<h2 id="history">History</h2>
<p>In the only Computer Checkers World Championship, KingsRow took second place behind <a href="/facts/Nemesis_(draughts_player)/arrw8uTX">Nemesis</a>.
</p><p>KingsRow was stronger than Cake++ in the early years. Cake++ finally caught up with KingsRow and gradually became stronger. 
It competed a 624-game match against Cake++ on <a href="/facts/Thanksgiving/B1f0NtI2">Thanksgiving</a> 2004; Cake++ won 3 to 1, with 620 games ending in a draw.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> As of 2023, KingsRow is better than Cake.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a>
On July 17, 2005, Ed Gilbert completed building a 10-piece <a href="/facts/Endgame_database/PSeEbcYT">endgame database</a> for use with KingsRow.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> It had a size of 214 GB, but in July 2016 it was reduced to 102 GB using better compression techniques. KingsRow supports WLD (win/loss/draw), DTW (depth to win), and MTC (depth to conversion) endgame databases.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a>
</p><p>A version for Italian checkers with a nine-piece endgame tablebase is available, too.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a>
