Hold'em table

T9s on the button in a 3-handed game is a clear open-raise; raising to 2.5bb takes initiative with a hand that plays well postflop in position.

J3 suited is too weak to defend from the small blind against a button open with the big blind still behind.

Q6s is too weak to continue out of position against a button open; it is often dominated and has poor reverse implied odds.

7-4 suited is too weak to profitably open from the button at these stack depths.

Button folded, so this is heads-up versus the big blind. Q2s has some suited equity and a small raise can take the pot down or let me play the flop with initiative.

Button folded, SB raised to 3bb; I'm in the BB with 76o getting 2:1 with position postflop. 76o is a marginal but reasonable defend heads-up vs an SB open, so I call.

Queen-high with no pair or draw has little flop equity, so I take the free check rather than bluff into the caller.

Open-ended straight draw (6-7 on 9-8-4) in position after the preflop raiser checks; semi-bluff bet to take the pot now or build it while holding 8 clean outs.

Queen-high with no pair or draw is too weak to continue against a flop bet.

Three-handed on the button, 78o is a reasonable steal open rather than a limp. A small raise pressures the blinds while keeping the price manageable if called.

Q6 offsuit from the small blind facing a button raise is a clear fold; it plays poorly out of position against a raiser and the big blind still to act.

3c5s offsuit is too weak to defend versus a button raise, especially out of position heads-up.

T3 offsuit on the button in a 3-handed game is a weak, unsuited, disconnected hand; folding avoids a marginal spot even though button opening ranges are wide.

8-6 offsuit is a weak heads-up blind hand with poor realization; folding avoids playing a disadvantaged pot.

7-5 offsuit is a weak button holding and not worth entering against two blinds at this stack depth.

Button folded, so I am heads-up with the big blind holding pocket eights. A raise to 300 builds the pot and gets value from worse hands rather than just completing.

9-5 offsuit is a weak hand facing a 3x raise from the small blind; calling 200 into 600 out of position with poor playability is unprofitable, so fold.

53 offsuit is too weak to open from the button for a full big blind; folding preserves the stack.

Button folded, so it's SB vs BB heads-up; J4o is a marginal hand but with position disadvantage I prefer a small raise to take the pot down often against a wide BB range rather than limp-calling out of position. A 3x open is standard for blind-vs-blind steals.

7c3c is a very weak offsuit-equivalent defending hand versus a small-blind raise, with poor realization out of position.
