capitalists in May 2000; the chess engine never retired, and Chess System Tal lives on today as a modern neural-network (NNUE) engine.

Worcestershire Sauce 2000–2010

After the sale, Chris retired (sort of) to a riverside house near Pershore, Worcestershire and turned to other pursuits: vegetable patch, beekeeping, alpacas, sheep, pigs, cows and river boating, programming remaining a part-time pursuit including a neural-net Backgammon project and a stock-market analysis tool (these never work btw — there is no way a retail investor can get ahead of the market sufficiently to overcome trading friction). For a time he also served as Chairman of the Parish Council, handing over to the capable hands of Bob Annis in 2009.

France 2010–present

In 2010 was the move to a farmhouse in south-west France — bees, honey, vegetable patch, carpentry workshop, generally things rural — until there came AlphaZero and AlphaGo, the big shock from DeepMind that neural nets could do what was thought impossible: play chess above Grandmaster level. So, back to AI and machine learning — that was some catching up to do, discovering the strange thing called NNUE and, of course, what better way to learn than to do it oneself, or, as it turned out, twoselves.

Veteran Grandfathers of Computer Chess 2023–present

Thus was Chess System Tal NNUE, and the development partnership with veteran chess programmer Ed Schröder of Rebel fame, born.

Nomad Adventurer — South-East Asia & the Caucasus 2025–present

Since 2025 Chris turned digital-nomad-adventurer, keeping the French farmhouse but much of the year now spent in South-East Asia and the Caucasus. With a couple of laptops and an internet connection, the development of a new Chess System Tal 3 has begun. All good and promising so far. News as it develops…

• Chess engine design
• Evaluation & search
• NNUE neural networks
• C / C++
• Forward pruning
• Games publishing

One preference runs through all of it: knowledge over brute force. Where most of computer chess leaned on ever-faster, ever-wider search, the bet here was on encoding real chess understanding instead.

Core philosophical pillars

• Knowledge over search: deep, wide-scale searching — "counting beans" — does little for genuine chess understanding. Better to build real chess heuristics and strategic judgement directly into the evaluation function.
• Romantic, attacking style: Chess System Tal (CSTal) was built to play in the daring, speculative spirit of World Champion Mikhail Tal — human-like chess that prefers bold sacrifices and tactical richness to dry, materialistic, defensive play.
• Closing the "search gap": engines that lean on enormous search depth often produce moves no human can explain — "hidden minefields" with no discernible plan, which makes them poor teachers. The aim is the opposite: moves you can follow and learn from.
• A human-friendly engine: at heart, the ideal is a sparring partner — one that trades a little raw tactical depth for more educational, plan-led games, where the reasoning behind each move is something a person can actually grasp.

Historical context & impact

• Oxford Softworks: through Oxford Softworks in the 1980s and 90s came titles like Chess Player 2150 and Chess System Tal — strong for their day, and notable for a "selective", strategic approach rather than brute force.
• Beyond bean-counting: a recurring theme is some scepticism about the field's focus on Elo ratings and engine-versus-engine testing, which can yield programs that are tactically fierce yet hard for a human to engage with strategically.
• An alternative path: an "alternative pathway of idealism", as it's sometimes put — a different road through a field largely fixed on maximising speed and nodes-per-second.

In short, a counter-current in computer chess: the idea that chess intelligence is best expressed through structured knowledge and creative heuristics — not raw search power alone.
