Hold'em table

Opening pocket threes on the button is standard in 3-handed play. A 2.2bb raise puts pressure on the blinds while keeping the pot manageable.

8-4 offsuit is a weak hand facing a raise and will have to act out of position; folding is clearly correct.

A5s is a solid hand in the big blind against a button min-open-ish raise to 220. Getting 370+120 pot odds, calling is clearly profitable, and the hand plays well postflop; a 3-bet is also possible but calling keeps it simple.

Top pair with the nut flush draw's backdoor... actually a top pair with a weak kicker and a nut-ish backdoor; I'm first to act in a heads-up pot, so a small value bet of 300 into 490 builds the pot and charges worse aces and draws.

Holding an underpair of threes on an Ah-Jd-9h flop facing a donk bet from the big blind offers very little equity or playability, making a fold straightforward.

Weak offsuit holding (96o) out of position relative to two opponents yet to act after my raise; not worth continuing given it's not even my blind.

J8 suited is a reasonable hand heads-up in the small blind, and completing costs only 50 to win a 150 pot, so calling is a good price.

I have 32s in the big blind facing an SB limp; checking allows me to see a free flop in position.

Flop is 7h Qs 7d with me holding 8d Jd, giving a gutshot-ish/backdoor flush draw and 8-high pair-with-board only. Heads up out of position, a small 100 bet takes a cheap stab at a pot of 200 on a paired board where the BB's range is weak and often folds.

I hold 3-high with no pair and minimal draw potential on a paired board facing a half-pot flop bet.

J8 offsuit on the button in a 3-handed pot is marginal. Calling 100 into a 250 pot is not terrible, but the hand plays poorly out of position against two blinds, so I fold.

A6o is well ahead of a random blind hand, making an open-raise standard blind vs blind.

4d9d offsuit is weak against a raise from the small blind; folding is correct given the cost to continue and marginal hand value.

9c 6s is too weak to open raise or call from the button, making fold the standard play.

With the button folded it's effectively heads-up vs the big blind; A6o is strong enough to raise for value and fold equity here.

J4o is weak. Calling 200 more to win 400 would need about 33% equity, and I'd be out of position against a small blind raiser who is probably playing a wide range. Fold is the simplest choice.

Ad6d suited is a decent button hand; raising to 3x isolates the limpers and builds pot with position advantage.

QJo out of position in the small blind facing a 3x button open with the big blind still to act is marginal. Calling 250 more with a weak, dominated offsuit hand is not worth it in a 3-handed pot, so I fold.

Holding 53 offsuit facing a 3bb open from the button, this hand has poor playability and equity out of position, making it a clear fold.

4-5 offsuit is a weak hand, so I'm folding it from the button. Calling 100 into a pot of 150 would leave me out of position postflop with a hand that rarely wins at showdown.

94o is far too weak to complete or open-limp from out of position against the big blind.
