Hold'em table

KTs is a decent button hand in a 3-handed game; raise to build the pot and take initiative since blinds are limited-range.

45 offsuit out of position against a 2.5x button raise is far too weak to defend from the small blind; calling 200 more with a hand this dominated when flops rarely connect is clearly -EV.

AJs is strong enough to 3-bet the button's 2.5bb open from the big blind; 800 builds the pot and denies easy equity.

King-Jack suited-ish position play: raising from the button with KJo is standard to steal blinds and build a pot with a strong broadway hand.

A7s has enough equity and playability versus a button open to continue, but calling keeps the pot smaller out of position rather than bloating it with a marginal three-bet.

8-3 offsuit is a weak hand facing a raise and a call; folding is correct here.

Top pair with a weak kicker on a connected flop; checking controls the pot out of position and avoids building a large pot against a button raiser's stronger Ax and two-pair hands.

Middle pair of jacks with a gutshot to Broadway and a diamond backdoor gives me a solid continue-bet on the button after the SB check; betting around 57% pot charges draws and Ax while keeping the option to fold to a raise.

I have top pair on a wet AJT board and the price is fine against a button c-bet. Raising with a weak kicker mostly gets called by better, so I call and reassess the turn.

I have aces and jacks on a paired board, strong enough to bet for value but not the nuts, so a modest half-pot bet gets called by worse pairs and floats while limiting damage against trips or the straight.

87o is playable enough from the button in three-handed poker to open rather than limp or fold, and a small raise takes the initiative with fold equity.

J7 suited from SB facing a raise and cold call with BB still to act is a weak spot, easy fold.

Pocket sixes have decent set potential and only 150 more to call into a 400 pot, so calling is clearly profitable; a 3-bet out of position with a medium pair risks bloating the pot without much fold equity.

My 66 makes two pair (nines and sixes) on this paired flop, which beats all of the preflop raiser's unpaired overcards and overpairs. Betting ~3/4 pot builds the pot and charges draws while I'm ahead.

Bottom pair with no flush draw on a paired board is too weak to continue against a flop bet.

Button steal attempt with a marginal but playable Q-high hand against two blinds in a 3-handed game.

3c6c is a very weak hand facing a 2.5x raise from the button; calling 200 into a small pot with poor equity and no position is unprofitable.

K8 offsuit is too weak to defend out of position against a button open; folding avoids a dominated, difficult postflop spot.

Ace-eight offsuit is a decent button hand 3-handed; a small raise builds the pot with position and can win blinds immediately.

K2o is too weak to continue from the small blind against a button open, especially with the big blind still to act.

A8s is a clear open from the button in three-handed play; a 3bb raise builds the pot and applies pressure on the blinds.

4-6 offsuit is weak; facing a 3bb raise with two players left to act isn't worth continuing.

Pocket tens are well ahead of a button's 3x opening range, so I 3-bet to build the pot and apply pressure while retaining fold equity.

A8s is too often dominated by a BB 3-bet and does not have enough equity or implied odds to continue for 600 more.
