Hold'em table

K3o is at the bottom of the button opening range and has poor playability postflop.

Heads-up against the big blind, calling 50 into a 150 pot gives me 3:1 odds, and J2s has enough equity with a suited jack to see a cheap flop.

Button folded and the small blind only completed, so I raise AQo for value and to take control heads-up. A raise to 400 is a standard size with this hand.

J2s is nearly the worst hand in poker; calling 300 more against a BB raise with jack-two suited has terrible equity and no realistic way to win a big pot. Folding is clearly correct.

Six-three offsuit is a trash hand from the button facing a limped pot; calling 100 with no equity edge is -EV, so folding is clearly best.

AJo is well ahead of the big blind's range heads-up after the button folds, so I raise to 3bb for value and fold equity rather than just complete.

Defending A4o in position against a 3bb open from the small blind with favorable pot odds.

As the preflop raiser I c-bet one-third pot on a dry flop with two overcards; BB's calling range is wide and often folds to pressure.

I hold Ace-high with a weak kicker and no significant draw on a Ten-high board, making an easy fold facing a continuation bet.

J8o is too weak and offsuit to open from the button into two live blinds, with poor playability and reverse implied odds if called.

A6s is a premium hand blind versus blind; raising to 300 to build the pot and apply pressure on the big blind.

TJ suited has strong equity and playability against the small blind's wide 3x opening range, and calling 200 into a 400 pot gives me 3:1 odds, making this a clear profitable flat.

I am out of position on a low, connected board that connects well with the big blind's defending range, so checking my Ace-high with backdoor equity is standard.

I only have jack-high with a backdoor flush draw, and the preflop raiser checked the flop, so I take a free turn card instead of bluffing into their range. I can fold or re-attack depending on the turn.

Turned the nut flush draw alongside a straight draw to the five. Betting two-thirds pot to seize initiative and build the pot with tremendous equity.

I only have J-high with a gutshot (~8.5% equity) and need ~29% to call 400 into 1000; even with implied odds the 9 brings too many counterfeits. Bluff-raising a preflop raiser with J-high is too thin, so folding is clearly best.

Opening with AJo on the button is standard; a raise to 2.5bb builds value and applies positional pressure.

J5 offsuit is far too weak to defend the small blind against a 2.5x button raise with the big blind still to act; calling 200 out of position with no pair potential or flush prospects is -EV, so folding loses the least.

83 offsuit is too weak to continue against a button open after the small blind folds, so folding is the highest-EV option.

2-5 offsuit is one of the worst starting hands, and calling 100 into a 150 pot requires far more equity than it has even three-handed. Folding preserves chips for a spot with real equity.

Button folded, so this is heads-up versus the big blind with A8o. Raising to 300 takes the initiative and builds the pot with a playable ace rather than just completing.

Defending A4o in position against a small blind open getting 2:1 pot odds.

Ace-high with no pair or draw on a king-high flop has little bluff equity against the preflop caller, so I check and keep the pot small.

I have second pair with top kicker in position; checking behind controls the pot and realizes equity against the small blind's checking range.

Ace-high with no pair or draw on a king-high board; checking controls the pot out of position and realizes whatever showdown value I have.

I have middle pair of fours with an ace kicker and a gutshot straight draw. Checking back controls the pot and realizes my equity in position.

I have the wheel with As on a 2-3-4-5 board, losing only to a six. After two streets of checks, a two-thirds-pot bet gets value from kings and pairs without overplaying the second nuts.

I rivered a wheel straight with Ah 4c. While a 6 makes a higher straight, the SB's range contains many Ax hands we chop with and some missed bluffs, making a call clearly profitable.

K2o is too weak to open or limp from the button; it is dominated often and has poor equity when called, so folding is the highest-EV line.

Nine-four offsuit is well below the threshold to complete or raise from the small blind against the big blind.
