Hold'em table

74o is too weak to open from the button in 3-handed play at 100bb, so folding is standard.

A7 suited is strong enough to raise against the big blind after the button folds. Raising to 300 builds the pot while retaining room to play postflop.

J4 offsuit is too weak to defend against a small-blind raise in this heads-up pot.

Seven-five suited is playable from the button in a three-handed game. A 2.5 big blind open gives me initiative while keeping the pot manageable.

J2 offsuit is too weak to defend from the small blind against an open, especially with the big blind still behind.

Getting 150 to win 400 (27% equity needed) against a button open in 3-handed play, Q7o has enough equity and playability to defend by calling.

Top pair with a weak kicker on a wet board, out of position against the button's range; checking controls the pot and lets me check-call against bluffs and draws.

A small continuation bet can fold out some of the big blind’s missed hands at a low cost. If called, this weak hand can usually give up unless the turn improves it.

Top pair with a weak kicker on a wet board facing a small 1/3-pot c-bet; calling keeps the button's bluffs in and controls the pot size. At 180 into 730, the price is great.

Top two pair is strong, but the spade flush just completed. A medium lead gets value from Qx, Tx and single-spade draws while keeping the pot controlled against made flushes.

Bottom pair with no spade has little chance to improve against a turn lead on a three-spade board. Calling is unlikely to be profitable.

T4 offsuit is too weak to enter with from the button in this configuration.

92o is one of the weakest hands to play out of position from the small blind against the big blind, so folding is the standard play here.

A5o on the button in 3-handed play is a clear open-raise; 2.5x puts pressure on the blinds with an ace blocker and wheel potential.

9-6 offsuit is too weak to defend from the small blind against a raise with the big blind still to act.

T5 offsuit is weak but has sufficient equity versus a likely wide button opening at this price, and calling preserves the big blind's pot odds.

Checking preserves pot control with little showdown value while allowing the preflop raiser to continuation bet.

Paired, dry board favors the preflop raiser, so a small c-bet with ace-high works well as a bet for both fold equity and thin value. Some weaker hands may fold.

This board gives me only five-high with no meaningful draw, and calling the continuation bet is not profitable.

T9 offsuit is strong enough to open on the button three-handed. A 2.5-big-blind raise applies pressure while keeping the pot manageable.

J5 suited is too weak to defend profitably against a button open in this stack configuration.

44 in the big blind facing a 2.5x button open, getting 150 to win 400, is an easy call for set mining and playability with deep stacks. A 3-bet would turn a hand that plays fine postflop into a bluff.

Small pair on an ace-high two-tone board, out of position against the button raiser; checking controls the pot, and I can decide facing a bet.

A small flop bet gets value from weaker pairs and draws while denying free cards. It keeps the pot manageable when called by an ace.

Small c-bet gives good pot odds (~21%). The pocket 4s have some showdown value against a wide button range on this ace-high board, so calling beats folding.

Pocket 4s on an A-T-3-8 board with two flush draws are a weak showdown hand facing a button c-bettor. Checking controls the pot size, and I can decide on the river based on the turn action.

Middle pair has showdown value, but worse hands may fold while aces and stronger tens continue. Checking controls the pot and keeps weaker hands in.

Our 44 has marginal showdown value against busted club draws in the button's turn check-back range. A bluff is unlikely to fold out the many Ax hands, so we check.

Middle pair has showdown value, but a river bet is unlikely to get called by many worse hands on this board. Checking also lets missed club draws reach showdown.

Q8 suited is a profitable button opening hand three-handed, with positional advantage and good playability. I raise to 2.5bb to pressure the blinds while keeping the pot manageable.

Against a wide 3-handed button open, 33 plays well as a 3-bet from the small blind, taking the initiative and folding out the big blind; calling out of position with a small pair is marginal.

6-2 offsuit is too weak to continue against a 10-big-blind three-bet, especially with the original raiser still to act.

Q8 suited is too weak to profitably continue against a substantial small-blind 3-bet, despite position.
