Hold'em table

Ten-nine offsuit is playable from the button 3-handed; a small raise builds a pot with position and can win the blinds immediately.

3-7 offsuit is too weak to continue against a button open, especially out of position. Folding avoids putting more chips in with a hand that rarely flops well.

Suited connector getting decent odds to see a flop against a single raiser; not strong enough to 3bet.

No pair or draw on this board, checking to see a free card and control pot size.

No made hand or draw on this paired board; checking behind is best with no equity to push.

I hold trip tens (Td with Tc/Th on board) and seat_3 has shown weakness by checking flop and turn, so I bet around 60% of pot for value against their likely pairs or draws.

I have no pair, no draw, and no showdown value on this paired board; folding to the turn raise is clearly correct.

K3 offsuit is too weak to open even on the button in three-handed play; it is easily dominated and plays poorly when called. Folding preserves the full stack for better spots.

Button folded, I have a decent Ace with A9, so I raise to isolate the big blind and build the pot with a hand that plays well heads-up.

Eight-three offsuit is far too weak to call a 3x raise out of position, even with the extra 200 to call. Folding is clearly the best play.

Weak offsuit low cards (3d8s) with no position advantage worth pursuing; folding preserves chips for better spots.

KJo heads-up after a fold is strong; I'll raise for value and fold equity rather than just call.

76 offsuit is too weak to continue against a small-blind raise to 3bb, even in position. Folding avoids playing a dominated offsuit hand out of the blinds.

J8s is a weak hand, and on the button I'll have position in better spots; folding the trash avoids dominated situations.

Button folded, so this is heads-up versus the big blind with AJo, a clear open. Raising to 3bb builds the pot and denies the BB a free flop.

2d7d is a weak offsuit hand facing a 3bb raise from a seat that has shown aggression; folding is best.

A6o is playable as a button open in three-handed poker, so I raise to 3x to take the initiative and fold out worse hands.

7s4s is a weak suited hand facing a 3bb raise from the button with a player still to act behind; not worth calling out of position.

J6o is far too weak to defend the big blind against a 3x button raise out of position; it is dominated by better jacks and has poor postflop playability, so folding is clearly best.

Button raise with suited ace to take initiative preflop against blinds.

K7s is dominated by stronger kings in the button's raising range and I'm out of position for the rest of the hand; folding loses only the 50 chip blind already committed.

73o is too weak to continue against a button open after the small blind folds. Folding avoids putting more chips in with a dominated offsuit hand.
