Hold'em table

Pocket fours is a solid button open in three-handed play, so I raise to 300 to build the pot and take the initiative rather than flat-calling.

J4 offsuit is too weak to defend the big blind out of position against a 3x button raise; expected realization is below the price.

King-high hand on the button with two players already in; a standard raise builds the pot while I have position for the rest of the hand.

4-6 offsuit is very weak out of position in the small blind facing a button raise; calling 200 lacks the equity and playability to be profitable.

K9 offsuit is too weak to continue out of position against a button open; calling 150 does not offer enough equity or playability.

T6 offsuit is a weak hand even on the button in 3-handed play; calling or raising risks chips with poor equity and playability.

96 offsuit is too weak to complete from the small blind against the big blind after the button folds. Folding saves the remaining 50 chips.

J3o is too weak and poorly connected to open from the button into two live blinds. Folding avoids spewing chips with a hand that rarely flops well.

KQs is a premium hand heads-up against the big blind after the button folded; raising builds the pot and isolates.

J6 offsuit is weak and poorly connected against a small-blind 3x raise; defending out of the big blind would require too much equity and playability postflop.

K7o is a weak opening hand from the button in a 3-handed pot; not worth committing chips preflop.

KJo is strong heads-up in the small blind versus the big blind after the button fold; raising builds the pot and denies equity.

42 offsuit is too weak to continue against a preflop raise, even heads-up from the big blind. Folding saves chips for better spots.

T3 suited is below a profitable button open or limp range in 3-handed play, with poor kicker and limited straight potential despite position.

Q7 offsuit is too weak to complete or raise from the small blind out of position against the big blind, so folding saves chips.
