In my opinion, playing as many hands from the small blind as you can is a must. UNLESS they are extreme garbage, I will almost always play to the flop, especially if I am holding a lot of chips.
This is very bad advice...
You want to have hands that play well in multi-way pots since most of the time if it is only half a bet to you there have been many limpers in the hand. Hands such as suited connectors (56 and above) pocket pairs (play the small pairs for set value only), and two large cards are ideal for calling when in the SB. Don't just call for the sole reason of seeing a flop, have a decent hand...
Even if you hold a lot of chips, you will lose a significant portion in these stupid calls from the SB with bad hands. Sure 1/50 times you will hit a boat or something, but this is not a reason to limp bad hands no matter what.
The SB is the worst post-flop position, you really only want to continue after the flop with hands that hit a large piece of the flop ( ie. top pair, open-ended straight draw, flush draw, etc.)
