Hold'em table

Q6o is too weak to profitably open from the button even in 3-handed play.

Button folded, so this is heads-up versus the big blind. J8o is playable enough to raise for the dead money and take the initiative rather than flat out of position.

5-8 offsuit is one of the weakest hands and I'm facing a raise from the small blind, needing to call 200 more. With poor equity and no position, folding is clearly best.

73 offsuit is too weak to open first-in from the button, even with position. Folding avoids investing chips with a hand that rarely flops well and is dominated when called.

A8o on the button in a 3-handed game is a standard open-raise for fold equity and positional advantage postflop. Raising to 3x the big blind applies pressure on both blinds without overcommitting.

4s 2s is far too weak to defend out of position against a 3bb button open.

Jack-four offsuit is too weak to continue against a button open, especially out of position for 200 more.

J9s is a standard open on the button in 3-handed play, so we make a standard 2.5bb raise.

43 offsuit is too weak to continue out of position against a button open; folding preserves chips.

Facing a 2.5x button open in a 3-handed game, A7o in the big blind has enough equity against a wide steal range to justify calling 150 into a 400 pot, though I'll be cautious postflop out of position with a dominated ace.

I flopped top pair with a weak kicker and the pot is checked to me; checking controls the pot and keeps seat_1's range wide. I can call a reasonable bet or value-bet later streets depending on action.

I hold top pair with a good kicker on a draw-heavy flop, so I am betting roughly 40% of the pot for value and protection.

I have a gutshot plus overcard draw with decent equity against seat_1's range; calling keeps the pot small while retaining fold equity on later streets. Raising with only ace-high risks isolation against a strong range.

I hold A-high on a coordinated 9-8-3-2 board with the pot already at 1000 chips; checking keeps the pot controlled and avoids bloating it with a weak marginal hand.

Top pair with a jack kicker has solid showdown value; checking behind controls the pot size and allows us to evaluate or bluff-catch on the river.

My A-high is likely no good after two streets of calls, but with the pot already at 1000 and no reads suggesting a bluff, checking keeps the pot small and avoids losing more chips with a marginal hand.

We have top pair with a good kicker and solid showdown value. The river 7 completes some straights and two-pair combinations, so checking behind to realize equity against missed draws and worse pairs is prudent.

J9o is playable enough on the button in three-handed to open for initiative rather than limp or fold. A 2.5bb raise keeps the pot small while applying pressure.

Facing a 2.5x raise from the button with 9d7d out of position against two players; the hand is too weak to call profitably and folding preserves chips for better spots.

AKs is a premium holding in the big blind facing a button open, making a 3-bet to 10bb optimal for value and initiative.

J9o is too weak to continue against a BB 3-bet to 1000; it is dominated too often and does not have the equity or playability to call or 4-bet.

Holding 32o in the small blind, this is the weakest possible starting hand and not worth completing out of position.
