Timing Tells

[Reel Deal]

Thought it would be interesting to hear people's opinions on what type of timing tells they believe are relatively reliable. I understand that it might be difficult as I think there are some timing tells that probably apply to poor players (like a snap call = a draw), whereas the same might not apply to a decent player. So, for the sake of this discussion, lets divide the tells into two groups: poor players & decent players. Also, assume these are post flop actions and you're HU with the villain.

Categories - Poor Players:
1. Villain checks - HERO bets - Villain snap calls
2. Villain checks - HERO bets - Villain insta min raises
3. Villain checks - HERO bets - Villain insta shoves
4. Villain checks - HERO bets - Villain times down and shoves
5. Villain checks - HERO bets - Villain times down & smooth calls
6. Villain checks - HERO bets - Villain times down and raises
7. Villain insta donk bets
8. Villain times down and donk bets
9. HERO checks - Villain insta checks behind
10. HERO checks - Villain insta bets
11. HERO checks - Villain times down and checks
12. HERO checks - Villain times down and bets

Categories - Decent Players:
1. Villain checks - HERO bets - Villain snap calls
2. Villain checks - HERO bets - Villain insta min raises
3. Villain checks - HERO bets - Villain insta shoves
4. Villain checks - HERO bets - Villain times down and shoves
5. Villain checks - HERO bets - Villain times down & smooth calls
6. Villain checks - HERO bets - Villain times down and raises
7. Villain insta donk bets
8. Villain times down and donk bets
9. HERO checks - Villain insta checks behind
10. HERO checks - Villain insta bets
11. HERO checks - Villain times down and checks
12. HERO checks - Villain times down and bets

There might be some additional categories that I didn't list... feel free to add those to the discussion. And, feel free to only discuss those which you feel you've seen enough to make a reasonable assumption that such action is usually a reliable tell.

Have at it...
