I am looking at http://www.pokerstrategy.com/strategy/sss/1854/2/
EXAMPLE 4: Value bets
Before the flop - NL10 - Blinds: $0.05/0.10 - 9 Players
You are in early position with QQ
• Everybody before you folds.
• You raise to $0.30. You have $3.80 remaining.
• The player in the Small Blind calls.
Flop Ts9h3h - Active Players: 2 - Pot: $0.70
• Your opponent checks.
• You bet $0.50. You have $3.30 remaining.
• Your opponent calls.
Turn 5s - Active Players: 2 - Pot: $1.70
• Your opponent checks.
• You bet $1.20. You have $2.10 remaining.
• Your opponent calls.
River Kd - Active Players: 2 - Pot: $4.10
• Your opponent checks.
• You check.
Would you fold if opponent bet $2 instead of checking? Judging from the limping calls they could have QJ, giving them an OESD on the flop and turn.
