Hold'em table

73o is far too weak to open preflop, even from the button in a 3-handed game.

KQ suited is a strong hand heads-up against only the big blind; raising builds the pot with value hands and applies fold equity rather than just completing from the small blind.

JTo is strong enough to defend the big blind heads-up against a small-blind open; calling 200 into 600 needs only about a third equity, which this hand should have.

I raised preflop and the J-5-5 flop is unlikely to have connected with the BB's flatting range; a half-pot continuation bet wins the pot often enough and I keep equity with two live overcards if called.

I have jacks and fives on a paired board, well ahead of a half-pot continuation bet. Raising to 900 builds the pot and charges worse jacks and overcards while still leaving room to continue.

Suited jack on the button three-handed is well ahead of a fold; a standard 2.5x open pressures both blinds and lets me play in position with flush potential while keeping risk low.

A5o is too weak to call a button open out of position with the big blind still to act, and it is a poor three-bet bluff. Folding avoids dominated kickers and difficult postflop spots.

54 offsuit is too weak to defend out of position against a 2.5bb button raise.

Pocket eights are ahead of a random button open range, so I raise to 3x to build the pot and take the initiative before the blinds act.

T6o is too weak to defend out of position against a button raise.

32o is dominated trash; folding against a 3x raise is clearly correct even with 200 to call.

Open-raising 43s on the button in 3-handed play to leverage position and postflop playability.

A2 offsuit is dominated by most button raising ranges and plays poorly out of position with the big blind still to act. Calling 150 into a small pot with a weak kicker is a losing line, so folding is cleanest.

Q7o is too weak and poorly connected to defend the big blind against a button open; folding is the higher-EV play.

76o is weak but button position in a 3-handed game justifies a wide open; raising to 2.5x pressures the blinds and can take the pot preflop with fold equity.

34o is too weak to continue against a button open; folding avoids paying 200 more with a hand that has poor equity and little postflop playability.

Holding 95 offsuit in the big blind against a button open is an easy fold out of position.

T2o is too weak to open even from the button in three-handed play; folding avoids a dominated, low-playability hand.

Q4o is too weak to complete or raise profitably out of position from the small blind against the big blind.
