Hand 8, I think is a call. You have one guy to act after you (that already called your cbet) and his odds would go up to call as well. Did he call? If he goes in then you have excellent odds to chase. Without him in it's still close enough.

I had two hands last week where I was given marginal pot odds and huge implied odds to make a call with a gutshot, but I was sick of chasing and missing and losing money. The nut card came out and the pots were huge multiway. Instead of coming out of a downswing, I lingered a while longer because I was a pansy. I'm not saying you played like a pansy, but don't let fear of losing money in front of taking an educated risk in future hands. GL.
