Hold'em table

94 offsuit is too weak to open from the button in 3-handed play against two blinds at 100bb; folding is standard.

J2 offsuit is a weak hand out of position heads-up against the big blind. Calling 50 more is marginal, but the hand plays poorly and folding is the simplest choice.

Q5s is a marginal hand. On the button against two blinds, calling 100 into a 150 pot is close, but the hand plays poorly out of position postflop and is dominated often. I'm folding to avoid a marginal spot.

7-4 offsuit is a weak hand out of position against the big blind; folding the small blind is the standard play here.

9-4 offsuit is a weak hand even on the button in 3-handed play; folding avoids losing chips with a dominated holding.

AQo is a strong hand blind vs blind, so I'm raising to 3bb for value and initiative.

8-4 offsuit is a weak hand, and calling 200 more out of position against a small-blind raise to 300 is a losing play, so I'm folding.

Q9o is a standard open from the button in 3-handed play; a 2.5bb raise steals the blinds often and plays well in position.

T6 suited from the small blind facing a button raise to 250 with a big blind still to act behind is a marginal hand that plays poorly out of position, so I fold rather than pay 200 more.

A8 suited in the big blind facing a button open in 3-handed play is a strong hand; 3-betting to isolate and take initiative is a reasonable play versus a wide button range. Alternatively calling is fine, but a 3-bet to 8bb builds the pot with position disadvantage mitigated by fold equity.

Q9o is near the bottom of a button opening range and plays poorly against a BB 3-bet to 8bb, especially facing dominating hands. Calling 550 to win a 1100 pot isn't justified given we'd be out of position equity-wise with a weak, easily dominated hand.

Pocket kings on the button in a 3-handed game is a premium hand, so I raise to 3.5bb for value and to build the pot against the two blinds.

T4 offsuit from the small blind facing a 3.5x button open is a clear fold; it plays poorly out of position and is well behind an opening range.

KTo in the big blind facing a 3.5x button open in 3-handed play is well ahead of the button's wide range, and we get 250 to win 600. Calling realizes equity fine, while a 3-bet would mostly fold out worse hands.

With an open-ended straight draw out of position on a paired board that favors the preflop raiser, checking keeps the pot controlled and lets me check-call or check-raise depending on the button's sizing.

Pocket kings on a J-J-Q board is a strong hand that beats most of what the big blind could hold. I'm betting about two-thirds of the 750 pot for value, and a smaller size should keep worse pairs and draws in.

KT on JJQ gives an open-ended straight draw (any A or 9) plus a king overcard, facing a small c-bet of 500 into 750. Calling gets 3.5:1 on the price, keeps the pot controlled, and lets us realize our equity against the button's wide range.

I have an open-ended straight draw (any A or 9) plus king overcard outs, out of position on a paired board. Checking keeps the pot controlled and lets me realize my equity, with a call likely against a reasonable bet.

I hold KK on a J-J-Q-2 board, which is a strong hand that beats most of seat_1's range. Seat_1 has only called and checked, so they are likely weak or holding a draw or a jack. A bet of about half the pot (900 into 1750) gets value from queens, jacks and draws, and it won't commit my stack against a hand that beats me.

Open-ended straight draw (A or 9) gives about 17% raw equity against needing 25%, but deep stacks provide implied odds and a king may sometimes be good, so calling beats folding or raising.

The missed straight draw has little showdown value. After calling twice, a river lead credibly represents a slowplayed jack and can fold out queens and pocket pairs, and the king blocks KQ and KJ.

Kings full of nothing but two pair, kings and jacks, beats many check-calling hands like Qx, Ax and mid pairs, and the price of 2400 into 5950 needs only about 29% equity. A raise would only get called by Jx or full houses that beat us.

A5o on the button in a 3-handed game is a standard open; raising to 2.5bb takes initiative and pressures the blinds.

QQ is well ahead of a button opening range; 3-bet out of position to build the pot and deny equity, sizing around 4x.

7c Td is a weak offsuit hand facing a button open and a small-blind 3-bet to 1000 with a call of 900 more needed. Folding is clearly better than calling out of position against two ranges.

A5o facing a 4x 3-bet from the small blind plays poorly postflop and is dominated by most 3-betting ranges; folding avoids a marginal spot rather than bluff-4-betting into an unknown opponent.
