Hold'em table

42o is well outside any reasonable opening range on the button, making an easy fold.

Heads-up after the button folds, J9o has solid equity and I only need 50 to complete into a 150 pot, giving excellent odds to see a flop in position-neutral play.

Pocket nines are well ahead of a small-blind limp; raise for value and to take initiative heads-up.

J9o is far too weak to call a 4x raise out of position; I'd need ~37% equity against a strong range and this hand plays poorly postflop. Folding is clearly best.

Pocket sevens play well from the button; a standard 3x open builds the pot with a solid pair while retaining position and fold equity.

7♠6♥ offsuit is too weak to call a 3bb button raise from the small blind, especially out of position with the big blind still to act.

Getting 2.25:1 pot odds against a button open in a 3-handed game, defending T9o in the big blind is standard.

I missed the flop completely from out of position and check to the preflop aggressor.

My 77 is an overpair to the 2-6-5 flop, so I bet for value and protection against overcard turns after the BB check-calls preflop. A ~60% pot continuation bet keeps worse pairs and draws in while building the pot.

I completely missed this low board with ten-high and no direct draw, making an easy fold facing a flop continuation bet.

Q2 offsuit is weak, but from the button in a three-handed pot an unopened steal raise is reasonable. A small raise puts pressure on both blinds while limiting the risk.

Folding J9o from the small blind against a button open, as it plays poorly out of position and with the big blind still to act.

Seven-two offsuit is the worst starting hand and I'm facing a 2.5x raise out of position with no fold equity concerns; calling 150 more to chase a weak hand is -EV.

K5o is slightly too weak to open profitably from the button even in 3-handed play.

Pocket eights on the button play well as a small open-raise for value and position; 3x applies standard pressure without committing the stack.

9♥2♦ is too weak to defend against a button raise, especially with the big blind still to act.

A4o plays poorly out of position facing a 3x open from the button, making it a standard fold.

J3 suited is a reasonable button open in a three-handed game, and raising lets me apply pressure rather than limp.

Folding J5s from the small blind against a button open as it is too weak to continue out of position.

6-8 offsuit is a weak hand facing a 2.5x button raise heads-up; folding avoids playing a dominated, hard-to-play hand out of position for 150 more chips.
