Its fine to say, I am too passive etc etc, but its important to understand WHY raising is correct here.

Anyone with a flush or straight draw, hell most people with two business cards in their hands are not leaving such a big pot so you need to raise with the equity edge.

If you lose a couple limpers this is fantastic especially if they held a heart.

You want to take down big pots as quickly as possible, you raise here not only for value but also to potentially increase pot equity.
