BB is generally a straightforward player, but has displayed some 2nd level thinking. I had JJ a few orbits back and he reraise my flop bet because the flop was low thinking that I missed with overcrads, at least this is what I figured was happening.

This was my 5th losing session in a row and I can't tell anymore if it's bad beats, or if I don't know how to play poker anymore. I don't think I'm tilting, I may be a little weak tight, I don't know if my opponents have picked up on that or not.

It feels like I'm being murdered at 6-max, or at least tortured relatively quickly.

I'm playing on this site because of bonuses but losing more money at this point than my bonus is making me. This is fairly typical of what I have been seeing. The players are generally loose passive with a few laggier players thrown in and the very rare TAG.

It's a good fold. BB is checkraising the field on the turn, which is a pretty strong move. Also, if you call the turn, you're going to fold the river ~20% of the time anyway (when a diamond falls).
