Hold'em table

A2 offsuit is a reasonable button open three-handed, with an ace blocker and positional advantage. Raising to 2.25 big blinds pressures the blinds without risking too much with a marginal hand.

K6o is too weak to defend out of position against a button open with the big blind still to act.

J5o is too weak to continue out of position against a button open; folding avoids a dominated, hard-to-play hand.

A6s is a clear open raise from the button in 3-handed play.

T9o is playable enough versus a 2.5bb button open to continue, but it is not strong enough to 3-bet for value out of position. Calling keeps the price reasonable and sees a flop.

Calling costs 150 to contest a 750-chip pot, and 8♠5♠ has enough suited and straight potential to defend at this price. Closing the preflop action also eliminates the risk of a squeeze behind me.

T9 offsuit has no pair and no draw on Q74 with two hearts, so checking multiway is the highest-EV line.

With only a gutshot and no backdoor flush draw, checking is preferable to bluffing into two opponents. It preserves the chance to see a free turn without building a pot out of position.

In a three-way pot on a wet Q-high board, checking behind with Ace-high and backdoors controls the pot and realizes equity in position.

Open-ended straight draw with no pair and two players behind; checking keeps the pot small and realizes the draw for free.

Second pair with a weak kicker has showdown value, plus a gutshot straight draw. Checking controls the pot in a three-way hand and avoids building it against stronger pairs.

I have Ace-high with a gutshot straight draw in position. Checking behind takes a free card to realize equity without risking a check-raise.

I have ten-high with no pair, straight, or flush on the river, so there is no value in betting into two opponents. Checking realizes the free showdown.

My pair of eights has showdown value, but a river bet is unlikely to get called by worse often enough against two opponents. Checking preserves that value without inflating the pot against queens, kings, or stronger eights.

In a three-way pot, bluffing the river after checking flop and turn has low fold equity against two opponents who may call with any weak pair. Checking behind allows me to realize whatever showdown value Ace-high has against missed draws without risking additional chips.

32o is too weak to open from the button for a full big blind; folding preserves chips.

Completing the small blind costs only 50 chips into a 150-chip pot. J5 offsuit is sufficient to limp heads-up, keeping the pot small with a marginal hand out of position.

Holding K9s in position against a small blind limp, raising to 350 isolates for value and takes initiative into the flop.

J5 offsuit is too weak to defend against this raise out of position. Its poor playability and domination risk make folding preferable to calling 250 more.

23 offsuit is too weak to open profitably against two blinds without evidence that they overfold. Folding avoids investing chips with poor equity and playability.

K4o has poor playability out of position against the big blind, making an easy fold preflop.

K9o is a standard opening hand from the button in 3-handed play, so we open for 2.25x.

A2s is playable in a three-handed pot against a small button open, and calling 175 into 375 is priced well enough to see a flop rather than fold a suited ace.

T3 offsuit has poor equity realization against a button raise and small-blind call. Even with favorable pot odds, folding avoids an unprofitable multiway defense.

Paired flop gives me only fives with an ace kicker and no real draw, so I check to the preflop raiser rather than inflate the pot.

Check behind with King-high on a paired low board to realize equity and control the pot size in position.

Trips are on the board and I only have the ace kicker, so I check to control the pot rather than bet into possible full houses.

I have King-high kicker to the trip fives on board. Checking behind controls the pot and realizes showdown value against missed broadway draws.

Board trips with an ace kicker is ahead of unpaired kickers, and a small river bet can get thin value from stubborn kings or weaker aces after the preflop raiser checked two streets.

The board contains trips, so any pocket pair has a full house, any seven has a straight, and any Ace beats my King-high kicker. Calling only catches undercard bluffs, making a fold the prudent play.

Suited connector on the button is worth a small open; raising to 2.5bb takes the initiative and can fold out worse hands before the flop.

QTo is a marginal offsuit hand facing a button raise from the small blind, with the big blind still to act. Folding avoids playing a frequently dominated hand out of position.

Holding 8s 2d offsuit in the big blind facing a button open is an easy standard fold.
