Hold'em table

QTo is a standard opening hand on the button 3-handed; raising to 3x builds the pot with position and applies pressure to the blinds.

A4 offsuit is weak against a sizable button raise, and calling out of position with the big blind still to act risks a difficult multiway pot.

Facing a 3bb open from the button, 98 offsuit lacks sufficient equity and playability out of position to justify calling.

QJo is a solid button open in a three-handed game. Raise to 300 to apply pressure from position and take initiative.

Q5s is too weak to defend out of position against a 3x button open with the big blind still to act.

Fold T8o from the button as it is too weak to open profitably even in 3-handed play.

72o is one of the weakest hands in hold'em; even suited, it has almost no equity and no position advantage worth contesting. Folding is clearly optimal.

A4 offsuit is a reasonable blind-versus-blind raise after the button folds; raising to 300 applies pressure while keeping the sizing modest.

82s is too weak to defend against a 3bb SB open, so folding is clearly optimal.

With pocket kings on the button, raise for value and to take the initiative while keeping weaker hands in the pot. A 300-chip total is a solid three-big-blind sizing.

J7o is far too weak to defend from the small blind against a 3bb button raise out of position.

King-five offsuit is too weak to defend against a 3x button raise; it has poor equity and often flops dominated top pairs. Folding preserves chips for better spots.

93o is too weak to open even from the button in 3-handed play.

Heads-up against only the BB, T7o has decent playability and fold equity; a small raise pressures the BB and can win the pot preflop or build a pot with position.

T6 suited has enough equity and playability to defend the big blind against a small-blind open at this price. I’ll call and see the flop rather than inflate the pot with a marginal hand.

I flopped a flush draw (T-high hearts) heads-up; checking keeps the pot cheap and lets me continue for free while retaining fold equity on later streets.

I have no pair or immediate draw, so taking the free card is preferable to bluffing into a checked pot.

I have a heart flush draw plus a gutshot to the 6, so a half-pot semi-bluff builds the pot and can win it outright; I retain fold equity as the preflop aggressor.

The turn bet offers insufficient pot odds for my eight straight outs, and three hearts on the board make some apparent outs potentially unsafe. My hand has little showdown value otherwise.
