Hold'em table

Seven-three offsuit is too weak to open profitably from the button without evidence that the blinds overfold. Folding avoids investing in a hand with poor playability.

72o is the worst offsuit hand and plays poorly heads-up out of position; folding avoids putting more chips in with almost no playability.

K4o is too weak to open from the button against two live blinds; folding avoids a dominated, low-playability hand.

Blind vs blind with T8o is a standard open from the SB. A 3x raise takes initiative and puts pressure on the big blind.

Q8 offsuit is strong enough to defend against a typical small-blind opening range at 2-to-1 pot odds. Calling preserves positional advantage postflop without inflating the pot with a marginal hand.

The ace-high, dry board favors my preflop raising range, so a small one-third-pot c-bet (200 into 600) can take it down. My hand has little showdown value and a backdoor diamond draw for equity if called.}

Queen-high has no meaningful draw on this ace-high flop. Despite the small bet, our weak equity and poor prospects against continued aggression make folding preferable.

J3 offsill is too weak to open profitably from the button in 3-handed play with 100bb stacks against two blinds, so I fold.

Completing costs only 50 chips into a 150-chip pot, making 97 offsuit a reasonable blind-versus-blind limp. This keeps the pot small while out of position with a marginal but playable hand.

A2s is too weak to raise for value heads-up against the limping small blind, and checking is free, so I take the flop.

Bottom pair has showdown value and backdoor straight and flush potential, but betting would often fold out worse hands and get called by better. Checking keeps the pot small out of position and lets us reassess against a bet.

Ace-high with no pair and no real draw has little value in a small pot after the small blind checks. Checking keeps the pot small and realizes my free card.

Our sevens have some showdown value, but betting is unlikely to get called by many worse made hands. Checking keeps the pot small out of position and avoids opening ourselves to a raise.

Ace-high with no pair or draw on a paired board; checking back the turn keeps the pot small and avoids betting into a range that can easily have a queen or an eight.

Our sevens and eights have showdown value, but a bet is unlikely to get called by many worse hands on this coordinated river. Checking keeps the pot small and preserves our ability to evaluate an opponent's bet.

Ace-high has little showdown value on a paired, three-club board, and a river bet is unlikely to fold better hands often enough to be profitable. Checking realizes the free showdown.

85 offsuit is too weak for a standard button open against two unknown opponents. Folding avoids investing in a hand with poor equity and limited postflop playability.

K4 offsuit is too weak to continue out of position against the big blind, even heads-up after the button folds. Folding avoids building a pot with a dominated, poorly coordinated hand.

Ace-three offsuit is playable on the button in three-handed play, so I open to 2.5 big blinds to take the initiative rather than flat-calling.

In a 3-handed pot, the button opens wide, and 97s is a reasonable 3-bet bluff from the small blind. It has good playability and avoids flatting out of position with the big blind still to act behind me.

Nine-three offsuit is too weak to continue against an open and a large three-bet, especially with the original raiser still to act. Folding avoids investing further in a very low-equity hand.

A3 offsuit is too weak to continue against a small-blind 3-bet; calling risks domination and a 4-bet bluff is poorly placed.

Pocket jacks on the button in a 3-handed game are a strong value hand, so I'm opening to 2.5bb to build the pot while I'm likely ahead.

KTo is a reasonable light three-bet against a wide button opening range, with a king blocker and some postflop playability. Raising avoids a passive out-of-position call and pressures both the opener and the big blind.

Jack-deuce offsuit is far too weak to continue against an open and a 3-bet to 11 big blinds. Folding preserves the stack for better spots.

JJ plays well as an in-position call against a wide 3-handed small-blind 3-bet. Calling keeps their bluffs in the pot and avoids bloating it against QQ+ or AK.

This board favors my preflop three-betting range. A small continuation bet gets value from Qx and draws while denying equity, without building an overly large pot with a modest kicker.

Small c-bet into a 3-bet pot gives about 4.3:1, so I need roughly 19% equity. JJ has enough against a range-betting SB that includes bluffs and draws, and it can improve to a set or straight, so calling beats folding or turning the hand into a bluff with a raise.

Top pair with a ten-high flush draw has good showdown value, but the third spade makes betting for value less attractive. Checking controls the pot and keeps weaker hands and bluffs in the opponent's range.

JJ with no spade is behind much of the small blind's 3-bet range on a K-Q board where the flush just completed. Checking back keeps the pot small and lets us realize our showdown value without getting raised off our equity.

Top pair has useful showdown value, but a river bet gets limited value from worse while stronger kings and flushes remain possible. Checking keeps the pot controlled and leaves room for missed draws to bluff.

JJ has showdown value against a 3-bettor who has given up, but a bet is rarely called by worse on a K-Q, three-spade, wheel-possible board. Checking back is best.
