Hold'em table

K5o is too weak to open profitably from the button even in 3-handed play without antes.

Q4 offsuit is too weak to complete or raise from the small blind out of position against the big blind, so folding saves the extra 50 chips.

A6o is playable as a button open in three-handed play; a small raise takes the initiative and avoids a weak multiway call.

King-Jack offsuit has enough equity to see a flop cheaply against a 2.5x button open, especially with dead money already in the pot from both blinds.

Holding an unsuited and weak 85o out of position against a button raise and small blind call is a clear fold despite favorable pot odds.

With K-high on an A-high flop heads-up, I have little fold equity and can't call a bet profitably. Checking keeps the pot cheap and lets me see a free turn with backdoor potential.

I flopped top two pair on a dry board and the opponent checked, so I bet about two-thirds pot for value and protection.

I hold K-high with no draws on an Ace-high flop against the preflop raiser's continuation bet, so my hand has almost no showdown value. Calling 400 into 1000 with king-high is unprofitable, so folding is the cheapest line.

T6 offsuit is too weak to limp or steal with even on the button in a 3-handed pot; it flops poorly and is often dominated, so folding preserves chips for better spots.

In a blind versus blind spot after the button folds, Q9o is ahead of the big blind's random holding and makes a solid standard open raise.

69o is too weak to continue against a small-blind raise, and calling out of position would leave me dominated too often.

76 offsuit is too weak to open from the button even in 3-handed play.

Button folded, so this is heads-up versus the big blind. A small raise with ace-high takes the initiative and can win the pot immediately, while keeping the price reasonable if called.

Q8o is playable as a button open in three-handed; a small raise takes the initiative and can fold out worse hands.

98o offsuit out of position against a button raise with the big blind still to act is a standard fold; the hand makes too many second-best pairs and realizes equity poorly OOP, so the 3:1 price isn't enough to continue.

Holding 62 offsuit in the big blind against an open raise is an easy fold with virtually no playability out of position.

K5s is a standard button open three-handed with fold equity and decent playability; raising to 3x builds a pot I can take down postflop or win preflop from the blinds.

T6s is too weak to defend from the small blind against a 3bb button open with the big blind still to act.

73s is too weak to continue out of position against a button open; raw pot odds are close but realized equity is poor.
