Optimal time for squeeze?

[Goldenad]

This hand took place deep into the daily double, 19 left out of 1600 entrants. Nato seems like a solid player, he hasnt gotten out of line yet. i was a big stack earlier in the tournament and nato was on my left most of the time, he saw me getting active with late position raises and 3bet me a few times. eventually i became short and played tight solid poker for a good 3-4 levels which allowed me to double up. i have no reads on the flat caller. Do i have enough chips to warrant a squeeze? does squeezing here turn my hand into a bluff? clearly im only getting called by hands that im flipping/dominated by. I assume flatcalling oop preflop is the worst choice, but im not sure if it makes more sense to just fold and find a better spot since the table has been on the tight side and folding to my pushes. so here is the question, which is better:

squeeze > fold > flat-call
fold > squeeze > flat-call

AARgh cant get the converter to work sorry
