Lesson
Flush Blockers Are a Trap: Reading Range Improvement on the River
River Bluffing · intermediate · 6 min
Tyler and Eric analyze how river runouts change bluffing decisions after betting turn on a king-nine-eight board with diamond draws. The lesson focuses on why a completed flush can reduce fold equity, how holding a diamond affects turn and river folds differently, and when hands like queen-jack have enough showdown value to check back instead of bluff.
Key takeaways
- Do not assume a completed flush is a good bluff card just because you hold a diamond blocker; recreational opponents will often arrive on flush-card rivers with actual made hands.
- Holding the queen of diamonds can increase turn folds because Villain has fewer diamond draws to continue with, but it can reduce river folds when the flush misses because Villain has fewer missed draws.
- On blank non-flush rivers, Villain may overfold hands worse than top pair, making very low-showdown hands better bluff candidates.
- When the flush completes, the automatic folds can drop sharply because many of Villain's turn-calling draws improve, so bluffing becomes less attractive.
- Before bluffing river, compare fold equity with showdown value; queen-jack may have enough showdown value to check, while weaker hands like jack-ten or ten-seven can be closer to bluff candidates on non-flush rivers.
