Hold'em table

Pocket jacks are a premium hand in 3-handed play from the button, so I raise to 3bb for value and to build the pot against two blinds.

32 suited is far too weak to call a 3x button raise from the small blind with the big blind still to act.

9-3 offsuit is a very weak hand out of position against a button 3x open; folding is clearly correct despite the pot odds.

84 offsuit on the button is too weak to call a big blind even in position three-handed; folding preserves stack versus negative equity.

Button folded, so I'm SB vs BB heads-up with T8o, which is a reasonable raise in a blind-vs-blind spot; a 3x open takes initiative and often wins the pot outright.

K3 offsuit is a marginal hand, but heads-up against a small blind's 3x raise I get 2:1 pot odds (200 to win 600) and the hand has some equity, so I call rather than fold.}

Middle pair of tens as the preflop raiser on a K-T-7 board; a small 1/3-pot c-bet denies equity to overcards and gutshots while keeping the pot manageable out of position.

Top pair on a K-T-7 board is strong enough to continue against a small continuation bet of 200 into 600. Calling keeps weaker hands in and gets good pot odds, and the weak kicker argues against raising.

Second pair with a weak kicker out of position after the flop bet got called; checking controls the pot and avoids bloating it against Kx while keeping bluff-catching options.

Top pair on a K-T-7-4 board against a heads-up opponent who checked the turn after betting the flop. A bet of 400 into the 1000 pot gets value from weaker pairs and draws and denies equity. My kicker is weak, so I keep the size small.

Second pair on Ks Tc 7h 4c facing a 400 bet into 1000 gives ~22% pot odds; opponent's range after calling preflop and flop includes flush draws, straight draws, and weaker pairs, so a call is justified while raising or folding is too extreme.

I have tens and kings (two pair via board K) with a weak kicker; villain bet the turn after I checked, suggesting a K or strong hand. Checking keeps the pot controlled and lets me evaluate a river bet rather than bloating with a marginal hand.

I hold trips kings with a king kicker (Kc with Ks, Kh on board), a very strong hand. Seat_3 checked the river after calling the turn, so a value bet of about 40% pot should get called by weaker kings, tens, sevens and draws.

Kings and tens with an 8 kicker is a solid bluff-catcher against a sub-half-pot river bet; we beat all busted club and straight draws (QJ, J9, 98) and only lose to Kx or better Tx, and pot odds of ~22% justify a call.

T8o on the button in a 3-handed game is a reasonable open-raise; stealing the blinds with position is profitable and the hand plays fine postflop.

J9 offsuit is weak out of position in the small blind facing a button open to 250 with the big blind still to act behind. Calling 200 more would leave me with a marginal hand and poor postflop position, so folding is best.

7-4 suited has modest equity against a button raise but poor realizability out of position from the big blind, so folding avoids a marginal defense.

K3 offsuit on the button is a marginal hand. Calling out of position postflop against two players with a weak kicker is likely -EV, so I'll fold.

6-4 offsuit is a very weak hand out of position against the big blind; calling or raising risks more chips with poor equity realization than folding the small blind.

8-6 offsuit is a weak gapped hand below a profitable button open or limp range, with poor equity when called by the blinds.

Button folded, so it's SB vs BB heads-up; J8o is a standard open-raise from the small blind against a single opponent with 100bb stacks. Raising to 3x takes initiative and often wins the blinds.

7-2 offsuit is the worst starting hand; calling 200 more to win a 400 pot out of position is not worth it against a small blind raise.

A4 suited on the button in a 3-handed game is a standard open; raise to 2.5bb to take initiative and play in position.

J3 offsuit is a weak hand out of position against a button raise with the big blind still to act. Calling 200 more is not profitable, so I fold.

KTo has strong equity against a wide button open in 3-handed play and gets good pot odds to defend the big blind, while 3-betting out of position would bloat the pot with a marginal hand.

With only king-high on a queen-high two-club board after defending the big blind, I have little equity and no draw; checking keeps the pot small and avoids bluffing into the preflop raiser's range.

Heads-up in position as the preflop raiser on a dry Q-high board; a half-pot c-bet with ace-high and backdoor spade/wheel equity takes down the pot often and keeps initiative.

King-high with only one clean overcard and backdoor straight draws lacks the ~25% equity needed to call out of position against a preflop raiser's flop bet on a Q-high two-club board, and will face further pressure.
