Hold'em table

A5s is a strong suited ace on the button, so I open to 3x to take the initiative and fold out weaker hands.

Holding 92s out of position facing a 3bb open from the button is a clear fold.

73s gets good pot odds (needs ~24% equity) against a wide 3-handed button open, so it's a profitable defend from the big blind.

Out of position with 7-high and only a weak gutshot (needs a 9 for J-T-9-8-7? no—needs 9 and J), this board hits the button's raising range well, so I check and plan to fold to a bet.

Ace-high with no pair and no draw on T-Q-8 has little fold equity worth paying for after a preflop caller checks. Checking back keeps the pot small and avoids turning a weak hand into a bluff.

I have 7-3 with no pair and no real draw on a broadway-heavy board. The button's checked-back range still has plenty of K/Q/T hits, so bluffing has little fold equity and I'll check and give up.

Ace-high with no pair or draw on a king-queen-ten-eight board has little showdown value, and seat 3 has checked. Checking keeps the pot small rather than bluffing into a range that can easily have a pair.

Seven-high has almost no showdown value, and the button checked back the flop and turn, so his range is capped. The third heart on the river lets me credibly represent a flush and fold out weak pairs and ace-high.

Ace-high with no pair or flush on a paired-looking river loses to any made hand, and a 450 bet after two streets of checks is not priced well enough to hero-call.

Opening A3o from the button is standard in 3-handed play to exert positional pressure.

T5 offsuit from the small blind facing a button open, with the big blind still to act behind, is a clear fold. Calling out of position with a weak, dominated hand loses money.

ATo is strong enough to defend the big blind against a button min-raise, and calling 100 into 350 is the right price out of position.

Ace-high with no pair or draw on K64; checking is free and keeps the pot small out of position against the preflop raiser.

Dry King-high board heavily favors the preflop raiser's range, so a one-third pot continuation bet exerts good pressure.

Ace-high with no pair and no draw is too weak to continue against a flop bet, even a small one. Folding preserves chips for better spots.

A4o on the button in a 3-handed game is a standard open-raise; a 2.5bb raise uses the blocker and position.

T6o is too weak to continue out of position against a button open; folding avoids paying 200 with a dominated, unconnected hand.

KTo is well ahead of a wide 3-handed button opening range, and getting attractive pot odds (150 to win 400) closing the action makes calling standard.

I missed this paired flop from out of position and will check to the preflop raiser with my King-high.

A small c-bet on this dry paired board works well, since the big blind's calling range misses often and our ace-high has some equity plus fold equity.

Facing a flop c-bet out of position on 7-9-7 with just King-high and no strong backdoors, KTo lacks sufficient equity and playability to continue.

K6 offsuit is too weak to open from the button against two live blinds, so folding preserves chips.

Opening from the small blind with a pocket pair after the button folds. Raising to 3x to take initiative blind versus blind.

In the BB against an SB raise to 3bb, A3o is getting 3:1 and plays well in position, so calling beats folding. A 3-bet is also possible, but a call keeps their weaker hands in.

We hold a full house on a trips board. Betting a third of the pot protects against overcards that could hit a higher full house on the turn while getting value from floating hands.

On the 444 board, ace-high is a strong bluff-catcher against a small c-bet from the SB, who will be betting many unpaired hands. The bet is 200 into 600, so calling keeps their bluffs in the pot and leaves room to re-evaluate on the turn.

We have a low full house (fours full of threes). Checking controls the pot since any Ace or higher pocket pair beats us, while worse hands won't call a bet.

We hold aces full (444AA), losing only to the last 4 and chopping with other aces. A mid-sized value bet when checked to should get calls from pocket pairs and ace-x.

We hold a full house (threes full of fours), which comfortably beats all of villain's float/bluff stabs on the turn. Getting nearly 3.7:1 pot odds, calling is profitable against their bluffing range.

I hold a full house (fours full of threes). Checking allows the opponent to bluff or value bet worse hands such as trip fours with an Ace kicker.

With fours full of aces I only lose to AA or a 4, and I chop with other aces. A medium bet gets value from kings and pocket pairs that will call.

Our fours full of threes loses to any pocket pair, any Ace, and any King. Given seat_3 called the flop on trip fours and bet both the turn Ace and river King, their range is heavily weighted toward hands that beat us, making this an easy fold.

65 offsuit is too weak to open from the button even in 3-handed play, making a fold the standard +EV decision.

A4o is a solid blind-vs-blind hand and well ahead of a random big blind range, so raising to 3bb applies pressure and takes the initiative.

T2o is too weak to continue against a preflop raise; folding saves chips for better spots.

93o is too weak to open from the button in 3-handed play at 100bb; a fold is standard.

K3 offsuit is too weak and poorly playable to complete or raise from the small blind heads-up, so folding is the lower-variance choice.
