Hold'em table

Q6 offsuit is a marginal but playable button open three-handed, with position on both blinds postflop.

J8 offsuit is weak out of position from the small blind, facing a button open with the big blind still to act behind me. Calling 170 more would put me in a poor spot, so I fold.

Holding 85o in the big blind facing a button open is well below the defending range, so folding is standard.

7-3 offsuit is the worst starting hand and I'm out of position postflop against two players, so folding to the 100 call is best.

Fold 86o in the small blind as it is too weak to complete or raise profitably out of position.

Opening A8o on the button in a 3-handed game is standard for value and position.

4♠2♠ is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

J4 offsuit is weak; calling 150 to win 400 gives about 27% pot odds, but the hand plays poorly out of position against a button raiser, so folding is best.

J9 suited is a strong button opening hand three-handed, and a 2.5 big blind raise can win the blinds or build a pot in position.

4-3 offsuit is one of the weakest hands. Calling 200 more out of position against a button raise, with the big blind still to act behind me, is not profitable.

Getting attractive pot odds of 150 to win 400 against a button open, A7o has plenty of equity to defend in the big blind.

Check to the preflop aggressor out of position with an overcard and a gutshot straight draw.

Top pair with a jack kicker is strong heads-up on this flop. A bet gets value from weaker pairs and charges draws.

We only have Ace-high with a weak kicker and no direct straight or flush draw against a substantial continuation bet out of position.

J9 offsuit on the button in a 3-handed pot is marginal. Calling 100 to win 150 is close, but the hand plays poorly out of position against two opponents postflop, so I'm folding to avoid a marginal spot.

97s is a strong suited one-gapper well within the standard SB raising range against the big blind.

AK suited is a strong hand to three-bet against a small-blind open. Raising to 1100 builds the pot while compensating for being out of position.

Fold 97s out of position facing a sizeable 3-bet from the big blind.

J2s is too weak to profitably open-raise from the button even in 3-handed play.

With 3-2 offsuit out of position against the big blind, the cheap call is still difficult to turn into a profit.
