Hold'em table

Suited connector 56s on the button in a 3-handed game plays well in position; a standard 3x open applies pressure and can win the blinds or build a pot with a hand that flops well.

J8 offsuit is weak out of position facing a 3bb raise with another player still to act; folding is best.

3-7 offsuit is too weak to continue against a button open, so folding is the highest-EV option.

8-6 offsuit from the button facing a raise isn't strong enough to continue; folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind. K8 offsuit is good enough to complete for 50 rather than fold, but not strong enough to build a pot out of position.

Pocket eights play well as a value raise against the limper; building the pot heads-up with a pair is profitable and isolates seat_3.

K8 offsuit is too weak to continue out of position against a 3bb raise; it is dominated by much of a big-blind raising range and does not have the equity or playability to call.

AKo is a premium hand on the button, so I open-raise to 3x the big blind to build the pot and take the initiative.

AKo is a premium hand and I'm out of position as SB, so I 3-bet for value and to build a pot heads-up rather than call and play a bloated pot multiway.

Facing a raise and reraise to 900 with 68s out of position, this is too weak to continue profitably.

AKo is ahead of a typical small-blind 3-bet range and plays well as a 4-bet in position. Raising to 2400 applies pressure while keeping stacks deep enough to continue if called.

With AKo I only need ~31% equity to call 1500 into a 3400 pot, and AKo retains roughly 40% even against a strong 4-bet range like QQ+/AK. Shoving would fold out worse hands and get called only where I'm an underdog, so calling keeps my equity and postflop options.

I hold top pair top kicker after a 4-bet preflop; checking keeps the pot controlled against a range of QQ+/AK where I'm only ahead of AQ/KK and chopping AK, while avoiding bloating the pot out of position.

I have top pair, top kicker on a dry ace-high flop in a low-SPR 4-bet pot. A half-pot value bet gets called by worse pairs and sets up a turn shove.

Queen-seven suited is playable from the button in a 3-handed game, and a standard 3x open applies pressure on both blinds while keeping position postflop.

K6o is too weak and dominated to continue out of position against a 3x button open; the price does not justify the poor postflop playability.

Button raise with Ace-high offsuit is a standard steal attempt against two blinds.

T3 suited is too weak to continue out of position against a button open, so folding is the highest-EV option.

Q9o is playable in position three-handed, so I open to 2.5bb rather than limp or fold a hand that can take the pot down or realize equity on the button.

T9 offsuit out of position against a button raise is a marginal spot; folding avoids playing a dominated, hard-to-play hand without position.

Weak offsuit 5-2 facing a raise; not worth calling even from BB.
