Hold'em table

8-6 offsuit on the button in a 3-handed game is a marginal hand; folding avoids playing a weak offsuit hand out of position against two unknown opponents.

9-3 offsuit is a very weak hand out of position heads-up against the big blind, not worth completing even for a small price.

7-2 offsuit is a very weak button hand and not worth entering against both blinds.

K5o is a decent hand heads-up in the small blind, and completing costs only 50 more to win a 300 pot. A cheap call with a playable king-high is better than folding, and raising out of position with a weak kicker is marginal.

Button folded and SB limped; J9o is a decent hand heads-up in position-less but with initiative, so I raise to isolate and take the pot or play a bigger pot with a playable hand against a capped limping range.

Getting 3-to-1 on a call of 200 into a 600 pot. K5o has roughly 38-40% equity against a big blind raising range heads-up, so the call is profitable even out of position.

Top pair (king) with a heart flush draw on a Q-K-A board, heads-up, out of position. Pot is 600. Betting about 2/3 pot for value and protection seems right, given the many draws and strong ranges. I'm choosing a mid-size bet.}

Holding Jh9c on QhKhAh gives a strong draw: any heart makes a near-nut flush (only Th beats it) and any ten makes Broadway, ~12 outs. Pot odds of 400 into 1400 are comfortably met, and calling keeps the pot manageable in case villain already has a flush.

Top pair with a heart flush draw is a strong semi-bluff and value hand. Betting about half the pot builds the pot and denies equity to hands like Ax and Qx.

Holding Jh on a three-heart board gives me the nut flush draw (A/K/Q hearts are on board) plus a gutshot to Broadway with any ten; 12 outs at ~27% equity with pot odds of 26.7% plus implied odds makes calling correct.

I only have a pair of kings on a very coordinated board where any ten makes a straight and many hands beat me. Betting would mostly get called by better hands, so I check to get to showdown cheaply.

Pair of jacks on a monotone AKQ board with four-to-a-straight; villain barreled two streets then checked. Betting only gets called by better hands, so check and take the cheap showdown.

AJo is a strong hand in 3-handed play from the button, so a 3x raise is good value and takes the initiative against the two blinds.

T6 offsuit from the small blind facing a 3x button open is a clear fold; it plays poorly out of position and lacks the equity to call or 3-bet profitably.

5-2 offsuit is far too weak to defend against a button 3x open, especially out of position heads-up.

7-4 offsuit is a weak hand from the button in a 3-handed game; folding avoids playing a dominated hand out of position postflop against two blinds.

9-4 offsuit is too weak to complete from the small blind against the big blind.

Open-raise the button with this playable suited-connectivity-like hand profile in a short-handed game, applying pressure to the blinds while retaining postflop maneuverability.

AKo is a premium hand in 3-handed play. A 3-bet from the small blind against a button open builds the pot with a strong hand, and the BB is still to act behind.

2-5 offsuit facing a 3-bet to 900 with an open raiser still to act is a trivial fold; no equity or playability to justify 800 more.

7-high offsuit is too weak to continue against a substantial small-blind 3-bet at this stack depth.

J6 suited is a weak hand out of position against two players, and calling 100 into a 150 pot is marginal. It plays poorly postflop, so I'm folding.

9-4 offsuit is a weak hand out of position against the big blind; completing or raising blind-vs-blind with this holding is marginally -EV, so folding the small blind is fine.
