Pretty deep hand early on from WSOP

[wpr101]

Effective stacks are 44k on the second 100/200 blind level. Guy who has me covered raises UTG+1 to 600, 1 caller right next to him. I call out out the BB with 67s. Original raiser is uncreative tight player.

Flop (pot: 1900): Flop 459r. I check, original raiser bets 1300. I cr to 4500, he makes it 10k total and I call.

Turn (pot: 21900): ten (459rT). Goes check/check.

River: is another 9. It completed runner/runner flush too. Best play to check fold?
