Pound 4 was a tournament held in Frederick, Maryland from January 16-18, 2010. At 347 entrants, this was the largest Melee tournament of all time until EVO 2013. It featured players not only from the United States, but also from Canada, Puerto Rico, Spain, Sweden, and the Netherlands.
This tournament is infamous for SilentSpectre's victory over Armada in the Winners Bracket. As this was the only time the two have met in a tournament setting, this makes SilentSpectre one of the only players who can claim a positive record against Armada.
The prize pool is estimated to have been $5,205, assuming the $15 entry fee applied to prize pool from 347 entrants.
