It might have cost you more, but then maybe not. EP you might consider a 4x raise with the 55, then if somebody comes over the top, you can drop the hot potatoes. But more often than not they fold out, and your 55's are profitable. I don't think from EP you want any action with 55 at the FT, so I'm thinking that you want to make the only guy who really has a stake in the pot make a big decision. That would be the BB in general, and anyone else who calls or bumps probably has you beat.
But as played you did fine.
