In addition to the good suggestions so far, I have found a really good note is to track the "flush masters" (keeps all sooted) and the "ace masters" (keeps all Aces)
I am a lot more wary on a 3flush board when I have a flush master in the hand, and the A on board slows me down more when there's an ace master in the hand (unless I have one!).
Of course, this is about 90% of all players at the bargain levels where I play
