100 NL - Bad Beat or Misplayed

[crewshell]

I'm new on the board and semi new to poker, been playing at commerce in Los Angeles since Nov of 05.

100 NL Table
I am UTG and limp in with K [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/club.gif[/img]
3 callers then button raises to 25, he'd been bluffing alot throughout the night and was known to steal pots. Buttons fold - I call, UTG+1 goes all in for 28, everyone else folds, Button and I call the extra 3 bucks. Flop comes 3 [img]/images/graemlins/spade.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] 10 [img]/images/graemlins/club.gif[/img], I check, Button goes in for 50, I move all in with 110 left, button calls, I flip over KQ, he flips over KQ but both spades, he turns a 2 [img]/images/graemlins/spade.gif[/img] and then 6 [img]/images/graemlins/spade.gif[/img]'s --

Did I miss play this? Just get a bad beat? Also I prefer 100 NL cash games, can anyone suggest a good book? I've read a few but they were geared towards Tournament play.

two weekends ago i won 1200, then I lost 1300, this past weekend I won 1060 but lost 500 last night. So I am up since i picked the game back up several weeks ago but a bit frustrated that I am on such a roller coaster. I tend to play tight aggressive but I tend to favor suited middle connectors and puddle hopers more then I probably should.
