(check out my "time for you guys to flame me" post for an example, with my reasoning at the end)
You raise for information when you think you have a good hand but don't know.
If you have middle pair, and you want to continue in the hand (early pos) you have 2 options. If you bet, the other person can regard it as a lot of possibilities. If you check, its a big SIGN of weakness OR trapping, one of the 2 (and if they know you they'll know which)
Once they've shown weakness, they'll bet whatever hand they have and you'll result in folding your middle pair! Simple as that.
By betting for information you are:
1) Putting pressure on weak hands ( a call is weak/draw unless you know the player or pre flop action shows otherwise)
2) Not letting the other player know your hand
3) Giving yourself a more aggressive image which you need for your better hands
4) Betting for information coincides with continuation bets which is needed for any poker player.. bluffing
/continuation bets are naturalwhen a raise is used pre flop.
It is essential to bet for information within poker but has to be used in the right place at the right time!
If its mid stages of a tourny.. you have $5000 lets say and blinds are $100/$200.. and someone checks to your middle pair,, i'd bet $300 into an unraised pot as you'll prob win it. If you get called you can then rethink about the hand, and if you get raised you know your behind. By checking your giving up yoru hand completely, which is fine but if you do that too much you're being too tight!
