they're great hands to play later on too...if you have the stack to. especially with position. i'll go ahead and limp if there's limp action before me (unless i'm pretty sure what previous limpers will do...fold, if i raise), or raise from later mid-pos with them. there are times you can treat these hands like AK/Q/J depending on your opponents...though they can easily be crap in really loose
freerolls. from 23 (if you have balls) to KQ, you'll often have a lot of outs post-flop, and have plenty of opportunities to scare ppl off the pot provided there's weak betting.
when you're looking to open your range in a tourney...they really are a good excuse to open up any hand...and, importantly, they're easy to fold if things just don't work out. they're killers against anyone's AA/KK/QQ/JJ who didn't raise enough preflop either (like a min-raise) and can provide a nasty uppercut to anyone not playing their hands correctly.
one thing i've been wanting to work on is to play more of them...especially as an excuse to just get into more hands because i all ready know i play too tight
