Hold'em table

J8o is playable as a button open in three-handed poker, so I raise to 2.5bb rather than flat-calling the big blind.

Queen-two offsuit is far too weak to defend the small blind against a 2.5x button raise, with no fold equity or postflop playability. Folding saves 200 chips with a dominated, disconnected hand out of position.

Holding premium AKo in the big blind against a button open, raising for value and initiative to 10bb.

J8o is too weak to continue against a 10bb 3-bet; calling needs too much equity and a reraise would be a pure bluff with a dominated hand.

Ace-king offsuit is a premium hand and I'm on the button 3-handed, so I open with a standard 3x raise to build the pot and apply pressure while retaining position postflop.

Folding 75 offsuit from the small blind against a 3bb open.

QJo has enough equity against a button open to continue, and calling 200 into 450 is better than folding or bloating the pot out of position with a 3-bet.

Queen-high with no pair and no draw on a king-high board is too weak to bet out of position against the preflop raiser. Checking is free and keeps the pot small.

I hold top pair top kicker (A-K on K-8-6) after raising preflop and the big blind checked to me. Betting around 70% of the pot extracts value from weaker kings and mid pairs while charging spade and straight draws.

Queen-high with no pair and no draw on Ks-8s-6c is too weak to continue against a flop bet. Folding preserves chips for better spots.

95s is too weak to open profitably from the button even in a 3-handed game.

82s is too weak to play out of position for a raise, and completing leaves me first to act postflop with little showdown value. Folding the extra 50 is the higher-EV line.

54 offsuit is too weak to open from the button for a full big blind; folding preserves the stack for better hands.

43 offsuit is one of the worst hands; folding from the SB for 50 more chips is clearly best heads-up against the BB.

K7s is a standard button open in a 3-handed game; raising to 3bb applies pressure on both blinds and lets me play the pot in position when called.

96o is far too weak to defend out of position against a button raise.

A3o is too weak to continue out of position against a button 3x open: the ace is often dominated and the hand plays poorly postflop. Folding preserves chips rather than calling with a dominated offsuit ace.

Open-raising with an Ace on the button in 3-handed play is a standard value/steal opportunity.

K3s is too weak to continue from the small blind against a button raise; the king is often dominated and the hand plays poorly if the big blind comes along.

K7 offsuit out of position against a button raise is dominated too often and plays poorly postflop; folding and saving 120 chips is the highest-EV play.
