I think you're getting check-raised here close to 80% of the time.

Isn't that good?

Yeah, I thought I was. But if I can only improve my chances of winning by something like 5-8% - (2*.8[c/r] + 1*.2[called])/Final potsize - then it is worth it.

Does the bet increase my chances of winning by 5%+?

I figured there is a small but significant possility I am ahead. By checking the flop I pretty much give up on winning without improvement?

My bet + opponents c/r might get hands like A2, Q2 and maybe even A8, Q8 out. Insignificant?

If I get called then on the turn I can either fire again or take a free card.

All of these factors seem kind of vague to me. What do you think? Are there enough? Is there more to consider?
