    * Games are played with 1 minute per side by default (this can be changed in the settings class). The final tournament time control is TBD, so your bot should not assume a particular time control, and instead respect the amount of time left on the timer (given in the Think function).
 * Your bot may not allocate more than 256mb of memory.
+* If you have added a constructor to MyBot (for generating look up tables, etc.) it may not take longer than 5 seconds to complete.
 * All of your code/data must be contained within the _MyBot.cs_ file.
    * Note: you may create additional scripts for testing/training your bot, but only the _MyBot.cs_ file will be submitted, so it must be able to run without them.
    * You may not rename the _MyBot_ struct or _Think_ function contained in the _MyBot.cs_ file.
