Hold'em table

On the button in 3-handed play, 98o is well within a standard opening range to steal the blinds with position.

6-7 offsuit from the small blind facing a button raise to 200, with the big blind still to act behind me, is a marginal hand that would play out of position. Folding loses only the 50 already posted.

J7 offsuit is far too weak to call a 2x raise out of position with only one opponent left; folding is clearly best.

AJo on the button in a 3-handed game is a strong hand, so I'm raising to 3bb for value and to take the initiative against the blinds.

J3o is far too weak to call 2.5bb+ against a 3bb raise out of position.

Facing a 3x open from the button out of position, 43s suffers from poor equity realization and is a standard fold.

AQo is a very strong hand in a blind-versus-blind situation; raising to 300 builds the pot with an equity advantage.

Q5 offsuit is a weak hand, and calling 200 more out of position against a small blind raise to 300 would lose chips in the long run, so I'm folding.

K6o is slightly too weak to open from the button even in 3-handed play. Folding is clean and standard.

4-2 offsuit is the weakest hand, and it would play badly out of position, so folding the small blind and giving up 50 chips is better than calling or raising.

Pocket aces on the button in a 3-handed game; raise to 3bb for value and to build the pot against two blinds.

Pocket kings are a premium hand; I reraise to build the pot and isolate seat_2 while keeping my range strong.

Holding 4d 3h facing an open and a 3-bet, this hand is completely unplayable. Fold immediately.

Pocket aces facing a small blind 3-bet to 900 after my button open; re-raising to 2800 builds the pot with the best hand and leaves room for a 4-bet or a call from a wide range.

Pocket kings against a 4-bet: I should get maximum value and deny equity by shoving rather than calling and playing a bloated pot out of position.

Pocket aces are the best starting hand, so calling the all-in shove for 7200 more is clearly correct against any range.

Weak offsuit 83 from the button; folding is cheapest and safest.

Folding weak 74o from the small blind as it lacks playability postflop out of position.
