Hold'em table

7c8s is a weak hand out of position (button in a 3-player game, facing a raise). With no flush draw potential and poor kicker, folding minimizes losses against likely better holdings from the small and big blind positions.

T5 offsuit is a weak blind-versus-blind holding and does not justify continuing against the big blind.

JTs has sufficient button value to open in a three-handed game. A 2.5bb raise pressures the blinds while keeping the pot manageable.

6-9 offsuit is weak, facing a raise with two players still to act behind; not worth continuing from the small blind.

K5o is a weak hand out of position against a 2.5x raise from the button. Folding preserves chips and avoids playing a marginal hand against positional disadvantage.

Button with weak offsuit low connectors (5-6 offsuit) facing a raise from BB into a multiway pot; not worth continuing given poor equity and no position advantage against two live players.

A7s is a strong hand with good playability. With only two opponents (button folded) and in position as small blind, raising to 300 (3x the big blind) applies pressure while building the pot with a premium hand. The big blind will need to fold or commit more chips with a weaker range.

K2 offsuit is too weak to defend against a small-blind raise, especially out of position postflop.

J9 suited is a strong heads-up blind-versus-blind hand. Raising applies pressure and builds a pot with a playable equity advantage.

2d Ts is weak offsuit, facing a raise with button folded already; not worth defending here.

On the button, Q7 suited is a reasonable steal-raise against the blinds. Raising also gives initiative and can win the blinds outright.

Q7 offsuit facing a raise from the button with a call needed out of position and a BB left to act is not worth defending.

5-9o is a weak hand with no premium features. Against seat_2's raise to 250 from the button, folding preserves chips. Calling costs 150 more chips from my 9900 stack, but I'm out of position postflop with a marginal holding that is dominated by many hands in seat_2's raising range.

I'm on the button with K5 suited; raising to isolate and take advantage of position with a decent speculative hand.

Queen-Eight offsuit is a marginal hand facing a 3BB raise from the button. With weak hand strength, poor position (small blind), and no reads suggesting opponent weakness, folding preserves chips for stronger situations.

Defend the big blind against the button min-raise with suited ace-three. The price is low and this hand retains reasonable postflop playability.

Check to the preflop raiser with bottom pair and an ace kicker, keeping the pot manageable while retaining bluff-catching and improvement opportunities.

Top pair on a dry board; betting for value against a checking opponent while denying draws.

I have bottom pair with an ace kicker/blocker and sufficient equity to continue versus a single flop continuation bet. Calling keeps weaker hands and bluffs in while avoiding unnecessary variance.

Our pair of threes has limited value against the flop betting and calling range, which contains many kings and nines. Checking preserves showdown value and lets us potentially catch river bluffs.

I have two pair (Kings and Nines) with a strong kicker, so I bet for value on the turn.

We have two pair on a paired board and need only modest equity versus the turn sizing. Calling preserves value against bluffs and weaker pairs while avoiding a raise into stronger kings, nines, or boats.

We have only a weak pair on a paired board after calling substantial prior-street bets. Checking preserves showdown value and avoids turning it into an unnecessarily risky bluff.

I hold top pair kings plus the board pair of nines for a strong two pair, and villain has shown passive strength by checking the river after calling two streets, so I'll bet for value.

My pair of threes is a weak bluff-catcher against a consistent three-street line on this paired board. It is unlikely to beat enough value hands or bluffs to justify the river call.
