Flop Analysis
Checking is a fine mix, though betting small is preferred to leverage our range advantage on a King-high board.
While we found a pair on the river, we overplayed it by turning a bluff-catcher into a massive over-bluff against a range that contains many flushes and straights.
Checking is a fine mix, though betting small is preferred to leverage our range advantage on a King-high board.
Stabbing small is acceptable, but checking back to realize our equity with the nut flush draw is often higher EV. **Board:** The 6s is a highly dynamic card that completes several straights (95, 54) and brings the flush draw home for any 2-spade holdings. **Ranges:** BB has a significant nut advantage here with more 95s and 54s in their defending range than we have as the LJ opener. **Sizing:** If we do bet, the solver prefers a larger size (80% pot) to polarize our range; our 1.5BB bet is too small to put pressure on BB's marginal made hands. --- > **Takeaway:** On cards that complete multiple draws, prefer checking back high-equity draws to realize your equity for free.
We hit second pair, but the board is extremely wet. Betting for thin value is okay, but we must be prepared to fold to aggression. **Ranges:** Our range is quite condensed after checking the flop and betting small on the turn. BB's range contains all the flushes and straights that we lack. **Blockers:** Our As is a double-edged sword; it blocks the nut flush (good for us), but it also blocks the hands BB would most likely be bluffing with. **Sizing:** A medium sizing (66% pot) is appropriate for thin value against 8x or 7x, but it's a thin click given how many better hands BB can have. --- > **Takeaway:** When you improve to a marginal pair on a completed board, keep the pot small as you are often either way ahead or way behind.
This is a massive overplay. Raising over a river check-raise with second pair on a four-straight, three-flush board is turning a hand with showdown value into a pure bluff. **Ranges:** When BB check-raises this river, they are extremely polarized. They either have a flush/straight for value or a total air-ball bluff. Our pair of Jacks beats only the bluffs. **Math:** We are facing a min-raise, giving us 2.2:1 odds. While the price is tempting to call, raising is never the play. We lose to all value and fold out all bluffs. **Position:** Being IP, we had the chance to just check back the river and realize our showdown value. By betting and then 3-betting, we've maximized our losses against a range that has us crushed. --- > **Takeaway:** Never turn a bluff-catcher into a bluff on a board where the opponent can easily have the nuts.
Note: 3-betting the river with second pair is a massive error; you lose to all value hands and fold out all bluffs you were beating.
