Not sure if this is in the right forum, so apologies if I've posted wrongly.

I just have a specific hand question and want to know what the right thing to do is. Last night I was playing a 180-ppl tourney on pokerstars. We had got to the middle phase and I was MP1. I got dealt JJ. I raised. Was this the correct time to raise? I know I wasn't in good position but we were well into the game and I was playing quite tight. Anyway, my raise got called by two others. The flop had a A and K. I checked the other two bet, so I folded.

I presume I should have just called instead of raising? Any advice would be appreciated!
