I'm trying to get an idea of how to play some hands where I've taken bad beats, but where my odds of winning were only around 50%.

3rd hand of the night in a PP 30+3 3-table tourney, blinds(obviously) still at 10/15. I get AK off in middle position, 3 callers in front. I raise to 60 and get 4 callers, with the guy right in front of me going all-in after previously just calling. I call, and then a guy right behind me calls as well.

What would you have done? Results in white:
<font color="white">First all-in has AJ off, guy behind me has A10 off. Flop has a 10 in it, idiot wins. </font>

I'm not sure if I should be waiting for hands when I'm dominating someone, or if I should be willing to go all-in with even a slight advantage...
Thanks for any help.
