Tuesday Night Tournaments are held every month of the year, except for December when things are organized a little differently.

In the past few years the year end TNT has been played over 4 Tuesdays in November and 2 Tuesdays in December. This year end TNT is called the Mike Shpan Memorial TNT in honour of the former MCA Board member, longtime Membership Coordinator, and Wednesday Night Drop-In host at the Cornish Library, Mike Shpan. In 2007, the Mike Shpan Memorial TNT was played alongside the Grand Prix tournament.

All of the TNTs are Swiss (pairing) style tournaments with a time control of all moves in 120 minutes, or all/120. The TNTs are typically 4 round events, except for months with 5 Tuesdays in which the TNTs have lately been 5 round events. However, Tuesday, July 1st is Canada Day, therefore the first round will be held on Tuesday, July 8th. Start time is 7:00 pm and the TD will confirm costs.
