I don't play this high and it sure does look like Kh but I cant fold a straight flush. I mean the chances that he misread the board and doesn't realize 4 card sf draw is there and is shoving a boat or Ah is enough to make this a call for me and then curse the gods when he indeed has the King. Or he could think your spazzing with Ah and he has a boat IDK. That's how I justify my bad calls prob .
