Hold'em table

J7s is suited and playable as a button open in three-handed play, so I raise to 3bb rather than limp or fold.

7-2 offsuit is far too weak to defend from the small blind against a button 3x open, especially with the big blind still to act.

72o is dominated against a 3bb raise; folding is clearly best.

J7 offsuit is a reasonable button open in three-handed play, leveraging position and initiative. I use a modest sizing to keep weaker hands and blinds under pressure.

T5s is too weak to continue out of position against a button raise; folding avoids a dominated, low-equity spot.

5h7s offsuit is a weak hand from the button facing two players; folding is the profitable play.

Pocket eights are ahead of the big blind's range heads-up after the button folds, so I raise to 300 for value and fold equity rather than just completing.

Q3 suited has sufficient heads-up equity and playability to defend the big blind against this small blind open.

Pocket eights are an underpair on an ace-jack flop that favors the preflop caller, so I check to control the pot rather than bluff into a strong range.

The preflop raiser checked a coordinated ace-high flop, leaving many missed holdings in their range. A small stab can win the pot cheaply while preserving flexibility if they continue.

Pocket eights are an underpair on A-J-5, but the flop bet is only one-third pot, so the price is good enough to continue and see the turn.

Pocket eights are an underpair to the ace and the paired jacks, so there is no value in betting. Checking keeps the pot small and preserves a free showdown.

The paired turn is a strong bluff card after the flop check-call, and many small pairs or missed club draws will have difficulty continuing. A medium sizing pressures those hands while preserving chips if called.

Pocket eights are crushed by the paired jack-ace board and a second barrel; not enough equity to call 600.

Q8o is playable as a button open in three-handed poker, so I raise to 2.5bb rather than limp or fold a hand with decent steal equity.

5-3 offsuit is far too weak to defend from the small blind against an early 2.5bb open with the big blind still behind.

4d7d is a weak hand facing a 2.5x raise out of position; folding is clearly best.

Button open-raising 65 suited is preferable to folding and can profit from position against the blinds. The modest sizing keeps the risk controlled.

9-3 offsuit is dominated against a 2.5x raise; folding is clearly best.

J2 offsuit is too weak to call a button open from the big blind; folding is the clear choice.

Button folded, so this is blind versus blind. K7o is not strong enough to raise out of position, but 50 to call into 150 is the right price to see a flop.

With T4 offsuit in a limped heads-up pot, checking the big blind realizes equity without inflating the pot.

King-high with no pair or draw on a paired flop; checking keeps the pot small and realizes equity cheaply.

A small heads-up continuation bet can fold out unpaired overcards that currently beat our ten-high while risking little into the limped pot.

King-high with no pair and no draw on a paired board is too weak to continue against a flop bet. Folding avoids paying off a likely made hand or better king.
