Hold'em table

On the button three-handed, K3s is well within a standard open-raise range; I have position on both blinds and can win the pot with fold equity or play a cheap flop in position.

J5 offsuit is too weak to continue from the small blind against a button open; folding avoids a dominated, poorly connected hand out of position.

J6s is too weak to defend out of position against a 3x button open.

Jack-deuce offsuit is too weak to open from the button even three-handed, so folding avoids spewing chips.

In a blind-versus-blind spot after the button folded, 43s makes a solid hand to attack with initiative.

52s is one of the worst starting hands and is heavily dominated by a raising range; calling 200 to win 600 needs ~33% equity I don't have, and playing OOP postflop with no made-hand potential is -EV. Folding is clearly best.

76 offsuit is too weak to profitably open from the button even in 3-handed play.

Pocket nines heads-up against the big blind have strong equity (~60%+), so I raise for value and fold equity rather than just completing. A standard 3x open keeps the pot manageable while punishing weak BB hands.

Q7 offsuit is too weak to continue against a small-blind raise to 3bb after the button folds; folding avoids dominated, low-equity spots.

King-jack offsuit is a strong button hand three-handed; a standard 3bb open builds the pot with position and applies pressure on the blinds.

ATo has enough equity against a button open to continue, and calling 250 keeps the pot manageable out of position rather than bloating it with a light three-bet while the big blind is still to act.

Q5o has terrible playability out of position in a multiway pot; an easy fold.

I have second pair with an ace kicker on a coordinated board, so I check to pot-control out of position and let the preflop raiser define the action.

My K-J flopped the king-high straight, second only to A-J, so I bet for value while charging any two-club flush draws. A ~65% pot bet keeps worse made hands and draws in the pot.

I have top pair with an ace kicker on a coordinated board and only need about 28% equity to call this c-bet. Raising risks isolating myself against stronger queens and sets, so calling keeps worse hands and draws in.

I have second pair with an ace kicker on a coordinated board, so checking controls the pot and lets me react to the button's aggression.

My K-J makes the king-high straight (K-Q-J-T-9), the effective nuts on this turn since only another K-J can tie me. A large value bet targets flush draws, straight draws, two pair, and sets from a passive check-caller, and sets up a river shove.

Second pair with an ace kicker is ahead of enough bluffs and weaker barrels to continue. Calling keeps the pot manageable and lets me reassess on the river rather than raising a marginal made hand.

I have only a pair of tens on a board full of straights and flushes, so betting risks getting raised off a hand with some showdown value. Checking is free and lets me see what seat_1 does.

I hold K-Q-J-T-9 (K-J with the board), so I'm betting the river for value against the two pairs and sets that check-called the turn; their river check makes a flush or nut-straight trap less likely.

Pair of tens is a weak bluff-catcher on this K-Q-T-9 board after villain barreled every street; too many kings, queens, straights, and flushes beat me to call 2500.

T2 offsuit is too weak to open even from the button in a three-handed game, so folding avoids putting chips in with a dominated, disconnected hand.

Holding T4o in the small blind is too weak to complete or raise, even blind versus blind.

K2o is too weak of an offsuit hand to open profitably from the button even in a 3-handed game.

Heads-up after the button folds, A6s has solid equity against the BB. A small 3x raise builds the pot with position while keeping the range wide.

Button folded so this is heads-up, and K6o has enough equity in position against a wide small-blind open to call 200 into 400.

King-high with no pair or draw has some showdown value heads-up, and the opponent's flop check was a timeout rather than a clear tell, so checking realizes equity without bloating the pot.

Top pair on the turn heads up; betting about half pot extracts from worse aces and charges any flush or straight draws while keeping the pot manageable with a weak kicker.

King-high with no pair and no draw is too weak to call a turn bet on an ace-high board. Folding avoids putting more chips in with almost no equity.
