Tayvok

Tayvok was a chess master and analyst who lived prior to the 22nd century. Sometime prior to 2156, Tayvok invented the Tayvok's Gambit.

Trapped on the Caeliar city-ship Axion following the destruction of Erigol and the deaths of their colleagues Sidra Valerian and Johanna Metzger, former Columbia Earth Starfleet Captain Erika Hernandez attempted to use chess as a medium to reconnect with her estranged first officer Veronica Fletcher. Fletcher initially hid the chess board, but eventually relented, and Hernandez utilized Tayvok's Gambit to position her pieces in a favorable arrangement.
