stars $100, final 3 tables. plans to CR foiled by confusing overbet?

[Annulus]

this happened a few days ago. im sorry as i don't have exact information as far as how many left, but i believe it was like 21 or 22 left. 1st place was 8k. we have hardly seen any flops in last half hour. play was fairly standard and no notes/reads of any significance. preflop was standard? is this a good spot for a squeeze? im not sure what my exact plan was on that flop. should i be leading out here? checkraising? thanks for any and all comments.
