I'm probably prone to jumping to quick conclusions based on small sample sizes too quickly. But if someone has two/three instances to open for a steal in an unopened pot and they take those opportunities, I'm quickly assuming that it's not just random variance and they have explicitly incorporated stealing into their gameplan (ie: are very wide).

Similarly I generally extrapolate that someone with a high steal from BTN/CO, is probably lighter than most on HJ as well.

I'm playing bodog now (anonymous - thus low sample sizes across the board) - sometimes these small sample size adjustments get me into trouble, but generally seem reasonable.

In general when widening your 3b ranges OOP I would ask yourself where the money is coming from. Are they folding too much pre-flop? If so, be more likely to 3b wide pre but c/f if they call. Are they calling too many 3b, and folding too many flops? If so, then be more likely to 3b them wide and half pot cb, but shut down when called. Etc.

Good luck moving up!
