Hold'em table

K6o on the button for 100 into 150 is a fine price; calling keeps the pot small and I have position postflop.

82o is a weak hand out of position in a 3-handed pot; folding the small blind is standard and cheap.

With 5s7d, a weak offsuit hand, checking is the best play since we can see a free flop from the big blind and have no reason to fold or raise.

I have a weak king-high with no pair on a dry flop. Checking keeps the pot small and lets me see a free turn card rather than betting into the big blind who could have connected.

I have 5-high with no draw on a dry board, so checking is the safest play to avoid bloating the pot with a hopeless hand.

I have king-high with no pair and no draw on a dry board; checking keeps the pot small and I can fold to a bet.

I have bottom pair with a weak kicker on a relatively dry board. The pot is small and my opponent has shown no aggression, so checking to try to reach showdown cheaply is best.

K-high has showdown value against missed draws, and the opponent has checked every street, so checking realizes equity without risking chips as a bluff into a possible pair or ace-high.

AJo is strong 3-handed, especially with position on both blinds. A standard 3x raise builds the pot with a hand that plays well postflop.

A5o is a marginal hand out of position against a button raise; folding preserves chips for better spots.

9-3 offsuit is too weak to defend out of position against a button raise, especially with the small blind already folded.

K9o on the button in a 3-handed game is strong enough to open-raise, aiming to steal the blinds or build a pot with position.

Q7o is a weak offsuit hand out of position, and calling a 2.5x button raise with it is likely -EV. Folding is the standard play.

Q2o is far too weak to call a 2.5x raise out of position heads-up; folding maximizes EV.

K2o is too weak to continue from the button against two blinds, even with position. Folding avoids investing chips with a dominated, low-equity hand.

6d3c is the worst hand in 3-max; folding the SB to a likely BB raise is correct.

64s is a weak hand out of position against two players; folding is the standard play.

J7o has ~48% equity against a random hand, and calling 50 to win 150 gives 3:1 pot odds, making it a profitable call. Folding would forfeit the small blind, and raising risks too much with a weak hand out of position.

KTo has decent equity against a small blind limper, and raising in position can take the pot down or isolate a weak range.

I am on the button with Jh Qc, a decent hand in 3-handed play. Raising puts pressure on the blinds and builds the pot with a hand that can flop well.

J9o is too weak to call a button raise from the small blind with the big blind still to act; folding preserves chips.

9c6c is weak against a 2.5x raise from the button with the small blind already folded; calling out of position with a marginal suited connector gives poor equity.
