Hold'em table

K5s is playable from the button in three-handed, so I open to 2.5bb rather than limp or fold.

AT offsuit is strong enough to 3-bet against a button open in a 3-handed game; raising builds the pot with a hand that plays well heads-up.

J9 offsuit is far too weak to call a 3-bet for 600 more out of position; folding loses only the blind and preserves chips for better spots.

K5s is too weak to continue against a 3-bet; it is often dominated and does not justify calling 450 or 4-bet bluffing.

43o is a weak hand not worth playing from the button facing a raise-sized pot in a 3-handed game.

J6s is a standard open-raise from the button in 3-max with positional advantage; raising to 3x applies pressure on both blinds and can win the pot immediately or play a favorable postflop position.

JTs is strong enough to 3-bet the button open from the small blind, taking the initiative and denying the big blind a cheap flop.

K6 offsuit facing a raise and a big 3-bet is not worth continuing; fold to avoid committing chips with a weak hand.

J6s is far too weak to call a 3-bet facing 600 more into a small pot; seat_1's raise to 900 signals a strong range and my dominated suited jack has poor equity and reverse implied odds.

26 offsuit is too weak to call or raise from the button against two live blinds, so folding preserves chips.

Heads-up pot after button folds; A2o plays fine as a steal-raise against a single big blind.

Pocket queens are a premium hand and I'm out of position against the SB raiser, so I 3-bet to build the pot and define my hand. A raise to 750 (3x) applies pressure while keeping the pot manageable if I get 4-bet.

A2 offsuit facing a 3-bet to 750 out of position isn't worth continuing; folding preserves chips.

Suited connector on the button, raising to isolate and take initiative against the blinds.

J9s has decent playability and I only need to call 250 into a 450 pot, giving good implied odds to flop a strong hand against the button's raise.

J6 offsuit is too weak to continue against a button raise and a small-blind call; folding avoids putting more chips in with a dominated, unconnected hand.

I have only J-high on a paired board with no bet facing me, so checking is free and keeps the pot small; I can fold cheaply if seat_2 bets, since my hand rarely improves enough to continue.

I have middle pair with a decent kicker on a paired, dry board; betting for value and protection against a checking opponent.

I hold jack-high with no pair or draw on a paired board, and seat_2 has shown aggression with a preflop raise plus a flop bet. Calling 350 with essentially no equity is a losing play, so folding is correct.

King-three offsuit is far too weak to play from the button in a 3-handed game with no limpers; folding preserves chips for better spots.

T6o is too weak to complete from the small blind out of position against the big blind, so folding the extra 50 is the higher-EV play.
