QQ should size preflop raises to build a pot while pricing out speculative hands. Against a single 99 caller, QQ wants to get as close to all-in preflop as reasonable. On low flops (8-high and below), QQ is in a strong position and should bet for value across multiple streets. On high flops (K or A), QQ should bet cautiously — the opponent's range likely includes some AK and AQ combinations that have connected.
99's Set Mining Math
For 99, the math is simple: flop a set 11.8% of the time and win a big pot, or miss and fold to aggression. The required stack-to-call ratio is at least 15:1 (some players use 20:1 for a margin of safety). With 100bb stacks and a 3bb open, 99 needs to expect winning at least 45-60bb when hitting a set — achievable against an overpair that will stack off.
