I've written a longer article about some of the common mistakes I see at low buy-in No-Limit Holdem games with playing hands like medium and small pairs and suited connectors. These hands are longshots preflop, and so they depend a lot on implied odds.
It's called Small Pairs and Connectors in NLHE. There's a link to it in the Articles section in the upper right, or you can click here.
I doubt that any of the article will be news to even moderately experienced NLHE players, but it may be helpful to people who are newer to the game.
