Hold'em table

Q8o is playable as a button open in three-handed poker, so I raise to 2.5bb to take the initiative rather than flat-calling a weak offsuit hand.

7-2 suited is among the worst starting hands; facing a 2.5x button open from the big blind, folding is clearly correct despite the suited discount.

J6 suited is a speculative hand; calling 1bb from the button to see a cheap flop in a 3-handed pot is reasonable.

7-2 suited is the weakest hand in the deck; even at 5-to-1 pot odds from the small blind, playing out of position against two players with this hand is a losing proposition.

96s is too weak to raise out of position against a button limp, and checking is free, so I take the flop.

Nine-six offsuit completely misses this monotone flop and has no pair or draw, so checking is the disciplined play out of position in a limped pot.

I already have a flush (Jd/6d plus three diamonds on board), so I should bet for value against a checking opponent.

9c6c has no pair, no flush draw, and no straight draw on a monotone diamond flop, so calling 175 is burning chips.

K8o on the button in a 3-handed game is a standard open; raising to 2.5bb takes initiative against the blinds.

J5o is too weak to defend out of position against a button open; folding saves chips.

J6o is weak out of position against a button raise; not worth calling 150 more.

K5 offsuit is too weak and poorly connected to open or limp from the button, so folding preserves chips.

5-7 offsuit is weak and I'd be out of position heads-up against BB; not worth defending.

A5 suited is a decent speculative hand; raising from the button isolates blinds and builds a pot in position.

J7 offsuit in the small blind facing a 3x button open is a clear fold; it plays poorly out of position and is dominated by much of the raiser's range.

75 offsuit is too weak to continue out of position against a button open, so folding is the highest-EV option.

54o on the button in a 3-handed game is a marginal hand, but a small open-raise to 2.5bb from the button with position is standard; folding to a 3-bet is fine.

K7 offsuit is too weak to continue out of position against a button open, so folding the small blind is the highest-EV line.

9h4h offsuit-ish weak hand facing a raise from button; not worth calling out of position.
