Hello there!

I have found a big leak in my tournament game so far.
After looking at Pokertracker i noticed that i can see how much T$ i earned from each position. Interesting to note is that i lose T$ on 4 positions being : BB, SB, Button+2, Button+4.
BB : 16,230
SB : 12,790
B+2: 1,990
B+4: 1,695

The difference between total T$ won and lost is only 1,220. So it seems i lose all my hard earned T$ in the blinds.

How should one play blinds at different levels? Currently i dont bother at all with blinds untill i drop below the 20 BB mark. After that i inspect the person that is raising to see how often he/she raises in attempt to steal the blinds. If it is 3 or more i reraise three times his/her raise, no matter what my cards. However if somebody raises in early position and somebody calls i will just fold and wait for next time.

I also think i am a bargain hunter and that gets me into trouble. I play speculative hands because i am getting a cheaper price to see the flop, and then run into big hands later on.

What should i do to play better blinds poker? Play more passive ? Tighten up? Keep an better eye out on positions etc?

Any comments and replies will be grately apreciated.
