The best strategy to win the most HANDS possible is to always raise.
It doesn't improve your cards, but it means people will sometimes fold out, so you get some extra winners. If you want the maximum number of wins per hour, raise it every time. This strategy is also excellent for losing money as quickly as possible. The only way to lose more money is to make sure to fold the river if you hit something!
