Hold'em table

9h4s is too weak to continue facing a full big blind, especially with only three players and poor playability.

Button folded, so it's SB vs BB heads-up with K6o; this is a standard open-raise spot from the small blind against a single opponent, taking initiative rather than limping or folding.

Calling costs 200 to contest a 600-chip pot, and 54 suited has good playability against a small-blind opening range. Position and 100bb starting stacks support defending rather than folding or inflating the pot.

As the preflop raiser on a dry T82 rainbow board, a small range c-bet with K-high and some equity vs the BB's calling range is standard; it folds out many overcards and worse hands cheaply.

Five-high with only backdoor draws has too little equity to continue comfortably, even against this small bet. Without a read that favors bluff-raising, folding is the best option.

On the button in a 3-handed game, 65o is a marginal but playable steal hand; a 2.5x open puts pressure on both blinds and has decent playability postflop in position.

Pocket eights are strong enough to three-bet against a wide button opening range. Raising discourages the big blind from entering and denies equity while taking the initiative out of position.

43o is the worst possible holding facing a 3-bet to 1000 with only 900 to call; I have no equity and terrible implied odds, so folding is clearly correct.

65o facing a 4x 3-bet from the small blind out of position is a clear fold; poor equity and weak playability for 750 more.

75 suited is a profitable button open three-handed, combining blind-steal potential with good postflop playability. Raising to 2.5 big blinds applies pressure while keeping the investment modest.

T2s is too weak to defend out of position against a button raise, especially with only 200 chips to call and poor playability. Folding preserves chips for better spots.

J6 offsuit is a weak hand out of position against a button open; folding is standard even at these pot odds.

Three-handed on the button, raising applies pressure and takes initiative with position rather than calling weakly with a marginal connector.

7s6s suited connector in the small blind facing a 3x button open with a BB still to act; out of position with 100bb, this is a marginal hand that plays poorly OOP, so folding is the standard, chip-preserving play.

K4 offsuit is too weak to defend profitably against a 3bb button open without evidence of an unusually wide opening range. Playing out of position with poor connectivity and a frequently dominated king favors folding.

AJo on the button in a 3-handed game is a clear open-raise; standard 2.5x sizing to take initiative against the blinds.

KQo is strong against a typical button opening range and blocks several premium hands. A sizable three-bet discourages the big blind from entering and compensates for playing out of position.

4c9c is too weak to call a 3-bet for 1000 chips out of position; folding avoids bleeding chips with a dominated hand.

AJo in position 3-handed is too strong to fold to a single 3-bet from the SB, whose range here should be fairly wide; calling with position keeps the pot manageable and avoids bloating it against a dominating 4-bet range.

Top pair with a strong kicker is a good value bet on this king-high flop, which favors my preflop three-betting range. A roughly one-third-pot bet can get calls from weaker kings, pocket pairs, and heart draws.

AJo with no pair and no draw on a K-high board facing a c-bet from a 3-bettor whose range is heavy with AK/KK/AA/QQ; ace-high with no equity backup is a clear fold.

96 offsuit is below a standard button opening range, with weak connectivity and poor high-card value. Without evidence that the blinds overfold, folding is preferable to limping or raising.

Raising to 300 to apply pressure and take initiative with a speculative hand; the button folded, making this a heads-up pot where aggression is often profitable.

2-3 offsuit is among the worst starting hands; facing a 3x raise from the small blind out of position, folding is clearly correct despite decent pot odds.
