Hold'em table

Q6 offsuit is too weak to open from the button in a three-handed pot; folding avoids putting chips in with a poorly connected offsuit hand.

In the small blind heads-up against the big blind, J8o has sufficient equity and pot odds (calling 50 to win 150) to complete the blind.

I'm in the big blind with 5-8 offsuit and the small blind merely limped, so I get a free flop heads-up. Checking is clearly better than folding a free hand or raising such a weak holding out of position.

Check out of position with jack-high on a paired ace board against the big blind.

I hold 8-5 high on an AAx board with no draw, so my hand is effectively the board's pair of aces with weak kickers. Seat_2's limp-and-check line is passive; checking behind keeps the tiny pot cheap and lets me fold if they show aggression later.

Turned second pair after a checked flop; betting half-pot for value and protection against draws.

I hold 5-high with no draws on an Ad-As-Jh-2d board, so calling 100 into 300 requires equity I don't have, and bluff-raising into a turn bet on a paired-ace board is unprofitable. Folding is clearly best.

73o is well outside any reasonable 3-handed button opening range, making this a trivial fold.

Heads-up against the big blind, calling 50 into a 150 pot gives 3:1 odds, and 68o has roughly 40%+ equity vs a random hand, so completing cheaply is clearly +EV.

Ace-four offsuit is too weak to raise for value against the small blind's complete, and checking is free. I will see a flop and reassess.

I have bottom pair with a weak kicker on a coordinated board and can see a free card in position; checking keeps the pot small with a marginal hand.

Ace-high with no pair or draw has little showdown value, and the opponent checked, so taking a free card is better than bluffing into a dry board.

I have 6-high on a J-T-6-4 board with no draws; there is no value in betting and I don't want to build a pot out of position. Checking keeps the pot small and lets me fold cheaply if seat_1 shows aggression on the river.

Bottom pair with an ace kicker is too marginal to bet into a checked turn, so I check and keep the pot small.

My best line here is simply playing the board (ace-high), since even pairing my six yields a weaker hand than ace-high. With no value and little fold equity against a passive checking opponent, checking down is correct.

I have aces and fours on the river after a passive check-down, so I bet about three-quarters pot for value against worse pairs and two pair.

My 6-pair only beats pure bluffs, and a passive check-through player firing a small river bet more often holds Ax/Tx/broadway that beats me; folding saves 150 for a low-equity spot.

A3o is a standard open-raise from the button; I have position and can take the pot down or play a favorable postflop spot. Raising to 300 applies pressure on the blinds without overcommitting.

4s2s is too weak to continue against a button open; folding the small blind saves chips.

J4o is too weak to defend out of position against a 3x button open.

J9 suited is a solid button open in three-handed play, so I raise to 2.5bb to build the pot and apply pressure.

Holding 43o out of position against a button open is an easy standard fold.

On the button in 3-handed play, J9o is well within a standard opening range to steal the blinds and take position.

Suited 97 is far too weak to defend the small blind against a 2x raise with two players behind; folding loses the least.

AKs is a premium hand and the button opened to 2bb, so I 3-bet to 700 to build the pot and take the initiative heads-up.

J9o is too weak to defend against a 3-bet from the big blind, even in position.

Button in three-handed play allows a wide stealing range; J2s plays well as a cheap aggression spot since both blinds will usually miss flops.

3-2 offsuit is too weak to continue against a button raise, especially out of position as the small blind.

Q2o is far too weak to defend out of position against a 3x open.
