Hold'em table

67 offsuit is too weak to open even from the button; folding avoids building a pot with a hand that is often dominated.

A7s from SB heads-up vs BB is strong; raising for value and fold equity.

A8o is a standard defense against a small blind open when getting 2:1 pot odds in position.

I missed the K-high flop with A7s; checking back keeps the pot small and avoids building it out of position with little equity.

I have Ace-high with backdoor nut flush equity on a paired king board; checking back keeps the pot controlled in position.

Both checked the flop, so I'll stab at the pot with ace-high; a small turn bet has good fold equity and I can fold if raised.

Holding just Ace-high with no substantial draws on a paired board, calling a half-pot delayed turn bet offers insufficient equity and poor playability on the river.

J4 offsuit is a weak hand out of position against two players; folding is clearly best.

J4o is too weak to complete or raise blind vs blind out of position.

86o is too weak to open profitably from the button in 3-handed play.

95o is too weak to continue out of position for another 50 after the button folded; folding avoids a poorly playable pot.

KQs is a premium suited broadway on the button, so I open-raise to 3bb to build the pot and take the initiative rather than flat the big blind.

K2s offsuit is far too weak to call 3bb out of position against a raise; folding is clearly best.

Q5o has weak playability and low equity out of position facing a 3x button open, making it an easy fold.

T6o is too weak to complete or raise from the small blind out of position against the big blind.

42 offsuit is far too weak to open or defend, even from the button in a 3-handed game.

73 offsuit is too weak to continue out of position against the big blind after the button folds. Folding saves the extra half-blind rather than playing a dominated hand.
