Check raise vs Leading (forcing your oponent to draw out)

[A_PLUS]

8 person, 20$ home game with payout of 120/40$. Begin with 2250 TC and blinds 25/50 raising every 20 minutes.

7 players, I have apx 2000 TC, blind at 50/100, I open for 300 with QJo. I get called by a TAG and LAG.

flop comes JJ6 two spades, I hold Qs.

Here is my thoughts:
The LAG, would have reraised me preflop with AJ, maybe with KJ, and will make my flop bet for me if it is checked to him. The TAG, will probably check-raise the flop with AJ, KJ, so any bet is most likely a value bet with a PP or possibly a flush draw.

Actions:
I check, TAG bets 500$, LAG calls, I reraise all-in for another 1200.

LAG calls me and I get busted by a flush on the river.

Given the fact that I went for the check-raise I know we both made the right play. LAG had 4000+ TC. So how do you feel about the CR vs. the opening raise on the flop.

What type of situations do you think it is correct to go for the CR vs opening raise (lets assume for arguement that we are CERTAIN that the flop will be bet).

This is in context of a STT, where you think you are the best player remaining. I already understand the TC EV end of the arguement, I would apppreciate any strategy discussion.

Thanks
