You can not risk giving a free card to 3 other players. Your hand is a strong holding but not invincible. Heads up, you might want to try a check raise there, but not with 3 chasers on 4th. 5th strt raise looks ok. check on 6th is smart as it looks like he made flush. Fold on river is excellent.

It is not clear if a bet on 4th by you would have changed the outcome but nonetheless, they are on your tail. Most situations call for straight forward play and not trickery. And if all your plays are trickery, then is anything you do trickery?
