Hold'em table

65o is too weak and poorly playable to open from the button for a full big blind. Folding avoids a dominated, low-equity spot against two live blinds.

Heads-up against only the big blind, J4s is worth a small steal attempt; a raise to 250 pressures the BB to fold or play a dominated hand out of position.

K9 offsuit facing a raise from SB with only one player left to act is a weak spot to continue; folding preserves chips.

Ace-two offsuit is too weak to play from the button against two blinds with no reads; folding avoids dominated spots and preserves the stack.

Heads-up vs BB with a suited king, a small raise to isolate and take initiative is reasonable given wide range advantage.

75o is too weak to continue against a small-blind raise, even heads-up in position. Folding avoids putting more chips in with a dominated offsuit hand.

Button raise with suited connector-ish 7-8 offsuit to steal blinds; sizing is standard 2.5bb open.

68 offsuit is too weak to continue against a button open, especially out of position. Folding avoids paying 200 more with a dominated, low-equity hand.

2c5h offsuit is nearly worthless and I'm out of position against a button raise; calling 150 to chase a weak low pair is -EV. Folding preserves chips for better spots.

K8o is a standard button open in three-handed play; a 2.5bb raise takes the initiative and folds out worse hands.

Pocket sixes play well as a 3-bet from the small blind against a button open; building the pot with a decent pair and applying pressure is better than flatting and playing out of position.

J5 offsuit is weak facing a raise and a large 3-bet; folding is clearly correct.

K8o is too weak to continue against a small-blind three-bet; calling or four-betting would be -EV.

J7 offsuit is a weak hand even from the button in 3-handed play; folding preserves chips for better spots. A min-raise would just build a pot out of position against two players.

Button folded, heads-up vs BB with a suited connector-ish hand; cheap to complete and see a flop rather than raise or fold.

87 offsuit is too weak to raise a limp for value, and checking is free in the big blind heads-up.

Weak backdoor flush draw with no pair and no strong equity; checking behind is fine since action is checked to me.

I have only a gutshot with 87 and no pair or flush draw on K64. With no bet facing me, checking takes the free card rather than bloating a small pot.

Semi-bluff with a four-card club flush draw on a checked-down board; betting here can take the pot now or build value if called.

I have only a gutshot with 87 on a KQ46 board and no pair or flush draw. Calling 120 into 320 needs far more equity than four outs can provide, so folding is correct.

Button raise with a suited king to isolate and take advantage of position against two passive blinds.

Nine-deuce offsuit is too weak to continue out of position against a button open, so folding is the clear choice.

K9 offsuit is marginal against a 2.5x button raise, but calling 150 into a 400 pot gives good odds and the hand plays well if I flop a king or nine; folding is too tight given the price.

I have a king-high flush draw plus a gutshot to the J straight on T-8-Q; a half-pot semi-bluff builds the pot when I hit, folds out ace-high hands that beat me at showdown, and I still retain fold equity with plenty of stack behind.

K-high with only a backdoor gutshot draw isn't strong enough to continue against a flop lead after being called preflop; folding preserves chips.
