Hold'em table

Q6o is too weak to open even from the button in a 3-handed game with no reads; it gets dominated too often, so folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind with J8o. A small raise takes the initiative and denies a cheap flop rather than completing.

Holding 8d 5s offsuit facing an SB raise to 3bb, this hand is too weak to defend profitably.

73o is too weak to open from the button; folding avoids a dominated, low-equity hand out of position postflop if called.

86o plays poorly out of position postflop against the big blind, making an easy fold.

Opening on the button with A8o at standard 2.25x sizing in 3-handed play.

42s is far too weak to call 175 more out of position against a button raise with the big blind still to act. Folding the trash hand preserves chips for better spots.

J4o is too weak to defend out of position against a button raise; folding preserves chips.

J9s is a standard button open 3-handed with 100bb stacks; raising builds a pot in position with decent equity and fold equity.

4-3 offsuit is too weak to continue out of position against a button raise, so folding preserves chips.

A7o is a standard defend in the big blind against a button open getting over 2:1 pot odds.

Check to the preflop aggressor out of position with Ace-high and no immediate made hand.

I have top pair (nines) as the preflop aggressor on a dry board, and the BB checked. A standard continuation bet of ~60% pot builds the pot for value and charges any draws like the diamond flush draw.

Holding only an ace-high with a gutshot straight draw out of position against a 60% pot c-bet, calling does not offer sufficient direct or implied odds.

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

97s is marginal out of position against a 2.5bb button open with the big blind left to act, so folding is standard.

AKs is a premium hand and the button's 2.5x open is likely wide, so I 3-bet for value and to build a pot while denying him a cheap flop.

J9o is too weak to continue against a 3-bet; calling is dominated and a 4-bet bluff has poor blockers and playability.

J2s is too weak to open profitably even on the button in 3-handed play.
