So many idiots playing online, especially in lower stakes games. Your only real mistake might have been shoving because that usually invites a poorer player to call. Had you made a high value looking bet, perhaps the other person would have folded. The reality is that there are so many people playing who have money to burn that they just don't play percentage poker and it ends up being a complete crap shoot most of the time. Yes, in the long run you want the call, but it's pretty hard to see the forest when there are so many trees who are basically clueless. Remember, the lower the stakes the lower the percentages any good hand has, because there are so many additional variables (donks who don't know any better or don't care).
