Hold'em table

46o is too weak to open from the button for a full big blind, so folding preserves chips.

JTs is a strong suited connector heads-up from the SB; raising to 300 builds the pot with position and applies pressure to the BB.

8-2 offsuit is a trash hand facing a raise; easy fold even though only facing 200 more.

Ace-jack suited is a strong button hand; I raise for value and to build the pot while retaining position. A standard 3x open applies pressure without overcommitting.

T5s is weak facing a 3bb raise from the button with a call still needed from BB; not worth continuing out of position.

46s is too weak to continue out of position against a button open; the price is not good enough to realize this hand.

5c8c offsuit is weak from the button facing a raise-sized call; folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind with Ace-Ten offsuit. A raise to 300 builds the pot and applies pressure before the flop.

84s is far too weak to call a 3x raise needing 33% equity, and 3-betting this hand out of position against an aggressor just builds a big pot with a marginal hand.

A8o is a standard button open in three-handed play; a 2.5bb raise takes the initiative and folds out worse hands.

QJo is marginal but the pot odds are decent facing only a 2.5x open in 3-max; I'll defend from the SB and see a flop, folding if it turns bad.

5-9 offsuit is a weak hand facing a raise and a call; folding is correct here.

I flopped top pair with a strong kicker against a preflop raiser; checking induces a bet so I can raise or call profitably rather than defining my hand first on a flush-draw board.

I completely missed this dry flop but have the betting lead and position, so a small c-bet can fold out worse ace-high and weak hands that checked to me.

I hold top pair (jacks with a queen kicker) plus a backdoor flush draw, and the 200 bet into an 800 pot is cheap. Calling keeps the pot small while protecting against overpairs or better jacks.

I have second pair (jacks) plus a heart flush draw and queen overcard outs, but the ace on the turn favors the preflop raiser's range. Checking keeps the pot manageable out of position while preserving my ~14 outs, and I can profitably call a reasonable bet if one comes.

Top pair with a weak kicker has showdown value, but the ace is a scare card that folds out worse hands and invites raises from better aces. Checking controls the pot after the opponent checks.

I only hold second-pair jacks on an A-K-high board with three hearts, and seat_1's preflop raise plus flop bet strongly suggests an ace, king, or flush draw that got there. Checking back is the only way to reach showdown cheaply; betting or bluffing loses to nearly all of their value range.

I have top pair of aces with showdown value, but a river bet is called mostly by better hands and chops, so checking is best.

2-7 offsuit is the worst starting hand in hold'em; folding from the button costs nothing and preserves chips for better spots.

T9 suited is a strong hand heads-up against the big blind after the button folded; raising builds the pot and applies pressure.

AKo is a premium hand heads-up against a small-blind open, so I 3-bet to 900 for value and fold equity rather than flat.

Q3 offsuit is a weak hand out of position value with no fold equity gained from button here; folding is standard.

84o is too weak to continue out of position for 50 more against the big blind.
