Question about how to play early in 3-table multi

[obisponator]

My friend and I have a fundamental difference of opinion on how to play multi-table tournaments. My belief is that you should portray a tight aggressive image early on then use that image when the blinds gets big to accumulate chips. He thinks that you should give yourself a chance to accumulate chips early so you can use your stack later in the tournament. So, the question therefore is, we have KJo UTG when the blinds are 10/20 or level 2. He thinks limping is the correct play and I said fold. What is the correct play and also which of our strategies is best? Thanks.
