Hold'em table

J9o is playable from the button in three-handed poker, so I open to 2.5bb rather than limp or fold.

K4 offsuit is far too weak to defend from the small blind against a 2.5x button raise, especially out of position with a dominated king. Folding is clearly the best EV play.

K3 offsuit is weak against a raise; folding preserves chips rather than calling for a marginal hand out of position.

K7o is a marginal but playable button open three-handed; a 2.5x raise pressures the blinds and can often take the pot preflop, while limping would give the blinds cheap odds.

Weak offsuit low cards facing a raise; not worth continuing from the small blind.

Q9 offsuit is too weak and poorly playable out of position against a button open, so folding is the higher-EV decision.

I'm on the button with pocket deuces; a standard raise applies pressure and builds a pot to potentially flop a set profitably against the blinds.

KJo is strong enough to continue versus a 3bb button open in three-handed play, but three-betting from the small blind with the big blind still to act leaves me out of position too often. Calling keeps the pot manageable and realizes equity.

Pocket tens are strong against a button raise plus a caller; 3-betting from the big blind builds the pot and isolates, while still keeping room to fold if I run into an overpair or heavy resistance.

KJo is too weak to continue out of position against a BB three-bet after the button folds; calling or raising would often be dominated.

74s is playable as a button open in three-handed poker, so I raise to 2.5bb rather than limp or fold.

Queen-seven suited is marginal, but the 2.5x button raise gives me good pot odds (200 into 400) and suited cards flop well; I'll fold to any 3-bet from the big blind or heavy postflop pressure since I'm out of position with a weak kicker.

2-5 offsuit is a weak hand facing a raise and call; not worth continuing.

I hold queen-high with no draws on an ace-high flop against the preflop raiser, so a donk bluff has poor fold equity and no backup. Checking costs nothing; I can fold to a bet or reassess if I improve.

I have no pair, no draw, and no relevant blockers on A-T-2, so a flop bluff has little equity or fold equity justification. Checking keeps the pot small and preserves a free turn.

The board paired aces, so my Q-high kicker only makes a weak pair of aces; any ace in seat_1's range beats me, so I have no value bet and prefer to check and keep the pot small.

I have no pair and no draw on a double-ace board, so there is no value in betting. Checking keeps the pot small and realizes the free card.

My hand plays itself as aces and tens with a queen kicker from the board; betting only folds out worse and gets raised by AK/TT/AA, so a free showdown is optimal.

Board two pair with only a 7 kicker; checking is free and a river bluff is unlikely to fold better kickers, pairs, aces, or tens.

Nine-four offsuit is far too weak to play even for a single blind from the button in a 3-handed game; folding preserves chips for better spots.

Q5 offsuit is weak heads-up against BB with button folded; folding the small blind is standard here to avoid investing more with a subpar hand.

K2 suited on the button, raising to isolate and take initiative preflop.

Ten-four offsuit is too weak to continue against a button open, especially out of position with the big blind still to act. Folding avoids putting more chips in with a dominated, unconnected hand.

Nine-five offsuit is far too weak to defend against a 3x button raise out of position; folding loses only the blind already committed.
