THUNDER is the name given to two collegiate tournaments. Both were intended to be power-marked, regular-difficulty events with each category written entirely by one person.
The first incarnation of THUNDER was organized by Trygve Meade and written by him, Eric Mukherjee and George Stevens with assistance from John Lawrence and was played in October 2009. It received some criticism for excessive length and difficulty in some questions.
THUNDER II, played in December 2010, was written by Eric Mukherjee, Auroni Gupta, Ike Jose, and Dominic Machado, with some last-minute contributions from others (Jonathan Magin and Chris Chiego are credited). Its average question length and difficulty was down from THUNDER I. It was the only tournament written with the intention of being regular difficulty for the fall semester of 2010.
