Hold'em table

As the button in a three-handed pot, 8♠4♠ is a reasonable light open; raising applies pressure to the blinds while retaining postflop initiative.

Q9o is too weak to call or 3-bet from the small blind against a button open, especially playing out of position.

K4 offsuit is too weak to continue against a button open; calling 150 into 400 does not justify the dominated king and poor playability.

Open-raising T7s on the button to apply pressure and play in position.

67o is too weak to continue out of position against a button raise to 2.5bb. Folding avoids paying 200 more with a dominated, unsuited hand.

64 offsuit is weak and difficult to realize equity out of position against the button’s raise. I’ll save the call amount for a better spot.

24o is too weak to open even on the button in three-handed play; folding costs nothing and avoids a dominated, low-equity hand.

T5 suited is playable heads-up from the small blind, and completing costs only 50 chips into a 150-chip pot.

I have a weak holding with 9s 3c in the big blind, so taking the free flop by checking is the standard play.

I have a strong combo draw with an open-ended straight draw and a flush draw, so betting can build the pot and generate fold equity. A modest lead also keeps the risk manageable in this limped pot.

Facing a 62.5% pot bet on a wet board with weak bottom pair and no redraws, folding is the standard play.

Q9 offsuit is a reasonable button open in a three-handed game. Raising to 250 applies pressure to the blinds while keeping the pot manageable.

J6o is well below the threshold to defend from the small blind against a button open.

7-3 offsuit is too weak to continue against a button open; folding avoids putting more chips in with a hand that has poor equity and little postflop playability.

Holding 85 offsuit on the button is too weak to open even 3-handed, making fold the standard play.

84 offsuit is too weak to continue out of position for another 50, even with the button already folded. Folding avoids a dominated flop and preserves the rest of the stack.

K2o is too weak and disconnected to open from the button for value or as a profitable steal, so folding preserves chips.

With the button folded, A-5 is strong enough to raise from the small blind and take initiative heads-up. A raise to 300 applies pressure while keeping the sizing moderate.

Q4o is too weak to defend against a 3bb open from the small blind, even with position postflop.
