Today, the "AlphaZero style" is the gold standard. It forced the development of , integrating neural networks into the world's strongest traditional engine. AlphaZero didn't just beat the best players; it taught them that the game of chess was far more creative and aggressive than they had ever imagined.
The most shocking element of AlphaZero’s play—documented extensively in Matthew Sadler and Natasha Regan’s book Game Changer —was its willingness to sacrifice material for long-term positional pressure. Game Changer: AlphaZero’s Groundbreaking Chess ...

This allowed it to "feel" the pressure of a cramped position in a way that traditional logic-gate engines couldn't. The Legacy AlphaZero used a to assign win probabilities
For decades, grandmasters played against engines like or Deep Blue by aiming for "closed" positions where long-term strategy trumped short-term calculation. AlphaZero rendered this strategy obsolete. Unlike its predecessors, which relied on thousands of lines of human-coded heuristics, AlphaZero learned by playing against itself millions of times. It didn't just calculate faster; it understood the "soul" of the position. Strategic Sacrifice as a Standard
