Hold'em table

Nine-four suited is far too weak to open from the button against two random hands; folding preserves chips for better spots.

Heads-up pot after button folds; Q9o is a reasonable hand to raise for value and to take initiative against the big blind.

Calling costs 150 into a final pot of 500, requiring 30% equity. Against a typically wide small-blind opening range, 7-5 offsuit has enough equity and benefits from postflop position in a rake-free pot.

I raised preflop and the board (5-5-7) is unlikely to have hit either opponent hard, so a continuation bet with my overcard hand can take down the pot.

My flopped full house is strong enough to build the pot immediately. This raise can extract value from overpairs, trips, and some 7x hands while setting up larger bets on later streets.

I have no pair and no draw on a paired board facing a large raise; easy fold with just Q-high.

Button with a wide 3-handed range; J8o can profitably raise to pressure both blinds and take the pot with fold equity.

A9 offsuit is a reasonable three-bet against a wide button opening range, and the ace blocks strong continuing hands. Raising rather than calling pressures the big blind and avoids playing a multiway pot out of position.

Facing a large 3-bet to 1000 with weak offsuit J8, folding is clearly correct given poor equity and reverse implied odds.

QJo is a strong enough hand to open on the button three-handed. Raising to 2.5 big blinds pressures the blinds while preserving positional advantage if called.

7♠6♣ offsuit is too weak to defend a 2.5x raise out of position with only 150 more to call but poor postflop prospects 3-handed.

K5 offsuit facing a raise with a call needed is a weak holding; folding avoids committing chips with poor equity and no position.

9o3o from the button is too weak to play even with a limp; folding is the standard profitable line.

Heads-up pot with suited 4-8, cheap to see a flop by calling the extra 50.

Ten-deuce offsuit is too weak for a routine isolation raise. Checking takes the free flop and preserves chips while retaining positional advantage against the small blind.

I have bottom pair with weak kicker and a backdoor flush draw; checking keeps the pot small and avoids building a pot with a marginal hand out of position against two players.

Ten-high has no meaningful draw on this board and is a poor bluff candidate. Checking keeps the pot small and takes a free chance to improve.

I hold trip fours (4s in hand plus board pair of 4s) which is a strong hand; betting builds the pot while both opponents checked the flop, suggesting weakness.

Ten-high has no meaningful draw and very little showdown value against this turn bet. Calling requires 30% equity, and bluff-raising without useful blockers is unattractive.

JTo from the button is a reasonable steal/raise hand against two blinds with no action yet; raising to 300 builds the pot and applies pressure.

A6 offsuit is too weak to defend profitably from the small blind against a 3bb raise with the big blind still to act. Its domination risk and poor out-of-position playability favor folding.

6d7s is a weak suited connector facing a 3x raise out of position; folding is clearly better than calling 200 more with a marginal hand.

K9 offsuit is a profitable button open three-handed. Raising to 2.5 big blinds pressures the blinds while preserving positional advantage if called.

5d9s is a weak hand facing a 2.5x raise out of position; folding is clearly best.

AK is a premium hand; 3-betting the button's open isolates and builds the pot while retaining initiative.

K9 offsuit is too weak to continue against this three-bet, even in position. Its domination risk and poor playability make folding preferable to calling or bluffing with a four-bet.
