The draws missed and an aggressive player bets the river. Call or fold?
Folding to every river bet is as costly as calling every one. Against players who like to bluff, the question is whether the bluffs are really there on this board.
The hand
$1/$3 No-Limit Hold'em, 9-handed. You have $230, the big blind has $300. The big blind is an aggressive recreational player: plays loose and likes to bet and bluff.
- You
- Button, Q♦J♦ (top pair, good kicker)
- Preflop
- Folds to you. You raise to $15. The big blind calls.
- Flop
- Q♠T♠2♣ (pot $31) The big blind checks. You bet $15. The big blind calls.
- Turn
- 5♥ (pot $61) The big blind checks. You check.
- River
- 9♥ (pot $61) The big blind bets $40.
You have $40 to call into a $101 pot. What do you do?
How to think about it
1. Work out the price
You call $40 to win a pot that will be $141. So the call needs to win more than $40 ÷ $141 = 28.4% of the time to make money.
2. List the draws that missed
The flop came two spades. Neither the turn nor the river was a spade, so every spade draw missed. Against this player that matters a lot: a missed draw can't win at showdown, so the only way it can win the pot is by betting.
3. Check what got there
The 9 on the river isn't harmless. It completes straights for king-jack and jack-eight, which beat you. Be honest about how many of those hands are in this player's range compared with the spade draws that missed.
4. Ask what this player does with a missed draw
A general rule from our opponent models: aggressive recreational players often turn missed draws into river bluffs, including large ones. Against this type, a bluff-catcher like top pair is exactly the hand that's meant to call. Against a nit, the same hand on the same board can be a fold.

The takeaway
A river bet means different things from different players. Count the missed draws, count the hands that got there, and then ask how this particular player plays a missed draw.
