Hold'em table

Button open with A2o in a raked-free 3-handed game; a small raise takes the initiative and realizes position better than limping or folding.

K6o is too weak to defend out of position against a button raise and the big blind still to act.

J5 offsuit is too weak to profitably defend against a 2.5bb button raise out of position. Its poor playability and domination risk outweigh the favorable pot odds.

Ad6d is a strong suited ace on the button in 3-handed play; raising to 2bb is standard to steal the blinds or play in position.

T9 offsuit is a marginal defend from the small blind, where I will be out of position and the big blind can still raise. Folding avoids a low-realization call with a hand that often makes dominated pairs.

85s has enough suited equity and playability versus a small button open to defend the big blind for 100 into a 350 pot.

I have no pair, no draw, and no board connection on 7h-4h-Qd, so I check and realize my equity for free rather than bluff into the preflop raiser.

Check back with Ace-high and backdoor equity to control the pot size and realize equity on the turn.

Middle pair with a weak kicker has some showdown value but is too thin to bet into the preflop raiser on a coordinated turn. Checking controls the pot and avoids building a large pot out of position.

Check behind on the turn to take a free card with Ace-high and a gutshot straight draw, preserving pot control in position.

I have a weak pair of eights with a five kicker on a queen-king board. With no bet to call, checking to showdown is better than betting into a range that can easily be ahead.

Ace-high has some showdown value against missed draws after checking down all streets.

32 offsuit is too weak to open profitably against two blinds at 100bb depth. Folding avoids investing in a hand with poor equity and playability.

Jack-five offsuit is too weak to continue heads-up for a raise or a call; folding limits the loss to the small blind already posted.

23o is the worst starting hand and I am first to act; folding avoids putting chips in with no equity advantage.

K4o is a weak offsuit king that underperforms out of position against the big blind, making an easy fold.

K9o is well within the standard opening range from the button in 3-handed play. Opening for a min-raise applies pressure while maintaining pot control.

A2 suited is a good three-bet bluff against a button min-raise, with an ace blocker and nut-flush potential. Raising to 800 pressures both opponents and avoids a passive multiway pot out of position.

T3o is too weak to continue facing a 3-bet to 800; folding saves chips for better spots.

Fold K9o facing an 8bb 3-bet from the small blind as it is too weak to continue profitably.

Opening 5♠4♠ on the button can win the blinds immediately and gives this suited connector positional value when called. A 2.5bb raise applies pressure while keeping the investment modest.

QTo has enough equity and playability versus a 2.5x button open in three-handed to continue, and calling keeps the hand simpler than a light three-bet out of position.

Holding 82o multiway out of position against a raise and a call is an easy fold despite the pot odds.

Queen-ten has only overcards on a low disconnected flop, so checking keeps the pot small and realizes equity without bloating against the preflop raiser.

I have a pair, an open-ended straight draw, and a backdoor flush draw, so taking a free card in position preserves substantial equity. This low, connected board can favor the small blind's calling range, making a check preferable to risking a check-raise.

Queen-high with no pair or draw on 5-3-6-9; checking is free and avoids bloating the pot out of position.

My pair of fives has some showdown value alongside an open-ended straight draw. Checking behind preserves that equity without building a pot against better pairs or risking a check-raise.

Queen-high has little showdown value, but a river bluff into a paired board after two checks risks more than the small pot justifies. Checking realizes the free showdown.

Our pair of fives has showdown value against unpaired hands, but a river bet would mostly fold worse hands and get called by better ones. Checking realizes that value without risking extra chips.
