Fellow developer Larry Kaufman said AlphaZero would probably lose a match against the latest version of Stockfish, Stockfish 10, under Top Chess Engine Championship (TCEC) conditions. Kaufman argued that the only advantage of neural network–based engines was that they used a GPU, so if there was no regard for power consumption (e.g. in an equal-hardware contest where both engines had access to the same CPU and GPU) then anything the GPU achieved was "free". Based on this, he stated that the strongest engine was likely to be a hybrid with neural networks and standard <a href="/wiki/Alpha%E2%80%93beta_search" class="mw-redirect" title="Alpha–beta search">alpha–beta search</a>.<sup id="cite_ref-27" class="reference"><a href="#cite_note-27"><span class="cite-bracket">&#91;</span>26<span class="cite-bracket">&#93;</span></a></sup> </p><p>AlphaZero inspired the computer chess community to develop <a href="/wiki/Leela_Chess_Zero" title="Leela Chess Zero">Leela Chess Zero</a>, using the same techniques as AlphaZero.
