Hold'em table

Suited jack has adequate equity to open on the button three-handed, and position lets us profitably apply pressure.

72 offsuit is too weak to continue against a button open; folding saves chips.

7-3 offsuit is far too weak to call 150 more against a 2.5x raise; folding is clearly best.

J7 offsuit is too weak to open from the button in a three-handed game, and limping is unattractive, so folding is the highest-EV option.

T9s is a decent speculative hand heads-up; just complete from the SB cheaply rather than bloat the pot with a raise.

T5 suited is playable in a limped blind-versus-blind pot, and checking realizes its equity without inflating the pot out of position.

9-high with a gutshot-ish nothing on A-T-3; checking keeps the pot small and avoids building it with no equity edge.

Betting our middle pair for value and protection on this ace-high board after the small blind checks.

9-high with no draw on a two-spade board facing a flop bet; folding is cheapest and avoids building a pot out of position.

75o on the button is too weak to call or raise into two blinds; folding is the profitable play.

With the button folded, pocket eights are a strong heads-up hand from the small blind. Raising builds value and pressures the big blind's wide defending range.

Q3s is too weak and easily dominated to continue against a 3bb small-blind raise, even with position.

Open-raising the button with Q8 suited applies pressure and leverages positional advantage in a three-handed game.

53 offsuit is too weak to call a raise from the small blind; folding preserves chips.

4d7d is a weak hand out of position against a 2.5x raise; calling 150 more with little equity is unprofitable, so folding is best.

65o is too weak to open from the button for value or as a bluff; folding avoids a dominated, low-playability hand out of position postflop.

Calling the extra 50 from the small blind with K-seven suited is a favorable price heads-up against the big blind.

T4 offsuit has little value heads-up, and the small blind has only completed, so checking is free and keeps the pot small.

Checking preserves our king-high showdown value in a limped pot while retaining a gutshot to a straight. This paired board favors the big blind's range enough that a stab has limited value.

Ten-high has no pair or draw on a paired flop, and the pot is small after a check, so there is no value in betting.

I have a made straight on a paired, connected board. A modest turn bet can gain value from pairs and draws while controlling exposure to higher straights or full houses.

Ten-high with no pair and no draw on a paired board; calling 150 into a small pot is a clear fold.
