I think that there is another way of looking at this.
Just because everyone says call, including one of the best MTT grinders in the country, I'm not so sure. What we need to remember is that each of these chips has an inherent value, and we can happily wait for a better spot where we have our opponents crushed and get a far better price, rather than, "calling off in a spot where we need to hit to win". A good friend once told me, "you cant spend equity".
I mean, personally, what I would do in this spot, is take a wholly irrelevant life example and draw the thinnest possible comparison, to never quite commit either way, but have fools think that I have. So here for example, its like when you are enjoying a beautiful steak from you favourite restaurant. You are quite full, but this is the best steak you have ever had, and you have 3 mouthfulls left. You could force it all in, thereby reducing your equity (or utility), of the overall meal, but having made sure you got it all. You could on the other hand just leave it, feeling contented right now with your position, waiting say 10 minutes, and then realising you have room for desert too. OK there was lost equity with the steak, but now we are going to devour our favourite cheesecake in a much better spot than the last bit of steak, thereby increasing our overall utility from the experience.
I am definitely a cheesecake man myself. Don't get me wrong, i like steak, but i prefer to get it all in with cheesecake, knowing that once its all in, we can enjoy the result more and the extra on the bill doesn't hurt at all. You could say the cheesecake paid for itself.
