Getting more aggressive

Heya all. I've kinda just started out at $25NL over the past week or so and I've been playing pretty tight basicly following Aok's 19 hand preflop strat. While I still think it's a great strat I feel like I could be eeking out some some more profit if I were more aggrressive and or looser in certain situations. Any ideas?

Raise more, call less.

Are you sure you don't mean call more raise less? If I'm raising people will leave the round then I won't be able to hit the straight which beats the flush cuz straights are lucky.

Bet anything with value. Don't semibluff a lot though, there's no FE at 25NL. Save that for 50NL.

When in doubt if you're ahead or not, raise.
