Hold'em table

42o is an unplayable hand preflop even from the button in a 3-handed game. Folding is standard.

With the button folded, Q5 offsuit is strong enough to complete the small blind heads-up, but not strong enough to build a larger pot out of position.

A-T offsuit is a strong hand heads-up against a limped small blind, so I raise for value and to take the initiative in position-less spot with a modest 3x sizing.

Q5 offsuit plays poorly out of position against a big-blind raise, so calling another 200 chips is not worthwhile.

6-2 offsuit is too weak to open from the button without a reason to expect both blinds to fold often.

5h8c is a weak offsuit hand. Out of position against the big blind, I would rather fold than pay 50 more to see a flop with it.

Queens are a premium hand on the button in a 3-handed pot, so I raise to 3bb for value and to build the pot while I have position.

Holding Ah Kd in the small blind against a button open, raising to 1000 chips (10bb) builds the pot for value out of position.

6-2 offsuit is too weak to continue against a large three-bet with the original raiser still in the hand.

QQ on the button facing a small blind 3-bet to 1000 is a strong hand. A 4-bet to 2800 builds the pot with the best hand and gives me a good chance to get stacks in against worse holdings.

AK offsuit is a standard 5-bet all-in 100bb deep 3-handed against a button 4-bet, maximizing fold equity and equity realization.

QQ is strong against a small blind who has shoved all-in over my 3-bet. I need to call 7200 into a 12900 pot, about 36% equity required, and QQ comfortably beats that against a wide shoving range.

74s is too weak to profitably open from the button even in 3-handed play. Folding preserves equity.

With 5-2 offsuit, completing the blind would leave me out of position with a weak hand. Folding avoids investing more chips.

K2 offsuit is a reasonable button open three-handed. Raising to 2.5 big blinds uses position to pressure the blinds.

9-5 offsuit is a weak hand out of position in the small blind, facing a button raise to 250 with the big blind still to act behind me. Folding is the best option.

QhTh is far too strong to fold getting excellent pot odds (150 to win 400) defending the big blind against a button open.

Check out of position to the preflop raiser with a gutshot straight draw.

A small continuation bet uses my preflop range advantage to pressure the big blind's unpaired hands. With king-high and few ways to improve, I don't want to build a large pot.

We hold Queen-ten with no backdoors, only a gutshot straight draw out of position on an Ace-high board, which doesn't offer adequate direct or implied odds to call.

Q3 offsuit is a weak hand. Even on the button in a 3-handed game, it plays poorly against two other players, so I fold and save the 100 chips.

Holding an unplayable 82o out of position against the big blind, folding is the clear optimal play.
