Hold'em table

Pocket eights are strong enough to open-raise from the button for value and initiative in a three-handed pot.

2s6s offsuit is a weak hand facing a 3bb raise with another player still to act behind; not worth defending.

T4o is far too weak to defend the big blind against a 3x button raise; I would need ~31% equity and this hand rarely gets there even when it flops a ten. Folding is clearly optimal.

7-10 offsuit is too weak to open from the button in a 3-handed game; folding preserves chips.

Pocket sixes heads-up against the big blind is well ahead of a random range, so I raise for value and to build the pot while retaining position.

23 offsuit is too weak to continue against a raise, even heads-up. Folding avoids putting more chips in with a hand that has poor equity and no playability.

Ten-five offsuit is too weak to open even on the button three-handed, with little fold equity incentive and poor postflop playability.

Q7o is too weak to continue out of position against the big blind after the button folds; the extra 50 is not worth playing this hand.

A9o is a standard button open in three-handed play. Raising to 2.5bb takes the initiative and can fold out weaker hands before the flop.

5-9 offsuit is weak against a raise with two players left to act; folding preserves chips.

J4o is far too weak to defend the big blind against a 2.5bb button raise, especially out of position with a wide-but-dominated hand. Folding preserves chips for better spots.

Button raise with a playable suited-ish connector against two blinds; standard steal-sized open.

98 offsuit is far too weak to call a 2.5x button raise out of position, especially with the big blind still to act behind me. Folding is the clear highest-EV play.

KJo is strong enough to defend the big blind against a 2.5x button open, and calling 150 into 400 is a standard continue rather than folding a playable hand out of position.

King-high with no pair or draw on an ace-high flop against the preflop raiser has little value, so I check and keep the pot small.

C-bet the ace-high flop as a continuation bluff after preflop raise; opponent checked, likely weak range.

King-jack high missed this ace-high flop and has no draw, so calling a 300 flop bet is not profitable.

86 offsuit is too weak to open even three-handed from the button, and calling leaves me out of position against two players with a dominated hand. Folding costs nothing and preserves EV.

Heads-up versus the big blind, A5o is worth the extra half-blind to see a flop rather than folding an ace. Calling keeps the pot small with a weak offsuit ace.

Weak offsuit hand (9-3), no reason to raise; checking option in the big blind for free is best.

Bottom pair with an ace kicker is too weak to bet for value into the big blind, and a half-pot minimum bet mostly gets called by better. Checking controls the pot and keeps bluffs and weaker hands in.

I have 9-3 offsuit with no pair or draw on a K-T-5 board; checking is free and there's no reason to bluff into two opponents likely to have some equity.

I have trip fives with an ace kicker on a paired board, so I bet about three-quarters of the pot for value against king or ten hands that checked the flop.

9-high with no draw facing a bet on a paired board; not worth continuing.
