Thoughts? I'm getting 1 to 1 odds on my money. Do you think CO will fold more than 50% of the time?

You are not getting 1-1 odds for your bet. The 1200 you already put in the pot is not yours anymore.

You are betting 1800 to win 3000. Your odds are 5-3. If he folds more than 37.5% of the time you are ahead.

I say 1 to 1 in regard to the entire move. Obviously I'm not calling the flop because i think i can catch up on the turn. On the flop the pot was 1800 + my opponents 600 bet. I need to call 600, and bet 1800 on turn. Thus I am paying 2400 for 2400, i.e. 1 to 1.
