Hold'em table

4d2h is the weakest possible holding from the button in a 3-handed game; folding avoids investing chips with negligible equity.

J♦9♣ is playable heads-up from the small blind, and completing costs only 50 chips into a 150-chip pot. I’ll avoid inflating the pot out of position.

Pocket nines has a clear equity advantage against a blind-versus-blind limping range; raising to 4bb builds the pot and extracts value in position.

J9 offsuit is a weak hand out of position against a substantial preflop raise. The price to call is too high for its equity and playability.

With a playable pocket pair on the button in a three-handed pot, open-raise to build value and take initiative.

Folding 76 offsuit from the small blind against a button open as it lacks playability out of position.

T9o is a playable suited-connector-type hand with good implied odds heads-up; calling 150 into a 400 pot is cheap and keeps the pot small out of position.

I have 9-high with no pair or draw on 2-6-5, and the preflop aggressor likely has overcards; checking keeps the pot small and avoids investing more with a weak hand.

Make a small value-and-protection bet with an overpair, charging overcards and straight draws while keeping weaker pairs in the pot.

Ten-high with no pair on a 2-6-5 board facing a flop bet has little equity; not worth defending cheaply out of position heads-up.

Q2o is too weak to open raise or call even from the button in a 3-handed game.

J9s is a decent suited hand heads-up in position against only the BB; raising to 2.5x applies pressure and builds the pot with fold equity.

7-2 offsuit is far too weak to defend against a 2.5-big-blind raise, especially out of position. I’ll avoid investing more chips with a dominated hand.

King-high on the button in a 3-handed game is worth an open; I'll raise to 2.5x to apply pressure and take the initiative with position.

K7 offsuit is marginal but playable against a button open in a three-handed game, and calling keeps the pot manageable. I’ll avoid inflating the pot out of position with a 3-bet.

Holding T4o out of position against a button raise and a call from the small blind is an easy fold despite decent direct pot odds.

With middle pair and a king kicker on an ace-high flop, checking keeps the pot controlled and lets the preflop raiser act first.

I'm the preflop raiser in position on an ace-high flop; a half-pot continuation bet has good fold equity against a check-caller, and I retain a gutshot and king-overcard equity if called.

The small flop bet gives me favorable pot odds, and middle pair can still be ahead of bluffs or weaker hands. Raising would risk too much with a weak kicker.

I have a modest pair with a decent kicker, but the ace-high board and flop action make a value bet unattractive. I’ll take the free card and preserve showdown value.

I have two pair, aces and sevens, with a king kicker, which is a reasonable showdown hand. Betting risks getting called by better hands while worse hands may fold, so I’ll check.

My hand is just the board's pair of aces with a king kicker; any ace in villain's hand gives them trips, so a bet only gets called by hands that beat me or chop. Checking is free and best.

Pocket eights is a strong button hand three-handed, so raise for value and to take the initiative. A 2.5-big-blind open is a sensible size.

Holding 9h 2d out of position against a button raise is an easy standard fold.

A4o out of position is too weak to 3-bet for value but has decent equity against a button open; calling 150 more keeps the pot small and lets me play a suited-ace-free hand with position disadvantage but a strong kicker.

I flopped top two pair with A4 on A-3-4, so I bet for value against seat_2's preflop raiser, who likely holds a strong ace or overpair that will continue.

The sizable flop bet on an ace-high board is likely to have me beat, and pocket eights have little room to improve. I’ll avoid paying off a likely ace with only a bluff-catcher.

J3s is too weak to profitably open-raise from the button 3-handed. Folding is standard.
