Hold'em table

Pocket Jacks on the button is a premium hand; raising to 3x builds the pot in position and charges weaker hands.

3d2d is a weak hand out of position in the small blind facing a 3x button open with the big blind still to act. Calling 250 into a 450 pot is not worth it, so I fold.

9-3 offsuit is a very weak hand out of position against a button open; folding is standard despite decent pot odds.

8-4 offsuit is a weak hand out of position against two players, so folding to the 100 bet is the disciplined choice.

Button folded, so it's SB vs BB heads-up; T8o is a standard open-raise from the small blind against one opponent with 100bb stacks.

K3o has enough equity against a wide small-blind open and I am in position postflop, getting a good price to defend my big blind.

As the preflop raiser on a K-T-7 flop with middle pair, a small c-bet of a third of the pot denies equity to overcards and gutshots while keeping the pot manageable out of position.

Top pair on a dry K-T-7 board facing a small one-third pot bet heads-up; calling keeps pot controlled with a weak kicker while being ahead of bluffs and Tx.

Middle pair with weak kicker on a K-high board after being called on the flop; checking controls the pot and avoids bloating it with a marginal hand out of position.

Top pair on a drawy board after opponent checked turn; bet half pot for protection and value from Tx, 7x and draws, folding to a raise with weak kicker.

Middle pair of tens on K-T-7-4 is a bluff-catcher with decent equity vs villain's stab range (draws like QJ, J9, clubs, weaker Tx); getting 4:1 pot odds justifies one call, then reassess on the river.

Kings and tens with a weak kicker on a paired board; villain bet the turn after my check and could easily have Kx. Betting is too thin out of position, so check and decide against a bet with bluff-catching intent (missed club draws).

I have trip Kings with only one King left in the deck, so opponent rarely has a better King or full house. A half-pot value bet can be called by two-pair hands like Tx or pocket aces that checked the river.

Two pair kings and tens with 8 kicker on a paired river; opponent bets half pot so I need ~25% equity. Their range includes missed draws (QJ, J9, 98) and weaker Tx along with Kx, so calling is profitable while raising would only get called by better.

T8o on the button in a 3-handed game is a reasonable open-raise; first to act with position on both blinds, a 2.5x raise applies pressure and plays well postflop.

J9 offsuit is too weak to call out of position from the small blind against a button raise with the big blind still behind, and it is not a good 3-bet bluff candidate.

Getting 400 to 150 (about 2.7-to-1) in the big blind against a button raise to 2.5bb, so 7h4h has enough equity and suitedness to defend. Folding gives up too much, and a 3-bet bluff is not needed.

I have 7h4h on a Th Ad 8s board, which is a weak hand with only a backdoor heart draw. I'm out of position against the preflop raiser, so I check and give up the initiative rather than bluff.

I flopped two pair (tens and eights) on an A-high board; betting for value against the big blind's calling range, which includes many aces and draws. A ~2/3 pot bet builds the pot while charging straight draws.

7h4h has only a backdoor flush draw on an Ace-high, Ten-high board and faces a 350 bet into 900 from the button, who is likely to have an Ace or a Ten. Calling would cost 350 with weak equity and poor implied odds, so folding is best.

On the button in 3-handed play, K3o is ahead of blind ranges and benefits from fold equity and position. Raising to 3x applies pressure rather than limping.

6-4 offsuit is a weak hand out of position in the small blind, facing a 3x button raise with the big blind still to act. Calling 250 more isn't worth it, so I fold.

2c3s offsuit is one of the worst starting hands; facing a 3x button open out of position, folding is clearly correct despite the pot odds.

8-6 offsuit is a weak hand out of position postflop against two opponents, so folding on the button is the disciplined play rather than paying 100 to see a flop with it.

Button folded, so it's SB vs BB heads-up; J8o is a standard open-raise from the small blind in this spot, taking initiative against one opponent.

7-2 offsuit is the weakest starting hand and has poor equity against a small-blind raise to 300, so calling 200 more is unprofitable.

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

J3 offsuit is too weak to call a button raise from the small blind, especially out of position with the big blind still to act.

KTo in the big blind getting 400 into 150 (about 2.7-to-1) against a button min-raise is a clear call; the hand is too marginal to 3-bet and has good playability in position-disadvantaged heads-up.

Top pair with a king on a dry Q-8-2 flop is likely best against a button open-raiser's wide range. A bet of about 64% of the pot gets value from worse queens and draws and denies equity, and I'm first to act heads-up.. Actually the king is not top pair: the queen is the top card, so I hold king-high with a gutshot-less overcard and a backdoor draw, so this is a small stab on a dry board.}

A4s missed the Q82 two-club flop entirely with no club; facing a 350 donk bet into a 550 pot with just ace-high and a backdoor draw, folding is the disciplined play.
