Giving up to Early?

[stoli]

I wanted to know if I gave this hand up too early or how you some of you would play this. This was the second hand I was dealt after being moved so I had no reads available. We were down to under 1,000 players at this point and the previous table was fairly tight.

I struggle with hands like this I think. From my Limit games I guess I get the idea this needs to be raised but I guess maybe not in a NL tourney?? Also I do concede that If i'm going to raise, it probably needs to be more than this to discourage people from calling.... I don't really know why I raised this, I think I must have used the slider bar thing and not gotten it to 450. Thanks for the help.

Final Pot: t2500

I made the flop bet assuming this was my only opportunity to win the hand. Either he'd come over the top or fold. The call kinda throws me and I pretty much concede the hand at that point absent of reads on the sb.
