Example spot that the vast majority of micro players get wrong.
UTG opens AA for 3bb, CO, BTN and BB call. Flop comes JT6tt. Nearly all beginners think "It's a wet flop. I should bet big to charge the draws and get value from Jx". But betting big in this spot is a blunder. AA should be a very clear check, and it's debatable whether you should c-bet anything at all.
Just consider when the villains have JJ or TT or 66 or JTs. The last thing you want to do is pile in loads of money drawing almost dead. If they have 88/77 or A5s they were never giving you any money, so c-betting has no purpose against those hands. If they have QJ, or KQ, they will likely put money in the pot anyway, but you need to be cautious in case the turn is an Ace, king, queen, jack, ten, nine, or six, all of which put many combos of 2prs, trips, straights, boats into your opponent's ranges. By check-calling you lose the minimum when you're way behind, but can get to showdown when villain bets once or twice, by check-folding (when there's a ton of action), you lose nothing at all. By betting, you allow your opponents to play perfectly, and often just build a pot that ends up as part of someone else's stack.
