Hold'em table

Button open with a suited-ish connector type hand (89) in 3-handed; raising to apply pressure on the blinds.

JTo in the big blind facing a 2.5x button open with 150 to call into a 400 pot gets good odds; it's a standard defend with decent playability, while 3-betting is marginal.

JT offsuit missed the 3-7-6 flop entirely; as the out-of-position BB caller, checking to the preflop raiser is standard and keeps the pot small with only overcards and a backdoor straight draw.

I have an open-ended straight draw (6-7-8-9 with board 3-6-7), so a continuation bet here builds the pot while I have good equity and fold equity against a checking opponent.

JT high with no pair, no draw on a 3-7-6 board facing a c-bet; overcards alone don't justify calling and a check-raise bluff has little equity backup.

2-Ten offsuit is a very weak hand in early position. With no information suggesting a favorable situation, folding preserves chips for better opportunities.

Button folded; T7 suited is a standard raise from the small blind heads-up against the big blind, having good playability and fold equity rather than limping.

JTo is playable heads-up with position postflop; calling the small raise is cheap and keeps the pot manageable.

As the preflop aggressor on a monotone Q-high board, a small one-third pot continuation bet with my whole range applies cheap pressure; T7 has no club and little showdown value, so folding out hands like A-high or small pairs is the main goal and I can give up if raised or called down.

I hold Tc with three clubs on board giving me a flush draw plus an open-ended straight draw (K or 9), a very strong combo draw worth raising for fold equity and value.

Th7h has no club and completely whiffed a monotone Qc2c8c board; facing a check-raise to 700 with just ten-high and no draw, folding is clearly correct.

76o on the button in a 3-handed game is a reasonable open-raise with position; small raise to 2.5bb keeps it cheap and pressures the blinds.

J7 offsuit is weak out of position facing a raise; not worth continuing.

Q6o is a weak hand that doesn't warrant investing further against a raise to 250 chips from the button, especially when facing a min-raise cost of 400+ with no favorable position or hand strength to justify the risk.

Weak offsuit low cards (3s4d) on the button facing a raise-free pot still costing 100 to call with poor equity; folding preserves chips.

T8o (offsuit) is a weak hand in 3-max play, especially out of position as small blind. Folding avoids playing a marginal hand against the big blind's range, preserving chips for better opportunities.

With A-7o on the button in a 3-handed game, raising to 3x the big blind is a standard aggressive play that builds the pot with a strong hand (ace-high) while maintaining position advantage and applying pressure to the blinds.

J3 offsuit in the small blind facing a 3x button open is a clear fold; it plays poorly out of position and is dominated by the button's raising range.

T2 offsuit is a weak hand facing a 3bb raise from the button; folding is correct.

Q7 suited on the button in a 3-handed game is a standard open; raising to 2.5bb with position gives good fold equity and playability.

Weak offsuit low cards facing a raise; not worth defending from SB.

Jack-seven offsuit is a weak hand in isolation. Seat 3 raised to 250 from the button, and calling would require investing 150 more into a 550-chip pot out of position with a marginal holding that is unlikely to be ahead. Folding preserves chips for better opportunities.
