5/5 heads up live

live shorthanded game that has broken down to just us. we've been playing heads up for about 30 minutes and four hours at the full table. my image is tag. villian is tightish and a little off. not a total fish, just has a slight misunderstanding about the fundementals about the game. villian has ~700. Hero covers.
