Hold'em table

8-6 offsuit is a weak button holding in this setup; folding avoids entering a marginal pot.

9-3 offsuit is among the weakest hands. Out of position against the big blind, I'd need to call 50 more to see a flop, and it plays poorly, so I'll fold.

2-7 offsuit is the worst starting hand; folding on the button costs nothing and avoids a losing spot against two opponents.

Button folded, so it's SB vs BB heads-up; K5o is a standard raise from the small blind against a single opponent, taking initiative and often winning the blinds outright.

J9 offsuit is a reasonable heads-up big-blind defense against a small blind 3x open, with adequate pot odds and playable equity.

Middle pair of kings with a backup heart on a monotone AKQ board; a small bet denies equity to straight/flush draws and gets value from weaker pairs while keeping the pot manageable out of position.

I hold the nut flush on this monotone board. Raising builds value against strong one-heart holdings, sets, and straights while charging draws.

Top pair plus a heart draw on a very wet board; check-raise is strong but we get ~26% pot odds and have outs/showdown value against draws and bluffs, so call without bloating the pot.

Second pair with a weak 5-high flush draw on a monotone board after being check-raised; betting into a likely strong range is bad, so check and decide versus their turn bet.

I have the nut flush with the Jh completing a royal flush, so I value-bet against any heart or strong made hand. A substantial sizing builds the pot while keeping weaker flushes and one-pair holdings in range.

Second pair with only a 5-high heart draw on a monotone AKQ board; villain check-raised the flop and barrels 70% pot on the turn, a range heavy with flushes and straights. I need ~29% equity and my weak flush draw is often dead or dominated, so folding is correct.

AJo on the button in a 3-handed game is a clear open-raise; standard 2.5x sizing to build the pot in position.

T6 offsuit is a weak, dominated hand from the small blind facing a button raise, with the big blind still to act.

5-2 offsuit is the worst hand, and calling 150 more out of position against a button raise to 250 isn't profitable, so I fold.

7-4 offsuit is too weak to open from the button in this short-handed structure.

9-4 offsuit is one of the weakest hands. Out of position against the big blind it isn't worth completing the extra 50 chips, so I fold.

On the button in 3-handed play, 76o is a marginal hand, but calling 100 into a 150 pot gives good odds and position, so I'll take a cheap flop.

AKo in the small blind facing a button limp is a clear value raise; isolating the limper and building a pot with a premium hand.

2s5d is a very weak offsuit hand facing a raise and a caller, with poor equity and reverse-implied-odds potential.

7-6 offsuit on the button, getting 600 into 300 (2:1) against a small blind raise with position. Calling is marginally fine and cheaper than a bluff 3-bet; folding is close but I'll call and play postflop in position.

Preflop raiser with AK on J93 rainbow against a limp-caller; a small c-bet of 1/3 pot takes down the pot often and keeps our range strong, with overcard outs and backdoor straight draws when called.

I have 7-6 on a 9-J-3 board with an open-ended straight draw (needs an 8 or 10 for 8 outs, with some overcard help). The price is 300 to win 1200+, about 4:1 pot odds with decent implied odds, so calling is profitable.

Second barrel as a semi-bluff with a gutshot to the nuts plus overcards; the Q is a strong scare card for my preflop raising range and folds out many of villain's flop-calling pairs like 9x, 88-TT, and weak draws.

I have 7-6 on a 9-J-3-Q board, which is just a gutterless draw at best with no pair. Seat 3 has bet every street, so I fold rather than call 900 into a 2400 pot without enough equity.

J6 suited on the button in a 3-handed game is a standard open; raising to 2.5bb puts pressure on the blinds and takes position.

9-4 offsuit is too weak to defend from the small blind against a button raise with the big blind still behind.

A7o offsuit in the big blind getting 400-to-150 odds (about 2.7:1) against a button raise from a wide range is a clear call. The ace blocks strong hands, and the hand is too marginal to 3-bet for value.

Top pair with a decent kicker on a dry A-3-5 board, heads-up and out of position. Betting about half the pot for value and to charge draws and weaker aces.

Jack high with no pair, no flush draw, and only backdoor straight outs facing a donk bet on an ace-high board; no reason to continue or bluff with zero equity.
