Hold'em table

K2 offsuit is too weak to open profitably on the button in this short-handed spot, especially with a dominated kicker risk.

Button folded, so this is effectively a heads-up SB vs BB spot. T8o has enough equity to raise for fold equity and to take initiative, while a small raise keeps the risk controlled.

Q7o is a weak hand with poor equity against a raise from the small blind. Folding preserves chips and avoids playing a marginal hand out of position.

Q4o is a weak offsuit hand with poor playability, and calling 100 into a small pot with two opponents still to act is not profitable enough. Folding preserves chips for better spots.

2-10o is a weak hand in the small blind facing a big blind. With seat_2 folded and seat_1 (big blind) not having raised, folding preserves chips and avoids playing a poor hand out of position postflop.

Q2o is a weak hand in early position (button with only two other players). Folding preserves chips for better opportunities rather than calling with poor equity against the blinds.

Complete the small blind with 7-8 offsuit heads-up and realize equity cheaply against the big blind.

With J3 offsuit in the big blind and no call required, checking is best to see a free flop rather than raising a weak hand.

This board favors the big blind's range, while 7-8 has little immediate equity or draw potential. Checking preserves the pot and allows us to react to their action.

With J-high and no pair or strong draw on K-Q-4, checking back controls the pot and takes a free card.

We have an open-ended straight draw on a coordinated board and can profitably apply pressure after both players checked. A modest turn bet can fold out weak hands while retaining strong implied odds when called.

9-2 offsuit is a very weak button holding and does not justify entering even for a minimum raise structure.

Heads-up against the big blind with Ace-high, raising applies pressure and can take down the pot preflop; if called, I can reassess on the flop.

With 3c9c (weak unsuited), facing a raise to 250 from seat_2, folding is correct. This hand has poor equity and is easily dominated in a heads-up pot against a raiser.

Q6o is a marginal but playable button open in 3-handed; raising applies pressure and takes initiative with position.

Ace-Ten is a strong hand that benefits from aggressive play preflop. Seat 2's raise to 250 from the button can contain many hands; a significant 3-bet to 800 applies pressure and defines our hand strength while leveraging position advantage. This build-pot sizing should narrow the field and extract value.

K8 suited is too weak to continue profitably versus a substantial small-blind squeeze after the button opened, especially out of position.

Qs6d is too weak to continue against a small-blind 3-bet, especially with poor playability and domination risk. Folding avoids investing more chips with a marginal offsuit hand out of position postflop.

Jack-Eight offsuit is a weak holding from the button in 3-handed play. Folding preserves chips and avoids a difficult postflop situation against two opponents who have already committed chips.

J9 offsuit is a playable blind-versus-blind hand and benefits from taking the initiative. I raise to apply pressure and retain equity when called.

Q5s has enough equity to defend the big blind against a small-blind open, especially with position after the flop; calling keeps the pot manageable while avoiding a marginal 3-bet.

I have a pair of nines with a jack kicker and a gutshot straight draw. A moderate continuation bet protects equity and gets value from weaker pairs and draws.
