Hold'em table

K8o from the button is playable in 3-handed; a raise puts pressure on the blinds and can take down the pot preflop.

Q5o from the small blind facing a button open with the big blind still to act is too weak to call out of position, and it isn't a good 3-bet bluff candidate. Folding is standard.

Q9o in the big blind facing a button open to 250 is a marginal hand. Calling 150 to get 400 in the pot is about 27% pot odds, but I would be out of position with a dominated hand. Folding is simple and cheap.

92s on the button 3-handed sits at the bottom of a reasonable opening range, and both blinds are left to act behind me. Folding is the cleanest play.

T3 offsuit is a weak hand. Heads-up against the big blind, completing costs 50 more to win a pot of 150 and I'd be out of position postflop, so folding is slightly conservative but reasonable.

T8 offsuit on the button in a 3-handed pot is playable, and calling 100 to win a 250 pot gives a good price. Raising with a marginal hand risks getting out-kicked or 3-bet, so I'll see a flop.

5h 4s is too weak to continue out of position, even with the low cost to call; folding saves chips for better opportunities.

82o is weak; checking gives a free flop against the button's limp.

Complete air out of position on an ace-high board against a button limper; checking keeps the pot small, and I can give up cheaply if they bet.

Heads-up on the button after the BB checked the flop. I have a backdoor straight draw and a backdoor flush draw with Td, and the BB's check range is weak. A small bet of about half the pot is a reasonable stab to take the pot or build equity.}

8-high with no draw on an A-Q-4 two-diamond board. Folding to the small bet is fine, since a raise as a bluff has little fold equity against a button limper who connected with an ace-high board.

J7o is a weak hand, but in 3-handed with the button acting first preflop, a min-raise can often steal the blinds. Folding is too tight, and calling invites pressure.

KQo is well ahead of a 3-handed button min-raise range, so I 3-bet from the SB to take the initiative and avoid playing out of position in a multiway pot.

A3o in the big blind facing a button open and a small blind 3-bet to 900 is weak. Calling 800 more out of position with the button still to act, and possibly a squeeze behind, is not profitable, so I fold.

J7o is too weak to call a 9bb 3-bet, even in position. I fold and preserve my stack for a better spot.

A8o is a clear open from the button in 3-handed play; a standard 2.5bb raise puts pressure on both blinds.

7-9 offsuit is a weak hand out of position in the small blind facing a button open and a big blind still to act. Calling 200 more is not worth it, so I fold.

Closing the action from the big blind with 8h5h, I'm getting about 2.67:1 and have a playable suited one-gapper against a wide button open.

I have 8h5h with no pair and no draw on a monotone club board. Checking is the safe play to see what the preflop raiser does.

A-high with the nut flush draw and an overcard on a board that favors the preflop raiser; a small c-bet gets folds and builds the pot for the draw. I'm keeping the size at about a third of the pot.

My hand is very weak (8-high, backdoor straight draw) on a monotone board with three clubs. The pot odds do not justify chasing a gutshot, and I may already be drawing dead against a made flush.

Q9 offsuit is a marginal hand, and out of position against two players after the button acts, it plays poorly. Folding is a small-cost, low-variance choice, though a call or small raise from the button would also be defensible in 3-handed play.

My hand 43 offsuit is extremely weak, I'm out of position against the big blind, and calling would just bleed chips.
