Hold'em table

QTo is a solid opening hand from the button 3-handed; a standard 3bb raise builds the pot with position and applies pressure on the blinds.

K-2 offsuit is too weak to continue from the small blind against a button raise, especially with the big blind still to act.

54o is too weak to defend out of position against a 3bb open.

Q9 offsuit is strong enough to open from the button three-handed. A modest raise builds the pot and applies pressure to the blinds.

AKs is a premium hand that wants to build the pot and take initiative from out of position via a 3-bet against a button open.

J5s has far too little equity to call 900 into a raise-and-reraise pot; I'd need roughly 40% equity and this hand won't come close against two aggressive ranges.

Q9 offsuit is too weak to continue against this large preflop 3-bet, even with position and deep stacks.

84o is too weak to open from the button, even in 3-handed play.

KJs is a strong premium hand three-handed, and I'm on the button with position postflop. A standard 3x open builds the pot while retaining initiative.

K♦9♦ is a playable suited hand against a button open, but calling avoids inflating the pot out of position with a marginal hand.

Closing the action with pocket eights getting over 4.5:1 pot odds is an easy call to set-mine and see a flop.

I have only a gutshot straight draw and a backdoor flush draw, with two opponents in the pot. I’ll check rather than lead into the preflop raiser and caller.

Holding third pair on a broadway-heavy flop in a multiway pot with the preflop raiser yet to act, checking is standard.

I have top pair with a strong kicker as the preflop raiser, and both opponents checked, so a half-pot bet extracts value from jacks, queens-draws, and weaker pairs while charging draws.

The bet is sizable, but K♦9♦ has a gutshot to the nut straight plus backdoor flush potential and overcard equity. Calling is preferable to raising with this draw, especially with another player still in the hand.

Holding an underpair to both broadway cards facing a bet and a call leaves us with negligible equity and poor playability.

I have a pair with a gutshot, so checking keeps the pot manageable and lets me see whether the button acts before committing more chips.

I only have top pair jacks with a king kicker, and the 9c completes T8 straights while QJ/JT/sets beat me, so checking back for pot control against a check-call line is best; I can call a small river bet or fold to big pressure.

My pair of nines has some showdown value, but the flop caller may have a jack or queen that beats it, and worse hands are unlikely to call a river bet. I’ll take the free showdown.

Top pair with the second-best kicker; a modest river bet extracts value from worse jacks, nines, and missed draws while staying cheap if raised. Checking back is safe but leaves chips on the table against their capped checking range.

My river pair of nines is weak on a board with both queens and jacks, and the bet follows a flop c-bet and turn check. I’m unlikely to beat enough of the opponent’s value range to justify calling.

A♠? Ah-Jd is a strong button hand in a three-handed game, so I’m opening for value with a standard 2.5× big blind raise.

Q2s is too weak to defend out of position from the small blind against a button open.

T7o is dominated by most of a button's raising range and plays poorly out of position postflop; calling 150 more for a weak, hard-to-realize hand is -EV, so folding is cheapest.

43o is well outside any reasonable opening range on the button in 3-handed play. Easy fold.
