Huge flopped straight with straight flush redraw

[BobboFitos]

What a beautiful flop and subsequent action.

On the turn, as others have pointed out, it's time to put the breaks down. If you had a read he liked to snuff out weak bets - so a small bet would induce a raise - or would try and take away the pot from a AK / AQ (or worse!) hand, then a check has merits.

But most of the time Im betting, and Im betting big.

On the river, given way that it was played, he could have higher spades, I dont see a boat here (likely plays flop and/or turn faster) and you're getting a good price. I call, but I wouldn't like it.
