Hold'em table

K4o is too weak to open from the button in a standard 3-handed structure.

Aces are the strongest starting hand; I raise for value heads-up against the big blind to build the pot and isolate.

The raise is from the small blind after the button folded, so its range can be wide. 5-4 offsuit is weak but has enough equity at this price to defend rather than fold or inflate the pot.

As the preflop raiser on a K-high dry flop, a half-pot continuation bet folds out underpairs and missed hands, and I retain backdoor spade/straight equity if called.

I have only five-high with no meaningful draw on this flop, so calling the bet would be too costly.

On the button in 3-max, T7o is worth a cheap steal attempt against two blinds; a small raise builds pressure while keeping risk low if re-raised.

T9 offsuit is a marginal out-of-position hand against a sizable button raise, with the big blind still to act. The call price and poor postflop position make folding preferable.

32o is the worst starting hand in Hold'em and cannot profitably defend out of position against a 3bb open.

7-2 offsuit is a very weak hand, and calling from the button offers poor value even with position.

In a blind-versus-blind battle after the button folded, raising pocket threes to 3bb builds value and applies immediate pressure on the big blind.

Q6o is far too weak to defend the big blind against a 3x small-blind raise, especially out of position with poor postflop playability. Folding avoids bleeding chips with a dominated hand.

Open-raising with A2o from the button in 3-handed play is standard to apply pressure and utilize position.

84s is far too weak to defend out of position against a button min-raise; calling 150 into a small pot with dominated suited trash loses equity long-term.

KTo is strong enough to defend the big blind against a small button raise, but calling keeps weaker hands in and avoids bloating the pot out of position.

I have a strong king-high flush draw, but the preflop raiser has the initiative on this ace-high monotone flop. Checking keeps the pot manageable and lets me respond to a bet with my equity.

Check back with top pair weak kicker and a low flush draw to control pot size on a monotone board.

I have a king-high flush, so a small value bet can get calls from weaker flushes while limiting losses against higher hearts. The checked-through flop makes a modest turn bet appropriate.

Getting 4-to-1 pot odds against a small turn probe bet, calling with a made flush (even the lowest) and top pair is profitable against bluffs and random hands.

I have a strong king-high flush and can get value from lower flushes or bluff-catchers after my opponent checked the river. A modest bet also limits losses if they have the rare straight flush.

I hold a flush on a four-flush board. Although the 2 of hearts is the lowest possible flush card, villain's bet size is modest and I only need to beat bluffs without a heart at favorable pot odds.

J9o is playable on the button in a 3-handed game, where I need to open wider and can leverage position postflop. A small raise to 2.5x risks little while applying fold equity to the blinds.

8-6 offsuit is too weak to continue against a button raise, especially from the small blind with the big blind still to act.

74o is a weak, unsuited hand that does not warrant defending out of position against a button open.

As the button in a three-handed pot, 9-8 offsuit is playable and can apply pressure to the blinds. A modest open raise builds initiative without committing too much with a marginal hand.

Holding 9s 2d out of position against a button raise is an easy fold.
