Hold'em table

Q8o is a marginal but playable button open in three-handed poker, so I raise to 2.5bb for position and fold equity rather than limp.

Ace-Jack offsuit is strong three-handed against a button open, so I 3-bet for value and to isolate, also discouraging a cheap call from the big blind behind me.

Folding T6o against an open and a 3-bet is standard due to weak hand strength and being out of position.

Q8o is too weak to continue against a small-blind 3-bet; folding avoids a dominated spot with poor equity.

Three-handed, the button opens very wide and Q7o is inside that range; a standard 3x open to 300 pressures the blinds and lets me play in position postflop when called.

Q6o is far too weak to defend from the small blind against a button open.

ATo is strong enough to continue against a single button open, and calling 200 into 450 is better than folding or bloating the pot out of position.

Ace-high with no pair or draw on K82 rainbow is too weak to bet out of position into the preflop raiser. Checking keeps the pot small and preserves the option to continue if the turn improves me.

As the preflop raiser facing a flop check, I take the initiative with a small c-bet; Q-high can fold out overcards/pairs and I preserve fold equity cheaply.

Ace-high with no pair and no draw on K-8-2 does not have enough equity to call a 350 flop bet, and raising as a bluff is too thin out of position.

Q6o is too weak to profitably open on the button in 3-handed play.

Button folded, so this is heads-up versus the big blind. Suited connectors play better with initiative, and a small raise takes the lead cheaply while still folding out some better hands.

62 offsuit is one of the worst hands in hold'em, and I'd be out of position facing a 3x raise from the small blind. Calling 200 more with ~25-30% equity against a raising range is clearly -EV; the blind is sunk cost.

T2s is a standard button open in three-handed play; a small raise uses position and fold equity against the blinds while keeping the price low with a marginal suited hand.

Nine-eight offsuit is far too weak to call a 2.5x button raise out of position, with the big blind still left to act behind me. Folding preserves chips for better spots.

Getting attractive pot odds of 2.67-to-1 closing the action heads-up with a pocket pair, calling is standard.

Check to the preflop aggressor with fourth pair on a high board.

Ten-deuce has no pair, draw, or useful blockers on Ks-Js-8h, so a flop bluff is poorly placed. Checking is free and keeps the pot small with a hand that rarely improves.

I hold pocket deuces on a board of J-8-K-4, giving me minimal showdown value. Checking allows me to realize any river equity for free without bloating the pot out of position.

I have complete air with no pair or draw on a dry board, so checking to realize a free river is the lowest-variance line.

We rivered a disguised set of deuces after checking flop and turn. Betting around 60% pot targets calls from stubborn second pairs, weak kings, or pocket pairs.

Bottom pair with a weak kicker is too thin to call a river bet after the opponent checked flop and turn. The price is not good enough against a range that is mostly value.

Ten-four offsuit is a weak hand even from the button against two players who have already invested blinds; folding preserves chips with minimal loss.

In a blind versus blind situation, Q7s is a strong hand that plays well as an open-raise to apply pressure on the big blind.

T2o is too weak to continue against a 3bb open; folding avoids a dominated, hard-to-play hand out of position.

J5s is near the bottom of playable button ranges in 3-handed play; folding cleanly avoids playing weak marginal holdings out of flow postflop.

T2o is too weak to play out of position for a small-blind complete; folding avoids a low-equity, hard-to-realize spot against the big blind.
