Hold'em table

4h8d is a weak offsuit hand with poor playability, and calling 100 into a 150 pot out of position relative to the blinds is not profitable. Folding avoids unnecessary risk early with deep stacks.

Pocket fives is comfortably ahead of a random hand in a blind-vs-blind battle; opening to 3 bb puts pressure on the big blind.

K6 offsuit is strong enough to defend the big blind against a small-blind 3x raise, especially with position after the flop.

Holding an underpair out of position on a wet board with two overcards, checking to pot control and evaluate opponent's reaction is the standard play.

King-high has some showdown value and limited immediate drawing equity. Checking in position keeps the pot small and lets me reassess on the turn.

The turn brings a very wet board with straight and flush possibilities, so checking our weak underpair out of position is standard.

The opponent checked twice, suggesting a range that may fold to a turn bet. I can also improve with a club or a seven if called.

Holding an underpair on a wet, four-card connected and flush-draw turn board against a bet offers virtually no equity.

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

Ace-high is strong enough to raise heads-up against the big blind, despite being out of position.

9-3 suited is too weak to defend out of position against a preflop raise, even with 2:1 pot odds. Folding avoids playing a dominated hand.

64 offsuit is too weak to open profitably from the button without a reason to expect the blinds to fold often.

Button folded; A5o has enough equity to raise from the small blind, take initiative, and pressure the big blind.

J8s plays well in position against a small blind open, getting 2:1 pot odds to call.

C-bet small on a paired low board to fold out overcards and take down the pot; if called, I can give up on later streets.

I flopped trips with Jh 8h on an 8c 8d 3d board. Flat calling in position lets the aggressor continue barreling bluffs and weaker hands on later streets.

Ace-high with no pair on a paired board; checking to control the pot and see a free river, avoiding getting raised off the hand.

I have three of a kind on a board with several draws. Betting 60% of the pot extracts value from flush draws, straight draws, and weaker pairs.

Ace-high with no pair or draw on a paired board; facing a turn raise, I have little equity and poor odds, so I fold.

AJo is a strong 3-handed button hand, so I raise for value and initiative. A 3x open to 300 is standard and puts pressure on the blinds.

Folding 54o out of position facing a 3bb open from the button.

QTo has enough equity to defend the big blind against a button open for 200 more, but it is not strong enough to reraise out of position.

Top two pair is strong on this relatively dry flop. Checking lets the preflop raiser continuation-bet, giving me a chance to raise for value.

Continuation-betting as the preflop raiser with two overcards and a gutshot to the nuts, applying pressure on the big blind's flop check.

Top two pair is strong against a button continuation bet. Raising for value also charges straight draws.

AJo on QT5 faces a large check-raise with only a gutshot and overcards. The pot odds are insufficient against a strong range, so folding preserves chips.

T6o is too weak to open even from the button in 3-handed play. Folding is standard.

Pocket nines are strong heads-up against the big blind. Raising to 350 builds value and avoids giving a free flop.

A8o has enough equity against a likely wide small-blind open, and closing the action for 250 into 450 gives good pot odds; 3-betting out of position with a weak ace would inflate the pot unnecessarily.

A small bet with 99 denies equity to overcards while keeping the pot manageable on a paired flop.

I have ace high with position and the small flop bet gives me good odds to continue; calling keeps bluffs in and lets me reevaluate on the turn.

The queen makes my nines a weaker value bet, and the flop call leaves plenty of queens and jacks in my opponent’s range. Checking keeps the pot manageable.

Opponent's turn check suggests weakness; a half-pot bet can fold out draws and under-pairs while representing a strong hand.

The small turn bet can include draws and weaker pairs, so pocket nines have enough bluff-catching value to call. I’ll reassess on the river.

Pocket nines have showdown value, but worse hands are unlikely to call a river bet on this paired board. Checking avoids building a pot against a queen or jack.

My two pair (jacks and eights) has some showdown value, but any Qx or Jx that called the turn beats me. Checking behind avoids value-owning against those stronger hands.

Q9 suited is strong enough to open on the button, and a 2.5-big-blind raise applies pressure while keeping the pot manageable.

T7o is too weak to defend out of position against a button raise, especially with the big blind still to act and poor postflop playability. Folding preserves chips for better spots.

KTo is well within the standard big blind defending range against a button 2.5x open, getting attractive pot odds of 2.7 to 1.

Top pair with a decent kicker out of position against the preflop aggressor; checking to induce a continuation bet.

A small continuation bet pressures the big blind's wide range, and Q9 suited has backdoor straight and flush potential if called.

Flopped top pair with a decent kicker facing a small one-third pot continuation bet; calling keeps their wide range in and controls pot size out of position.

I have top pair with a mediocre kicker and a gutshot straight draw out of position; checking allows me to control the pot size and re-evaluate.

I have a gutshot straight draw but little showdown value. Checking takes the free river card rather than risking more chips against a flop caller.

I have top pair with a ten kicker on a board where many draws missed. Checking allows me to control the pot and induce bluffs or call a reasonable bet from worse hands.

Queen-high has little showdown value. The river completes several straights, so a substantial bet can pressure weaker pairs that called the flop.

I hold top pair with a decent kicker in a pot where the turn checked through. Given the pot odds of over 3:1 and missed flop floats in the opponent's range, calling is a standard bluff catch.
