Hold'em table

Heads-up in the SB versus the BB, A4o is well ahead of a random hand, so a standard 3x open is the right play.

Jack-ten suited has strong playability heads-up against a small-blind open, and calling preserves their weaker holdings while realizing equity in position after the flop.

Top two pair on a spade-draw board, out of position against the big blind; betting about two-thirds pot gets value from aces and draws while charging the flush draw.

We have only jack-high with no made draw on an ace-high, two-spade board. Folding avoids continuing against the preflop raiser's flop bet with very weak equity.

Q2 offsuit is a marginal-to-weak button open in 3-handed play with two players left to act, and folding is the low-risk standard choice here. It's close, but I'd rather avoid being dominated.

JTs is a strong heads-up blind-versus-blind hand with good playability. Raising applies pressure and builds a pot with a range advantage.

Q2 offsuit is a weak button open in this setup; folding avoids entering a marginal pot.

7-5 offsuit is too weak to invest against two opponents, so I fold and preserve my stack.

Blind vs blind after a button fold, J6o is a playable steal. Raising to 3bb puts pressure on the big blind's wide defending range.

Q5 offsuit is a weak big-blind defense against a small-blind raise, with poor playability out of position.

Three-handed on the button, 74s is at the bottom of a wide opening range, so a small open to 2.5bb puts pressure on the blinds, and the hand plays well postflop when called.Three-handed on the button, 74s is at the bottom of a wide opening range. A small open to 2.5bb pressures the blinds, and suited connectors play well postflop when called.

A2o is difficult to realize equity with out of position, but the ace blocker makes it a suitable squeeze bluff against the button open and the blind behind.

My hand is very weak (4-6 offsuit) and I'm facing a raise and a re-raise, so calling more chips is not profitable. I'll fold and preserve my stack.

74s is too weak to continue profitably against a 3.6x small-blind 3-bet, even with position. We would be calling 650 chips to win 1900, and too often we would miss or be dominated.

8-3 offsuit is a very weak button hand and not worth entering with at this stack depth.

2d4s is a very weak hand out of position against the big blind, and calling offers poor postflop playability despite the pot odds. Folding minimizes loss with little upside.
