Brainburst.com
Brainburst.com is a site dedicated to tournament level players. It features daily articles about the various game formats. There was a time when Brainburst had several of the best strategists writing for them, like Zvi Mowshowitz, Mike Flores and others. Nowadays, many of those big starts have jumped ship to StarCityGames.com. While its importance has slightly deminished, some top players, like Antonino de Rosa and Frank Karsten, still contribute to the Brainburst site.
