$3.30 NLHE MTT: good spot for semi-bluff check raise?

[limakpl]

What do you think of my play here.
CO: t2683 M = 12.78
BTN: t21016 M = 100.08
SB: t6210 M = 29.57
Hero (BB): t6377 M = 30.37
UTG: t2297 M = 10.94
UTG+1: t3436 M = 16.36
UTG+2: t3070 M = 14.62
MP1: t2850 M = 13.57
MP2: t2156 M = 10.27

Pre Flop: (t210) Hero is BB with A of diamonds 2 of diamonds
5 folds, CO raises to t176, BTN calls t176, 1 fold,

(Here I don't want to call since i would be playing OOP postflop and it looks like a steal attempt from CO, it is very likely that if btn had a hand he would 3 bet himself since he is aggresive, therefore i decide to squeeze and i think i have pretty good chances of getting away with that. If they 4 bet i'm up against big hand so i would fold if they call they are likely to have wide range of hands JT+ KT+ Ax suited ATo+, all pairs )
Hero raises to t560, CO calls t384, 1 fold

Flop: (t1426) 7 of diamonds 7 of spades J of diamonds (2 players)
Hero checks, CO bets t855, Hero raises to t3991, CO folds

(not bad flop, I have shown an aggresion preflop , ace high flush draw, and i expect about 1/2 pot probe bet which would live villian with 1400 left and 2100 in the pot) Villian bets a liitle bit more and i check raise knowing that is very unlikely that flop improved my opponent and he gets about 3,5 odds on his call. I figure out there a big chances that he will fold and even if he will call i have big chances to improve to the best hand.

Would you play this hand differently and why ?

Final Pot: t3136
Hero mucks A of diamonds 2 of diamonds
Hero wins t3136

I like the line. Especially if we think he is light and unlikely to be beating us. If we wait on the flop we can use his own momentum against him.

I'm curious on how we pick sizing for squeezes. I know that it's generally in the neighbourhood of 3x a raise to 3 bet OOP. How do we change the size when there are flats?

Also what are the blinds?

I don't like the squeeze preflop. I would just flat with this hand.

As played, the check raise jam on this flop is a beautifully executed semi bluff. His range is unlikely to have any 7s in it; and he has a lot to be afraid of; so you'll get a lot of folds. He is unlikely to hold a monster like KK,AA since he didn't 4bet preflop. his AK/AQ hands should fold and all of his 88-TT hands will probably fold as well. so you're really only in trouble vs AJ or QQ. most of his range is folding here, but when he does call you've still got a lot of outs.
