Live 5/10 huh?

[Jeebus]

Just sat down at the table about 5 hands ago, villan has played everyhand for whatever that is worth.
Hero has 1K in MP
Villan covers barely on button

one limper to Hero, I raise to 30 with KhKc, CO calls, villan raises to 50, fold to me I raise to 100. BB calls
Flop (255 in pot)
5h 2s 7h
hero bets 225; Villan pushes. Hero?
Would a check raise have possibly been a good play here? I thought about it but didn't want to give a free card to something like AhKh or really any ace.
