Hold'em table

I'm on the button with a suited-ish connector (8d9s offsuit but good connectivity); raising to 250 to build the pot and take initiative against two players who've only limped/blinded in.

JTo in the big blind facing a 2.5x button open with the SB folded: getting 150 to win 400, a profitable defend with a hand that plays well postflop in position-disadvantaged spots.

JTo whiffed the 3-7-6 flop with only overcards and a backdoor straight draw; out of position against the preflop raiser, checking to see their action is standard.

I have an open-ended straight draw (6-7-8-9 with 3 on board) and BB checked, so a continuation bet applies pressure while retaining strong equity if called.

Jack-high with no draw on a 3-7-6 rainbow board facing a continuation bet; overcards are weak outs and we are out of position, so folding is the lowest-variance play.

2-Ten offsuit is a weak hand that plays poorly out of position. Folding saves chips against two active opponents on the button.

Button folded, so I'm in the small blind heads-up against the big blind with T7 suited, a hand that plays well and is a standard raise in SB vs BB. Raising to 3bb takes initiative and often wins the pot preflop or lets me play in position-less but with a playable suited hand.

76o on the button in a 3-handed game is a reasonable steal open; raising to 2.5bb puts pressure on the blinds and keeps position postflop.

J7 offsuit is weak out of position against a raise; folding is cheap and preserves chips.

Q6o is a weak hand that doesn't warrant a call against a 250 chip raise from the button. Folding preserves chips for better opportunities.

Weak offsuit low cards (34o) on the button facing a raise-call situation isn't worth entering in a 3-handed pot; folding preserves chips.

T8o is a weak hand in the small blind facing a big blind who hasn't acted yet. Folding saves chips against likely better hands when the positional disadvantage is significant.

Button folded (fallback), so it's heads-up SB vs BB with J3o. Jx hands are strong enough to open-raise in a blind-vs-blind spot against a passive-looking opponent; raising 3x to take the pot or play with initiative.

T2 offsuit is a weak hand facing a 3bb raise heads-up out of position; not worth defending here.

Qh7h suited on the button in a 3-handed game is a standard open; raise to 2.5bb to take initiative in position.

3c8c offsuit is weak and facing a raise with two players left to act; not worth continuing.

J7o is a weak hand in 3-handed play. Facing a raise to 250 from the button after the small blind folded, calling requires 150 more chips but gives poor odds and puts me in an awkward position out of position with a marginal hand. Folding preserves chips for better opportunities.
