Hold'em table

K7o is a standard open from the button in 3-handed play, so I'm raising to 2.5bb to steal the blinds.

2-Jack offsuit is a weak hand from the small blind facing a raise to 250. The raise requires 200 more chips with unfavorable position and poor hand strength; folding preserves chips for better opportunities.

Getting 150 to close the action with A9o against a likely wide button open, so the pot odds justify a call despite being out of position.

I have ace-high with no pair on a paired board, and the preflop raiser likely has a strong range. Checking allows me to see a free turn card and avoid bloating the pot with a weak hand.

Top pair on a dry paired board that strongly favors the preflop raiser. A small c-bet gets value from worse kings, 3x hands and draws while keeping the pot controlled against better kickers.

A-high has decent equity against button's wide c-bet, and the pot odds are favorable enough to call and evaluate the turn.

I have only ace-high on a paired board and am out of position; checking controls the pot and lets me fold to further aggression.

Top pair with a weak kicker is likely still ahead of the big blind's flop-calling range of Tx, pairs and heart or straight draws. A bet of about half pot gets value and charges those draws while keeping the pot manageable.

Ace-high with no pair and only three outs to an ace; opponent has shown strength across preflop, flop, and turn, so the pot odds are insufficient to continue.

9-3 offsuit is one of the weakest starting hands in poker. Even from the button in a 3-player game, folding this hand is optimal against two opponents who have already committed chips to the pot.

Calling 50 more with suited low cards given 3:1 pot odds; folding forfeits the small blind and raising into a big blind who already invested 100 would risk too much with a weak hand.

J6o is marginal against a small-blind limp, so I'll take the free flop and keep position over the SB postflop.

With 6-high and no draw on an ace-high flop, checking preserves chips and avoids building a pot with a very weak hand.

The small blind limped and checked, so his range looks capped. A small half-pot stab with a gutshot to Broadway (KQ) can take it down often, and the Ace-high board favors my range.

I have 6-high with no pair or draw on an ace-high flop and only get 3:1, so folding to the bet is best.

8d2s is a very weak offsuit hand with poor playability, and calling 100 chips from the button is not worthwhile even with position. Folding avoids unnecessary risk in a marginal spot.

A9s is a strong hand blind-vs-blind after the button folds, so I'm raising to 3bb for value and initiative.

9-J offsuit is a weak holding facing a 3x raise from the small blind. With poor equity against a likely stronger range and no significant pot odds to justify the call, folding preserves chips for better spots.

J3o is below a sound button opening range in 3-handed play against two blinds, so folding is the low-variance choice.

5d8s is a weak starting hand with poor equity against a big blind raise. With only 50 chips already invested (small blind), folding is the mathematically sound play to minimize losses on a low-value hand.

4-9 offsuit is a weak hand with poor win probability from the button. Folding avoids investing chips in a marginal situation where I'd be out of position postflop against two opponents.

Completing the small blind with J9o, getting 3:1 immediate pot odds and keeping the pot small out of position.

With 42o in the big blind against a small-blind limp, checking sees a free flop. Raising this weak hand gains little and I'd play the pot out of position.

I have middle pair plus a flush draw on a monotone board; betting for value and protection.

The pot is 300 and I need to call 100, so I need about 25% equity. A gutshot to the wheel, a backdoor-style low flush with the 2d, and some pair outs justify a cheap call against a small bet.

I have two pair (jacks and nines) on a wet board with a possible flush. Betting for value and protection against draws is best, as checking would give a free card.

With a weak flush draw plus a wheel gutshot (about 12 outs), and deep stacks giving implied odds, calling 300 into a 1000 pot is a reasonable price. Raising is unnecessary on this monotone board.

I have two pair but the board is highly coordinated with possible flush and straight completions, so checking controls the pot and avoids getting raised by a stronger hand.

With 4-high I have no showdown value, and the villain gave up on the river after small barrels. My calls on a monotone diamond flop credibly represent a flush or straight, so a two-thirds-pot bluff should fold out enough marginal hands.

I have two pair (Jacks and nines) and am getting good pot odds (calling 650 into a 1650 pot). The opponent's line can include missed flush draws or weaker made hands like A-x/Q-x, so calling is profitable despite the coordinated board.

On the button in a 3-handed game, Jh7s is worth an open-raise to apply pressure to the blinds and take the initiative with position.

64s from the small blind facing a button 3x open, with the big blind still to act behind, is a weak and out-of-position spot. Folding is standard; a 3-bet bluff is possible but marginal.

4-2 offsuit is one of the weakest starting hands in poker. With an opponent's aggressive raise to 300 from the button and 200 more to call, folding is clearly the optimal play. The hand has minimal equity and poor playability postflop.
