This hand is against a loose/passive/aggressive player (~45/5/2.5). Since moving up I find these situations occur alot more frequently than at $50 or below and I'm never sure what to do. I open raised on the button the hand before and took the blinds and have a TAG image. What's the play and plan for future streets?
