Hold'em table

54s is a standard suited connector open from the button in 3-handed play.

K2 offsuit is far too weak to call a 2.25x raise even at an SB discount, with the big blind still behind and poor postflop position. Folding is clearly best.

J8s has enough equity and playability against a wide button open to call 1.25bb from the big blind rather than fold or inflate the pot out of position.

Jack-high with no pair and no draw on a paired flop is too weak to bet out of position, so I check and realize equity for free.

Paired dry boards strongly favor the preflop raiser's range; a one-third pot continuation bet exerts good pressure against BB floats and missed overcards.

Jack-high with no pair, draw, or backdoor equity is too weak to continue against a flop bet on a paired board. Folding avoids putting more chips in with little chance to improve.

A9s is a strong 3-handed button open with position and nut-flush potential; a standard 3x raise builds the pot and applies pressure on the blinds.

Ten-deuce offsuit is too weak to continue against a button open, so folding the small blind is the clear choice.

J9 offsuit does not realize equity well out of position against a 3bb button open, making fold the standard play.

J9o is playable as a button open in three-handed play; a small raise takes the initiative and can fold out worse hands before the flop.

Q5o is too weak to defend out of position against a button raise with the big blind still to act behind us.

4s6c offsuit is far too weak to defend the big blind against a 2.5x button raise; I'm dominated too often and calling 150 more with no fold equity is -EV.

Opening K8o from the button in 3-handed play is a standard profitable steal attempt.

2d4d is far too weak to call 150 more out of position against a button raise with the big blind still to act. Folding is clearly the highest-EV play here.

Pocket threes are ahead of a wide button open often enough, and calling 100 into 350 is a standard defend to set-mine and realize equity.

Pocket threes are an underpair on Q-9-4, so I check to the preflop raiser rather than build a pot out of position with a weak made hand.

Checking back to realize equity with King-high and control the pot on a Q-high flop.

Pocket threes are an underpair to the queen and king with no draw, so a turn bet mostly gets called by better and folds out worse. Checking keeps the pot small and preserves a little showdown value.

Turn gave us top pair; betting half-pot targets value from Queens, weak pairs, and charges heart or straight draws.

Pocket threes are an underpair on a king-queen board and have poor equity against a turn bet after the flop checked through. Folding avoids paying off a likely made hand.

Button raise with K7o for position and fold equity; a 3x open applies pressure on limped pot, and I can retreat cheaply if attacked.

A8s is strong enough to 3-bet a button open in three-handed play, and raising applies pressure while I am still out of position. A 10bb size is a standard squeeze against the 3bb open.

Facing an open and a 3-bet out of the blinds, QJo is dominated and playing out of position is unprofitable.

K7s needs roughly 33% equity to call 700 into 1400, and it rarely gets there against a strong SB 3-bet range — often dominated when a king flops. With no reads and stacks resetting each hand, folding is the highest-EV play.

A7o is a standard button open in three-handed play; a 2.5bb raise takes the initiative cheaply and can fold out worse hands.

Calling 200 chips from the small blind with pocket fours to set mine given 100bb effective stacks against the button open.

A6s in the big blind against a 2.5x open is close, but suited ace equity and cheap 150 to call makes defending fine in position... actually out of position, but pot odds justify seeing a flop.

I hold an underpair on a broadway-heavy flop in a multiway pot out of position, making a standard check the only prudent play.

I only have ace-high with a backdoor diamond draw on KJ3; with the preflop raiser still to act, checking back keeps the pot small and may give me a free card.

Ace-high with no pair or draw has some showdown value multiway, and both opponents checked, so taking a free card is better than bluffing into two players.

I have a weak underpair on a board with multiple overcards and two opponents, making a check the clear play.

A6o missed the J-3-K-9 board entirely and everyone checked flop; with no to-call, checking is free and I can fold to a bet.

Ace-high has no pair or draw on Jh-3c-Kc-9h, and both opponents checked the turn. Checking keeps the pot small and realizes whatever showdown value I have.

I have a weak pocket pair on a coordinated board with two opponents still in the hand. Checking to realize any possible showdown value is best.

All players checked every street, so A-high may well be best; a small river bet risks little to win the 750 pot against checked-down weak hands.

Bottom pair with an ace kicker has enough showdown value against a delayed river stab after two checked streets, and the price is only 450 into 1200.

With pocket fours on a high board facing a river bet and call from both opponents, my fourth pair has virtually zero equity.
