Hold'em table

67 offsuit is too weak to open from the button into two live players; folding avoids a marginal spot with poor equity and reverse implied odds.

In a blind-versus-blind situation, A7o is well ahead of an average holding, so an open-raise to 3bb applies pressure and captures initiative.

Getting 2:1 pot odds (200 to call into 400) with A8o against a likely wide SB steal-raise; calling realizes decent equity cheaply while keeping the pot manageable out of position.

As the preflop aggressor, a small one-third pot c-bet on a paired King board puts pressure on the big blind's wide defending range.

The board pair plays for me and my ace is top kicker, so folding is too tight against a small 1/3-pot bet; raising would only fold out bluffs while getting stacked by Kx or 66, so I just call and re-evaluate on the turn.

I have Ace-high with showdown value and Seat 3 called both preflop and flop. Checking controls the pot out of position.

My pair of kings with an ace kicker only beats unpaired no-king hands here: any Kx makes trip kings and pocket pairs make two pair, so a bluff folds out nothing that beats me. Checking behind realizes my thin showdown equity at zero cost and keeps the pot small when I'm likely beat.

We hold Ace-high without a heart on a three-flush paired board. Checking gives us a free showdown against missed straight draws while avoiding putting more chips into a range that called the flop.

My pair of kings with an ace kicker chops with any other ace and already beats all no-pair hands at showdown since seat_2 checked, while betting only loses chips to pocket pairs, king trips, or the completed heart flush with almost no value upside.

J4o is too weak to open even from the button in 3-handed play.

On the button 3-handed, 86o is well within a wide opening range; a min-raise builds fold equity and keeps the pot cheap if called, and I retain position postflop.

95o is too weak to continue against a button open from the small blind, so folding is the highest-EV line.

J5o is too weak to defend out of position even getting 3.5 to 1 pot odds against a min-raise.

KQs is a strong suited broadway on the button, so I open to 3x rather than limp and take the initiative in a three-handed pot.

K2o is far too weak to defend out of position against a 3bb button open.

Q5 offsuit has very poor equity against a 3x button open range, and calling 200 into a 450 pot requires too much. There's little chance to outplay postflop, so folding is clearly the most profitable play.

Opening on the button with pocket threes to take the initiative and utilize position.

T6 offsuit is far too weak to defend against a button raise with the big blind still left to act, and I'd be out of position postflop. Folding loses the minimum.

QTo has enough equity and playability versus a 2.2bb button open to continue; calling 120 into 370 is the right price out of position.

Top pair on a dry-ish flop is ahead of a wide button open, so a small value bet gets called by worse pairs and draws while keeping the pot controlled.

Holding bottom underpair on a Q-9-2 two-tone board facing a donk bet offers little equity and poor playability, making a fold the clear choice.

7-2 offsuit from the button against two blinds is a clear fold; limp-reraise traps cost more than the small edge this hand can ever produce.

73o is too weak to continue from the small blind even heads-up; folding avoids putting more chips in with a dominated hand.
