Hold'em table

9-3 offsuit is a weak hand not worth playing from the button facing a raise-sized call; folding preserves chips.

5-2 offsuit is the weakest hand in hold'em and I'm on the button facing a raise-free limped pot; folding loses nothing and preserves chips for better spots.

97o is too weak to continue out of position for another half-blind against the big blind after the button folded.

KTo is a standard button open in three-handed play; a 2.5x raise takes the initiative and can fold out weaker hands.

J3 offsuit is a very weak hand facing a 2.5x button raise out of position; folding is clearly best.

7-3 offsuit is a trash hand on the button facing a raise-worthy pot; no reason to invest chips preflop.

Heads-up against only the big blind, 78o needs just 25% equity to complete the 50-chip call and has roughly 55% against a random hand, so limping is clearly profitable.

A6o is playable but not strong enough to raise for value heads-up against a completed small blind. Checking keeps the pot small and sees a flop for free.

I hold second pair (7s) on a J72hh board in a tiny 2bb heads-up pot. Checking keeps the pot small with a marginal hand and lets me reassess on the turn without facing a raise.

Limped pot with ace-high and no draw; checking is free and preserves showdown value rather than bluffing into the small blind's check.

I have a free check with a pair of 7s plus a spade flush draw and gutshot on this scary board; realizing equity cheaply in a tiny 200-chip pot is better than bloating it with a marginal semi-bluff.

Ace-high with no pair or draw has some showdown value in a tiny pot after two checks, so there is no need to turn it into a bluff.

I only hold a pair of sevens with a weak kicker on a board full of J/T/Q, so betting has little fold equity and risks value to stronger hands. Checking back for a cheap showdown is best.

Ace-high has some showdown value against a passive opponent who checked every street, and the pot is only 2bb, so checking is better than turning a potentially best hand into a bluff.

King-high suited on the button in a 3-handed game is a clear open; I'll raise for position and fold equity.

8h3h is too weak to continue against a button open, especially out of position with the big blind still to act. Folding saves chips for better spots.

K3 offsuit is too weak to open from the button even three-handed; folding avoids a dominated, poorly connected hand.

Heads-up after button folds; J9o is a reasonable hand to raise for value/fold equity against the big blind.

A4s has decent equity heads-up against a 2.5x raise from the small blind; calling 150 into a 350 pot with position and suited ace potential is profitable.

I have top pair with a decent kicker on a dry board; betting for value and to protect against draws.

I have a gutshot (any 6 makes 4-5-6-7), an ace overcard, and a backdoor flush draw, so calling 300 into an 800 pot is cheap with decent equity. Seat_1's flop bet is likely a standard continuation bet after the preflop raise.

Top pair with decent kicker on a somewhat wet board; betting for value and protection against flush draws.

I only hold bottom pair (4s) with a gutshot to a 6, roughly 14% equity with one card to come, which is far short of the ~22% needed to call 700 into the pot. Seat_1's triple-barrel aggression (preflop raise, flop bet, turn bet) strongly suggests a jack or overpair, so folding saves chips.
