Hold'em table

Queen-jack suited is a strong button open, so I raise to 3bb to build the pot and take the initiative before the blinds.

J7 offsuit is weak; facing a 3bb raise with a mediocre kicker hand and a player still to act, folding preserves chips.

Calling 200 into a 450 pot needs only ~31% equity, and T7o has roughly 40%+ against a wide 3-max button open, so defending is +EV despite being out of position.

Ten-high with only a backdoor club draw on an Ac-Qc-5s flop against the preflop raiser; checking is free and keeps the pot small, and a strength-flavored message may buy a free turn card.

I have second pair with a jack kicker on a checked flop, so a small bet gets value from worse hands and denies a free card without bloating the pot against an ace.

I hold Tc with two clubs on the board, giving me a ten-out flush draw; calling 220 into an 870 pot needs only ~20% equity while my draw hits about 38% of the time by the river, so calling is clearly profitable.

I have queens with a jack kicker on an ace-high board, so checking controls the pot against a range that can easily have an ace or better.

I have queens and fives with showdown value, but any ace or five in the caller's range beats me, so a river bet gets called mostly by better hands. Checking behind is the higher-EV line.

AJ offsuit is a strong hand on the button; raising builds the pot and applies pressure to both blinds.

King-three offsuit is dominated by any reasonable raising range and calling 250 more into a 450 pot needs ~36% equity, which this hand lacks. Folding is clearly the best EV play.

Q7 offsuit is too weak to continue out of position against a button open, so folding avoids a dominated spot.

K4o is weak, but on the button in a 3-handed game a cheap min-raise leverages position and fold equity against the blinds; folding here is too tight.

Pocket sevens is ahead of a button min-raise often enough to continue, and calling keeps the big blind in while seeing a flop cheaply.

Q9o is weak facing a raise and a call from multiple players; not worth defending out of position with a marginal hand.

Pocket sevens are behind the king on this flop, so I check out of position and let the preflop raiser act before committing more chips.

I flopped top pair with K4 on K-5-3; betting ~60% pot gets thin value from weaker kings and underpairs while charging flush draws, and I can fold/evaluate if raised.

Pocket sevens is an underpair to the king, but the price is only 300 into 800 and the button's line is consistent with a steal-and-stab. Calling keeps the pot small and sees a turn without inflating against a made king.

Pocket sevens are an underpair to the king and ten against the preflop raiser who continuation-bet, so I check to control the pot and reassess if they bet.

Pocket sevens are only a weak underpair on a king-ten board with three hearts, so betting is unlikely to get called by worse. Checking keeps the pot small and realizes showdown value for free.

68o is too weak to open or limp from the button; folding avoids dominated spots and unnecessary variance.

Pocket queens is a strong hand heads-up against the big blind; raising builds the pot and isolates against a single opponent.

Q3o is far too weak to defend against a 3.5x small-blind raise; I'm dominated by any queen and have poor equity even with position, so folding preserves chips for better spots.

J4 offsuit is a weak hand out of position facing action from both blinds; folding preserves chips for better spots.

Heads-up against the big blind with position post-flop, 86o has enough equity to attack the 150-chip pot; a min-raise to 200 wins it often preflop or builds a small pot where I act last.

Button folded, so this is heads-up in position against a min-raise. Q2s has enough suited equity and pot odds to continue rather than fold or inflate the pot.

I only have a pair of sixes on a Jack-high board with a diamond draw possible; checking keeps the pot small in position and avoids inflating against the preflop caller.

Queen-high with no pair or draw has little fold equity as a bluff, and the flop was checked to me, so I take the free card.

I only hold middle pair (sixes) with a weak kicker on a coordinated board, so checking keeps the pot small and avoids bloating it while likely dominated when called.

Bottom pair with a queen kicker is too weak to bet for value on this turn, and seat_3 has shown no aggression. Checking keeps the pot small and realizes showdown value.

I have only a weak pair of deuces and can see showdown for free after both players checked down. Betting has little value and risks a call or raise from better hands.

Suited connector on the button three-handed is a standard open-raise; I take initiative with position and keep a playable range postflop.

23s is too weak to continue out of position against a button open with the big blind still to act, so folding is the highest-EV line.

Weak offsuit hand facing a 3x raise; not worth calling out of position.
