It says last week Wesley So Becomes 2nd Player To Sweep Titled Tuesday
On a day when he played a match in the Champions Chess Tour, GM Wesley So also found the time to win both Titled Tuesday events on February 7. He is now the only player besides GM Hikaru Nakamura to achieve this feat in the roughly one year since Titled Tuesday began running twice a week.
It doesn't say 2x a day so maybe it really is 2x a week but not on the same day. But at least in Wesley So's case it appears to be 2x a day.
Early tournament - Feb07
Late tournament - also Feb07
Question: What's going on? Is it 2x a week but not necessarily both on Tuesday but in this particular case it was now both on Tuesday?
