Avoid turning high card hands into raises on wet rivers when the opponent's range is heavily weighted toward made straights and flushes.

Flop Analysis

Auto-played to reach this drill spot — you didn't act here, so it isn't scored.

Turn Analysis

Checking back is a solid way to realize equity. The 6s is a dynamic card that completes both flushes and straights, making our high card very vulnerable to a check-raise if we continue betting. By checking, we keep the pot manageable and can potentially bluff-catch or improve on the river.

River Analysis

Raising here is a significant error. While we block some King-high flushes, SB's small lead into a checked turn often represents a range that is either very strong or looking to get to showdown cheaply. Our hand has zero showdown value, but it is not the right candidate to turn into a bluff against a range that contains many straights and flushes. **Ranges:** SB's range is condensed but strong, featuring hands like 5x for straights or small flushes. By raising, we only get called by hands that have us crushed and fold out the air we were already beating. **Blockers:** We hold the Kh, which is irrelevant on this spade-heavy board. We don't block the nut flush (As) or the most common straights (5x), making our bluff attempt highly inefficient. **Math:** We are getting over 4:1 to call, but with only King-high and no draws remaining, we have almost no equity. Folding is the pure play; raising is lighting money on fire. --- > **Takeaway:** Don't turn high cards into bluffs on boards where the opponent has a massive nut advantage and your blockers don't affect their primary continuing range.

Note: Raising with King-high on a board where flushes and straights are possible is a massive overplay; you block nothing of significance and SB's range is too strong to fold.

River Analysis

Once SB 3-bets the river, our hand is completely dead. Folding is the only option as SB is never bluffing into a line that looks as strong as a river raise-fold. **Ranges:** SB's 3-bet range is extremely polarized toward the absolute nuts, such as flushes or the top of the straight range (57s). Even if they were capable of a rare bluff, King-high is the bottom of our range and cannot call. **Sizing:** The 3-bet to 12.6BB creates a very shallow SPR, essentially committing the rest of the effective stacks. There is no room for further maneuvering. --- > **Takeaway:** When you get re-raised on a wet river after showing aggression, believe the strength and fold your air.
