Hold'em table

Opening K9o from the button in 3-handed play is standard to put pressure on the blinds and utilize positional advantage.

2♣5♦ is too weak to defend out of position against a button raise, especially with the big blind still to act.

A8o has decent equity against a wide button opening range, and calling 125 into a 375 pot gives good pot odds while keeping the pot small with a hand that plays poorly 3-bet.

I missed the flop with just ace-high against a preflop raiser, so checking is best; I can fold cheaply to a bet rather than invest more with a weak hand.

Check back with King-high to control the pot size and realize equity on later streets without facing a check-raise.

I flopped/turned top pair with the ace after checking back the flop; the preflop raiser showed weakness by checking, so a half-pot bet charges draws and worse aces while keeping the pot manageable.

I have king-high with no draw on a 3-7-J-5 board, facing a turn bet. Folding is clear.

KJo is a strong hand to open from the button in a three-handed game. A 2.5× big-blind raise applies pressure while keeping the pot manageable.

J6 offsuit is far too weak to defend from the small blind against a 2.5x button raise; folding avoids playing a dominated hand out of position.

75 offsuit is too weak to defend against a button open, even getting reasonable pot odds from the big blind.

King-eight suited is a profitable steal from the button 3-handed; a standard 2.5x open applies pressure and can win the blinds or build a pot with position.

Holding pocket tens in the small blind against a button open is a clear value 3-bet to build the pot and take the initiative out of position.

Q5 offsuit is too weak to continue against the small blind’s large 3-bet, especially with the button still to act.

K8s is too weak to call a 3-bet out of position against the original raiser; folding loses only 750 more and preserves chips for better spots.

Nine-three suited is too weak to open profitably even from the button in 3-handed play.

K4 suited is strong enough to complete for the additional 50 chips heads-up, though raising would build a pot out of position with a marginal hand.

J5o is marginal, but I'm in position as the aggressor against a limper; a small iso-raise to 300 can take the pot preflop or build a cheap pot when called.

K4 suited has enough equity and postflop playability to defend against the isolation raise, especially with the favorable pot odds. I’ll avoid inflating the pot out of position.

With only king-high and no meaningful immediate draw, checking out of position is preferable to bluffing into the preflop raiser.

K-high has some showdown value, but this board offers no meaningful draw to support a turn bluff. I’ll take the free card after the flop checked through.

Opponent called a raise then checked twice, suggesting weakness; a half-pot stab with J-high can take the 600-chip pot, and I can fold if raised.

The small turn bet after the flop checked through could be a stab, and the pot odds make king-high a reasonable bluff-catcher. I have no strong draw, but can still be ahead of missed or weaker hands.

With only king-high and no heart blocker, a river bluff is unlikely to fold out enough of the opponent’s continuing range. Checking preserves a chance to win against missed draws or a checked-back bluff.

I hold pair of jacks (Jc + board Jh) on a three-heart board; betting gets folds from worse and only loses to queens or a flush. Seat_2's river check suggests a showdown, so I take the free check.

JJ is a strong button hand three-handed; raise to 2.5 big blinds for value and to build the pot while applying pressure to the blinds.

Pocket fours are a set-mining hand; calling 200 to see a flop with implied odds against the button's 2.5x open is standard, and folding or 3-betting OOP is worse.

97 offsuit plays poorly out of position multiway despite getting 4 to 1 pot odds.

I hold only a weak club flush draw (4c) with no showdown value on Ac-8c-7s against the preflop raiser's range. Checking realizes my ~35% equity cheaply, keeps the pot small out of position, and lets me profitably call a reasonable c-bet with nine outs.

JJ has useful showdown value, but the ace-high, connected board favors the caller’s range. I’ll take a free card and avoid inflating the pot.

My pocket fours only make a low pair on this A-high board with no draw worth betting; checking back and reassessing is best, and I can fold cheaply to a bet.

My jacks retain showdown value, but the ace-high board and new spade draw make a turn bet unlikely to get called by many worse hands. I’ll take the free river after the checks.

My pair of fours is a weak bluff-catcher on a board with an ace and three spades; betting only gets called by better hands, so I check and plan to fold to meaningful river aggression.

My pocket jacks may be ahead of missed draws and smaller pairs, but the ace and three-spade board make a river value bet risky. I’ll take the free showdown rather than get called mainly by better hands.

73o is well outside any reasonable small blind opening or completing range, so folding is clearly the highest EV play.
