For me, the biggest adjustment was learning how to represent. At $2nl it's all fit or fold poker and value betting is god.

At $5nl value betting is still god, but you can really start firing on scary flops, turns and rivers. If you see someone with 22%+vpip and 55%+ fold to c-bet, you're going to be taking a lot of flops off them.

Just some food for thought, good luck as always Vinland.
