Trying out NL SNG after a long hiatus

[Cookie Monster]

After a 3 year break from poker (small stakes limit) in which I was fairly successful thanks to this forum I am trying out NL SNG tourneys. Only play money right now while I get the hang of it. I find it pretty easy to make it into the money almost every time but have not yet figured out the short handed, high blind end phase yet. Case and point with the following hand.

Both my opponents were calling down what seemed like every hand. I meant to go all in after the flop but misentered my bet. Any advice would be greatly appreciated.
