Hold'em table

Three-handed play makes Q8o playable enough to attack the blinds from the button; a small 2.5bb open applies pressure while keeping risk low if raised.

A3o is too weak to continue out of position against a button open, especially with the big blind still to act. Folding avoids a dominated, hard-to-play hand.

6s 2d is trash and cannot be defended profitably even getting decent odds against a button open.

T3 offsuit is too weak to open even from the button, so folding is the highest-EV option.

I hold AQo blind-versus-blind after the button folded, making this a clear value raise.

75 offsuit has very poor equity against a preflop raise, and calling 200 more out of position with a dominated hand is -EV. Folding preserves chips for better spots.

Opening from the button with suited ace Ad3d is a standard value/stealing raise in 3-handed play.

Facing only a min-raise to 200 in 3-handed play, Q9o is a cheap call from the SB with decent equity against the button's wide opening range. Folding is too tight given the small price, and 3-betting this hand is too weak.

97o is too weak to continue against a button raise and a small-blind call; folding saves the remaining big blind.

I flopped two pair (aces and nines) with Q9 on A95r, so I'm betting out for value against the preflop raiser's likely ace-x or overpair range while protecting my hand.

We hold top pair with a weak kicker in position against a donk bet, making a call the standard play to pot-control and keep in worse hands.

The turn queen gives me top two pair (queens and nines), which beats all one-pair hands including Ax. I bet around 75% of pot for value and to charge hands like T-J drawing to a straight.

The board is completely rainbow, leaving few natural semi-bluffs for the small blind's donk-flop and turn-barrel line. Our A3 has the worst possible kicker among top pairs with virtually no redraws.

On the button 3-handed, K-high is near the bottom of a wide opening range but has fold equity and position if called, so a standard 3x open is better than folding.

Pocket eights are ahead of a button open in three-handed play, so I 3-bet to 900 to build the pot and deny equity rather than flat out of position.

A2o is far too weak to continue against an open and a 3-bet, especially out of position.

K2o is dominated by nearly all of seat_2's 3-betting range; calling 600 into a 1300 pot needs ~32% equity that this hand rarely achieves, and 4-betting such a weak holding is far too risky.

Button open with suited connectors is standard; a 2.5x raise builds the pot in position and can take it down preflop.

Holding 5h 2h out of position against a button raise is a clear fold preflop.

K9o has enough equity against a wide button opening range to defend my big blind; calling only 150 into a 400 pot requires ~27% equity, which this hand clears, and folding would be too tight.

I have only king-high with a weak backdoor club draw on a paired, coordinated board, and I'm out of position against the preflop raiser. Checking keeps the pot small, realizes equity cheaply, and lets the button bluff into me; a lead bet here has little fold equity.

As the preflop raiser, I c-bet a paired flop with two overcards and a gutshot. A small bet can fold out weak hands while keeping the price reasonable when called.

I only have king-high with a backdoor club draw on a paired 6-7-7 board, facing a bet from the preflop raiser. With almost no equity or fold-equity, calling or bluff-raising loses chips long-term, so folding is correct.

Opening JTs on the button to 2.5x is standard GTO play for 3-handed 100bb poker.

Queen-two offsuit is dominated by any queen in the button's raising range and plays poorly out of position against a 2.5x open, so calling 200 more for weak equity is -EV.

K2o is too weak and poorly playable to continue out of position against a button open. Folding avoids dominated spots and unnecessary chips.
