The lamp hanging above Table 45, located in the far corner of the "Black" section, has just burned out, thus leaving Vicky Coren and her tablemates in semi-darkness. The tournament director came over to take them to a new table, but the players objected, saying they could still see just fine. And so they remain.
Coren at least might well prefer the shadows as providing a more suitable ambience for poker. In her memoir For Richer, For Poorer, she wrote of how she was "drawn to poker by [the game's] sordid romance," including "the dark history, the whispering corners" that characterize the game's long, colorful story.
Coren has done well in that seat today, having built her stack up over 90,000. Perhaps another reason for her to wish to remain in that dark corner.
