If you have trouble on the turn, you should analyze the flop and preflop. Since you may have less accurate renditions at those stages and then you are more likely to make a chain error in the turn. For example: you have Jh-Js in preflop and you open your hand from UTG. The villain call from BU. The flop comes: 4h 7s Th. Your cbet is 75% of the pot. BU calls. And you think you could get money from all the T's that are in his range. He also assumes that he has good tie blockers with his jacks. (Your thinking is correct but incomplete, because V could also have more draws, not just 89s but also 56s; Kxs and Axs, from BU's position).
The turn is Kh and you make a second barrel of a similar size, to continue to print value from all the dominated
hands. Villain BU jam, going 3x pot and you call, thinking you defeat most draws. And that even your Jh still works well against all combos: KX (incorrect assessment).
However, here are 3 more points to consider:
1) The fact that both T and K are hearts makes it more likely there is more TK combos in rank V will beat us.
2) Villain got his flush, which we were supposed to consider on the flop (more flush draw combos, not just the 8h-9h combo)
3) On the flop we should also have considered that our opening range from UTG contains very strong values. Like JJ +. This, coupled with the fact that we have made big bets on the flop and on the turn, makes the presence of dominated hands and weak draws less likely in range V (we block J9; JQ; JA).
So this is a case where not all of the most important factors are considered on the flop. And therefore it is possible to make more mistakes in the interpretation of rank V on the turn.
