Hold'em table

Q3 offsuit is too weak to continue out of position against the big blind after the button folds, so I give up the small blind.

K2 offsuit is too weak to open from the button in a three-handed pot, so folding preserves chips.

QTo in the small blind vs big blind only after button folds is a standard open-raise; raising to 3bb takes initiative and wins the blinds often.

9s5h is a weak hand facing a 3bb raise out of position; folding is clearly best.

On the button with 5d3d suited connector-ish in a 3-handed game, a small open raise is standard to steal blinds and play in position; folding is too tight and limping gives up initiative.

5-6 offsuit is too weak to continue out of position against a button open after the small blind folded.

T2s is too weak to complete out of position heads-up against the big blind, so I fold rather than invest more.

Q8o is playable as a button open in three-handed play, so I raise to 2.5bb rather than limp or fold.

J7 offsuit in the small blind facing a button raise is a clear fold; it plays poorly out of position and doesn't have the equity to call or 3-bet profitably.

2c6c is a weak hand facing a 2.5x raise heads-up; folding is clearly best.

A7o on the button in 3-handed play is a standard open; raising to 2.5bb takes initiative against the blinds.

Pocket jacks play well against a 2.5x open; calling keeps the pot manageable and preserves 3-bet options postflop.

A6 offsuit is too weak to continue multiway against a raise and a call; folding avoids a dominated, low-equity spot.

I have an overpair of jacks heads-up on K84; a standard continuation bet builds the pot and applies pressure.

Donk bet into the preflop raiser on a dry K-high board is often weak or a draw; raising in position with ace-high plus backdoor club/straight equity applies pressure and folds out many 8x/draws.

JJ is an overpair on K-8-4; calling 550 keeps the pot manageable while retaining equity against AK, sets, or draws.

The Qh is a bad card for my jacks; seat_3 showed flop aggression, so I'll check and keep the pot small, folding to significant turn pressure.

Ace-high has almost no showdown value against a flop donk-call range; a second barrel represents the KQ/AK/overpair hands in my preflop-raising range and should fold out 8x, 4x, and some weak Kx while the turn Q is a strong scare card.

My jacks are an overpair and I've already invested 1150; pot odds of about 2.85:1 justify one call, though seat_3's triple-barrel aggression suggests a strong K or set.

Jacks are only a bluff-catcher here; seat_3 has fired three streets and the board beats my pair often. Checking keeps the option to fold cheaply to a river bet.

Ace-high has showdown value against missed club/diamond/straight draws that gave up on the river, while a third barrel would mostly fold out hands we already beat and get called by Kx/Qx/sets that check-called two streets. Checking back realizes equity cheaply.
