Often in a tournament I may get to roughly twice the chip average let's say. Sometimes I'll go a long period of time where, for 1 reason or another, I don't get a hand that I can commit to - usually bad hands, but could be in bad position, you get the idea. I find myself at half the chip average or even worse when I finally get a hand I can play.
This is a common experience for most solid tournament players. Some suggestions:
Check that you are not being overly nitty. Even a TAG player should have a VPIP of approximately 17-19%. If you are consistently less than this over several tournaments, widen your range of opening hands somewhat, especially from late position.
Assuming that your playing style is not at fault and you genuinely are card-dead, steal as others have suggested. Study the opponents in the four seats to your left and target any who seem weak-tight.
You should also think in terms of restealing from any players to your right who appear to be more than averagely aggressive.
Study the squeeze-play tactic (too complex to explain here, don`t want to hijack the thread - try a search, or I might write a piece if there isn`t an explanation already on CC) and look for opportunities to apply this, especially against tight opponents.
Finally, watch that stack size and don`t allow it to get much below half of average stack. Better to make a move in a marginal situation, a coinflip or a draw, and look to double up or bust out. Short-stacks don`t win tournaments and it`s better to save your time and move on. There is always another tourney to play, and you should be playing well within your
bankroll, such that the loss of one buyin is not a concern.
