I had about $3.90 in my stack at that time. I limped in on the button with 2 limpers in front of me (and this is a table where any sort of raise usually means AA/KK/QQ/AK) So the pot is $0.50. I pushed $0.50 after the flop, one caller, pot is now $1.50 when I got my straight.

I contemplated an all-in here, as I have only $3.30 left, but with a higher straight possibility out there, I felt like I'd rather throw enough, but not everything, so if the other guy hit the nuts, he'd probably reraise me and I could fold. So I pushed $1.20 and he called.

So after this, I wasn't really thinking about a possible chase anymore, simply "ah he doesn't have the higher straight" (I'd say the biggest percentage of my money loss comes from disregarding a higher straight/flush when I hit one, so I'm wary of those things now) so I pushed my all-in on the river.

So it probably really was an "ah well this happens" kinda loss? Or is there any justification for being afraid when the 3rd club hits on the river? I'd say no, because really, he paid pot-size for a flush draw on the turn and then 3/4 pot for a flush and gutshot on the river.. I don't think I can be calculating this kind of play..
