Hold'em table

A6o is playable on the button in a 3-handed game, and raising applies pressure to the blinds while taking initiative.

Holding Q3o in the big blind against a 3x button open is a clear fold due to reverse implied odds and poor equity out of position.

K7o on the button is marginal; limping along by calling the small blind completion keeps the pot small and in position versus two players who've already acted.

Holding 92o out of position, even for half a blind, has deeply negative expected value postflop.

KJo is strong enough to punish a button limp and take initiative, while a small raise controls risk if called.

K7o facing a raise from the BB with only one opponent left is not worth continuing out of position-ish for value; fold and preserve chips.

A7s is a strong opening hand on the button in 3-handed play; raising to 2.5bb to build the pot in position.

A8o has enough equity against a button open and the price is good, so I call rather than fold or bloat the pot out of position.

A4 suited is a speculative hand worth a cheap call from the big blind given the small raise size and multiway pot.

A-high with a backdoor nut flush draw is not strong enough to bet into two preflop callers out of position; checking controls the pot and keeps options open.

Ace-high with a backdoor flush draw, no made hand yet; checking keeps pot small and lets me see a free card.

Multiway pot on a coordinated broadway board hits callers' ranges well; checking back to realize our Ace-high equity and control pot size.

Semi-bluffing with ace-high and a gutshot to Broadway; the flop checked through, so a turn bet can fold out better unpaired hands and apply pressure.

I only have bottom pair with a weak kicker and no draw; facing a turn bet, the pot odds don't justify continuing against a likely stronger range.

I only hold ace-high with a gutshot straight draw, giving me roughly 4 outs. The pot odds of 400 to win 1150 do not justify calling, especially since any river Queen puts four to a straight on board and kills implied odds.

On the button in a 3-handed pot, T7o is a reasonable open to apply pressure and take the blinds; I can fold to a reraise.

87o offsuit from SB facing a raise and a cold call ahead is a clear fold; not worth defending with weak connectors here.

54 offsuit is too weak to defend out of position against a 3x button open.

4-7 offsuit is a weak hand not worth playing from the button facing a raise, especially with two players behind to act after the blinds.

J6o is too weak to profitably complete or raise from the small blind out of position.

54s is a standard open-raise on the button in 3-handed play due to its playability and position.

K7o is too weak to continue out of position against a button raise, especially with the big blind still to act. Folding avoids playing a dominated hand with poor implied odds.

2-6 offsuit is a trash hand facing a raise; folding is correct with weak equity and no pot odds to speak of.
