Say we are late in a MTT. Around 350 joined and the blinds are 1000/500. The blinds aren't being contested too much. How often do you try to steal them? I try to at least once per orbit and maybe twice. Is this too much? Does it vary from table to table? Let's say i'm 2nd or 3rd in chips at the table with an M a little above 12. (M is the total of the blinds in comparison to your stack. so 1500 * 12 = 18,000 chips).
The reason I ask this is because I always feel like i'm asking for trouble stealing so often. I like to stay under the radar and not have everyone at the table wanting to take me out.
