This is my first post as I just joined this site. My apologies if I'm not using this application appropriately.

$600 MTT $500K guarantee day 1A out of 4 day 1s. 12% of the field advance to day 2 (33 players) about 50 players remaining
1k/2k blinds
Me-140K stack
Villian 1 100k TAG (solid player played with many times)
Villain 2 400k chip leader, never played with and just sat down at the table

V1 is UTG raises to 6K. Action folds to me in the SB and I flat with JJ, and V2 flats.
Flop
669 with 2 spades
me-check, V1-check, V2 bets 6K. me-raise to 16k, v1- call, v2 calls

Turn
2 of spades
me-check (I have the J of spades), v1-bets 30K, v2-calls, me-fold

river
7 of diamonds
v1 check, v2 check

v1 wins the pot with 79 of hearts (2 pair) and I folded the winner having a better two pair jj and 66. V2 said he had AK with ace of spades.

A lot of different things I could have done but bottom line is that I felt one of them had to have the flush especially after they both called my check raise. I did have the J of spades and could have hit the flush on the river but didn't think that would be good enough with no AKQ on the board. I was obviously wrong but my gut said I was beat. Any thoughts? Thanks and looking forward to being a part of this community!
