Hold'em table

K5o is too weak to profitably open from the button even in 3-handed play.

Q4o in the small blind heads-up against the big blind, getting 3-to-1 to complete (50 to win 150). Queen-high has enough equity and playability to call rather than fold, and a raise would bloat the pot with a weak hand.

Ace-high is strong against a small-blind limp. Raising applies pressure and builds a pot when I likely have the better hand.

Q4 offsuit is weak against a big blind 3-bet-sized raise to 400 with a player left to act behind no one; calling 300 more out of position with a dominated hand is unprofitable.

A6 suited-wise is offsuit but decent in 3-handed play on the button; calling 100 to see a flop with good pot odds is reasonable, while raising risks getting dominated.

KJo is strong enough to raise against a button limp, and a 5bb total raise pressures the limper while accounting for my positional disadvantage.

Holding an unsuited 8-5 offsuit against a substantial small blind raise and a button limp is an easy fold.

A6s on the button gets a good price: 400 to call into a 700 pot, and the only opponent left is the small blind who raised. Calling keeps the hand cheap and realizes equity in position, without bloating the pot out of position against a range that dominates A6.

The dry ace-high flop favors my preflop raising range. A small bet can fold out some weaker hands while limiting my risk with king-high.

Top pair with a decent kicker (Ad with 6s gives two pair: aces and sixes) on a dry-ish board is strong. Two pair Aces and Sixes is very strong; raising for value and protection against draws is best.

K-J high has no meaningful draw on this dry ace-high flop. Calling the raise would require too much equity, and a bluff re-raise is unlikely to be profitable.

T6 offsuit is too weak to open profitably from the button against two players at 100bb.

Q9o is sufficiently strong to open with a raise blind-versus-blind after the button folds.

6-9 offsuit is weak, and calling 200 more out of position against a small blind raise to 300 (3x) would be a marginal, losing play. Folding costs only the 100 already posted.

76 offsuit is too weak to open from the button in a 3-handed game.

Ace-deuce suited is a strong hand heads-up against the big blind after the button folded. Raising to 3bb from the small blind builds the pot and takes the initiative.

Q9 offsuit is strong enough to defend the big blind against a small-blind raise, especially with position after the flop.

Ace-high on a paired 8-8-4 board is likely best against a wide big blind range, and I'm first to act. A small bet of half the pot gets value from worse hands like small pairs and draws and denies equity, and I can fold to heavy pressure.

Q9 has no pair, club, or useful backdoor draw on this paired, two-club flop. Facing a half-pot bet, I have better hands to continue with.

Q8o on the button in a 3-handed game is a reasonable, playable hand, and calling 100 to win a 250 pot gets a good price with position, so I'll see a flop rather than fold or inflate the pot.

Completing for 50 chips is inexpensive with a connected hand, while raising out of position with 98 offsuit is less attractive.

I am in the big blind with 2d 6c facing two limpers and have a free option to see the flop.

I have nine-high with little drawing potential in a three-way pot, so I’ll check rather than bluff into two opponents.

Holding a gutshot straight draw with six-high in a multiway limped pot, checking to see a free turn card is the most prudent play.

Top pair (queens) with a mediocre kicker on a dry board, and both opponents checked. I'm on the button, so I bet about two-thirds of the pot for value and protection against overcards and draws.

With nine-high, no pair, and no meaningful draw, calling the flop bet is not profitable.

I only have a gutshot straight draw with six-high out of position, getting insufficient pot odds to justify calling a 200-chip bet.

K5 suited is strong enough to open on the button three-handed. A 2.5-big-blind raise pressures the blinds while keeping the pot manageable.

T6s is too weak to defend out of position against a button raise.

7s3s is a weak hand, and calling 150 to win 400 out of position against a button raise is marginal. Folding avoids playing a weak hand out of position.
