Was it worth betting on the turn? Or was it better to initially play a check / call?

The line u use is fine,you had K high(in heads up you can take as value even a Q high) and second nuts flush, betting is a fine line because you have the fold equity on your side,when he raises you jamming the turn i dont like the call you can be even lousing to the A high off diamonds.
So it is ok to bet thouse caind off hands,but when vilain raises you is beatter to fold

I think, its fine betting with the second nut flushdraw. There are lots of hands, that will fold the flop or fold the turn. Its not ideal to get jammed on, but this will not happen all the time, and its baked into the whole equation. At least you have a simple math based decision, when he jam, and since pot odds are not good enough to draw, its an easy fold.
