Hold'em table

Three-handed, the button opens very wide, and 67o has position postflop even though it's offsuit. A cheap min-raise pressures both blinds while risking little if called.

A7o plays poorly out of position facing a button open with the big blind left to act, making fold the standard play.

A8o is ahead of enough of a button min-raise range to continue, and 100 to win 350 is a good price. Calling keeps the hand and avoids bloating the pot out of position with a dominated ace.

I have ace-high with only a backdoor flush draw on a paired king flop, so there is no value in betting into the preflop raiser. Checking keeps the pot small and realizes my equity for free.

I flopped two pair (kings and sixes) on the K-K-6 board, so a small bet targets folds from unpaired hands and charges flush draws, while I can release if facing heavy aggression since Kx and pocket pairs 77+ outdraw me.

Ace-high with no pair and no draw on a paired king flop is too weak to continue against a flop bet. Folding avoids putting more chips in with little equity.

J4o is too weak to open-raise from the button even in 3-handed play.

J4 offsuit is too weak to continue out of position for another half-blind against the big blind.

86 offsuit is too weak to open even on the button in three-handed play, so folding avoids a dominated spot.

KQs is a strong suited broadway hand, especially 3-handed, and I have position on both blinds. A standard 3x button open builds the pot with value hands while retaining fold equity.

K2o is too weak to defend out of position against a 3bb button open with the big blind left to act.

Q5 offsuit is too weak to continue out of position against a button open; folding avoids a dominated, low-equity spot.

Open-raising from the button with a pocket pair to steal the blinds or play in position with set-mining value.

T6o is too weak to continue against a button open, especially with the big blind still to act. Folding avoids paying 1.5bb with a dominated, poorly connected hand.

Only 100 more to call into a 350 pot against a button min-raise; QTo has plenty of equity to defend the big blind profitably.

Top pair with a weak ten kicker out of position against the preflop raiser on a two-heart board; checking keeps the pot small, lets worse hands bluff, and avoids building a big pot where I'm dominated by AQ/KQ.

With an underpair to two broadway cards, checking back in position controls the pot size and realizes our showdown equity.

We have a weak pair and picked up a gutshot straight draw; checking behind controls the pot and takes a free card to see the river.

I hold top pair (queens with a T kicker) on a blank river, and seat_2's preflop-raise-then-check-check line is capped toward one-pair/air hands. A small value bet extracts from worse queens and lower pairs while staying cheap, and I can still fold if raised.

Our pair of threes is very weak on a board where any Ace or Six completes a straight, and any pair above threes beats us.

42 offsuit is too weak to open even on the button; folding avoids a negative-EV spot.

Heads-up vs the BB after the button folds, 73o has decent equity and a cheap min-raise generates fold equity; calling leaves me out of position with a weak hand, so applying pressure is the better EV line.

Getting 3 to 1 direct pot odds in position against a small blind min-raise, Q7o has sufficient equity to comfortably defend.

Heads-up vs the BB caller I hold bottom pair plus a spade flush draw on the monotone flop; a half-pot-ish semi-bluff folds out their many missed hands while I keep solid equity when called.

I completely missed the monotone flop with queen-high and no spade, facing a bet from the preflop raiser.
