You have top two pair and a nit checks the river. Big bet or small?
A strong hand feels like it deserves a big bet. Against players who fold most of their range to big bets, size works differently.
The hand
$1/$3 No-Limit Hold'em, 9-handed. You have $500, the big blind has $600. The big blind is a nit: plays very few hands and rarely puts money in without a strong one.
- You
- Button, K♠J♠ (two pair)
- Preflop
- Folds to you. You raise to $15. The big blind calls.
- Flop
- J♦6♠K♣ (pot $31) The big blind checks. You bet $15. The big blind calls.
- Turn
- 9♥ (pot $61) The big blind checks. You check.
- River
- 7♦ (pot $61) The big blind checks.
The pot is $61 and it's checked to you. What do you do?
How to think about it
1. Know your options
It's checked to you and the pot is $61. You can check, bet $25 or bet $50.
2. Ask what a nit calls with
You have king-jack on J-6-K-9-7. Worse hands a nit might hold: ace-king and king-queen (one pair of kings), queen-jack and jack-ten (a pair of jacks), and pocket pairs. Better: sets like jacks, nines, sevens or sixes.
3. Ask how that range shrinks as the bet grows
- Does a nit call a big bet with one pair of kings? With a pair of jacks?
- Which of those still call a smaller bet?
The best size is the one that wins the most over all the hands that call it. Against a calling station, who calls with any pair whatever the size, that points one way. Against a nit, whose range shrinks fast as the bet grows, it can point the other.

The takeaway
Size your value bets for the hands that will call. Against tight players, a smaller bet often keeps the one-pair hands in.
