Hold'em table

J8o is on the fringe of the button opening range in 3-handed play; folding avoids playing a weak offsuit holding out of position against 3-bets or multiway.

AKo on the button is a premium raising hand; a standard 3x open builds the pot and applies pressure on the blinds.

75o is too weak to continue out of position against a button open; folding avoids putting more chips in with a dominated hand.

Getting attractive pot odds of 200 to win 450, QJo is a standard BB defend against a button open.

Check to the preflop raiser out of position with Queen-high and backdoor draws.

I flopped top pair top kicker with AK on a two-tone board after raising preflop; betting ~70% pot extracts value from weaker kings and pairs while charging spade and straight draws.

I only have Queen-high with a backdoor flush draw and no immediate straight or pair equity against a large flop c-bet.

95 suited is too weak and poorly connected to open first-in, even on the button; folding avoids investing chips with a dominated hand.

82s is too weak to profitably complete or open-raise out of position, making an easy fold.

54 offsuit is too weak to open profitably from the button. Folding to conserve chips.

43 offsuit out of position against the big blind is too weak to complete even for half a bet; folding preserves chips for better spots.

King-seven offsuit is a marginal but playable button open three-handed; raising to 2.5x applies pressure on the blinds and builds the pot with position.

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

A3o plays poorly out of position facing a 2.5bb button open, suffering from severe reverse implied odds.

Ace-eight offsuit is a clear button open in three-handed play. A raise to 300 takes the initiative and builds the pot with a hand that plays well against blinds.

K3s is too weak to defend out of position against a 3bb open from the button with the big blind left to act.

K7o has decent showdown value against a 3x open, and calling keeps the pot small out of position; the hand is likely a bit behind but has equity and position disadvantages make folding tight.

I flopped trip sevens (only 7d beats me), so I'll check to the preflop raiser planning to check-raise or let them bluff, building a bigger pot than a lead would.

Ace-high with no pair or real draw on a paired board has little reason to build a pot after the check. Checking keeps the pot small and preserves showdown value.

My 7c makes trip sevens with an ace kicker; only AA, 77, or A7 beat me, and the turn ace smashes a preflop-raiser's Ax-heavy continuing range. Betting ~pot builds value while leaving room to raise if they come back over the top.

I have aces and sevens, which chops with most lone aces and beats bluffs, while a raise mostly gets called by sevens and tens that beat me. Calling 600 into 1250 is the right price to keep their weaker hands in.

I hold trip sevens with the top kicker (777AK) on T77A2, so I'm betting about half pot for value against ace-one-pair hands and underpairs; if seat_3 raises, that almost always means a full house or quads and I can release.

Getting nearly 3:1 to call 1000 into 2850, I only need about 26% equity with aces and sevens. Seat 2's turn-river line is strong, but the smaller river bet still includes enough missed broadways and bluffs for a call to be profitable.
