Pocket pairs? It depends....it all depends. On position, the types of players that are at your table, tournament vs. cash game, etc.
As most have said, 10/10+ is a good raising hand in any position, again, depending on the action. 22-99, I play cautiously. Think about it....you only have two outs to hit a set, which is really the only way these hands are strong. Calculate your odds vs. how much it's going to cost you to call. Then, be aware of over cards, straights, full houses (pair on the board, giving you two-pair, but the other guy a boat), and flush draws. To me, in most situations, the risk outweighs the profits, unless you have a great read on your opponent.
By the way, my aces were cracked today by someone who called an all-in raise with 3/3....no, he didn't make a set, he made a 4-card flush (4 diamonds on the board, and he had the 3 of diamonds). Wonderful, just wonderful.
See you at the tables
