I love pocket pairs because they are very easy for me to play. If I hit the set, I look to milk it if no trouble on the board. If trouble, I look to take it down. If I miss the set, I only stay in if the board isn't threatening and mostly/all undercards.

Same thing with Axs. Hit the flush, milk it. Miss the flop, look to get out unless pot odds allow me to draw for cheap.

I have the most trouble with AT, KQ, KJ. Usually hit a flop that's not good enough to own but not scary enough to fold. I'm looking to improve that however. I looked back and saw KK and KQ were my biggest losing hands. I have large negative profit. KK ran into well disguised hands like low trips too many times. Plus, lost to AA several times. Not tons of loses but whole stack loses. Just have to learn when to lay down KQ even when I smell bluff.
