56o on button is probably too loose. I can only assume BB is making a stand here as a deterrant to your relentless opens and post-flop bets. Post flop, I mean I like this if villain is chasing flush draws on paired turns, but otherwise when he calls turn we should probably realise he intends to call down to showdown.

78s, this is a really easy cbet. There's worse hands calling, and we don't hate being raised. Turn, as played, this is a clear raise. We don't want to see another spade, he'll call a raise if he has the ace, he won't believe we have a flush because I assume hero has an aggressive image and villain would expect flush draws to cbet flop. River, as played yeah just call this, we're maybe getting a raise called by a king if he's terrible but it's dangerous without reads.
