Definetely bluffing is important. It's often a question how good is the board for your opponent, do you have any outs which can improve your hand. Also a tight player will probably fold more to bluffs unless he has a pair or better.
But without trying it, getting far in a tournament is much harder. I agree that push and fold determines if one wins a tournament. But from middle to bubble, it is powerful tool to have enough chips for the push and fold part.
The skillful bluff is the key to success in poker. The most money in cash I lose while bluffing. And when I think opponents are bluffing. But people are more honest than I consider ). This is my weak point.
I Love bluffing online... Sometimes you just bluff, buy we have to becareful with the crazy players..
Usually i bluff with no all in...
Live poker is diferent bust harder.. It's not that easy to bluff with somebody looking inside your soul.
Most players bluff online.
Bluffing online is more dangerous, because you to bet more than in live poker to get your opponents away I think.
On live poker you can get tells from your opponents too, and it helps to make any move, including bluffing.
