My biggest hands from my 1k sesh tonight.

And if you're going to raise, raise quit a lot bigger. They are limping with T7o, Q2s etc, so you want a hand that can make a decent TP hand. - 66 doesn't have a lot of equity against random trash, and they're definitely not going to make a mistake by folding too much to your cbets.
QJ would be a much better hand to raise there than 66.

Even in position I think you should be limping behind with hands like sc's, small pp's, and stuff like J8s rather than isolating.
