Hold'em table

7-3 offsuit is too weak to profitably enter from the button, even in a three-handed game.

ATo is strong heads-up against only the big blind after the button folded; a standard 3x raise builds the pot with a good equity hand and applies pressure to weaker holdings.

Getting 2:1 pot odds in position against a blind-versus-blind open, QTo is a clear defend.

I have top pair top kicker on an A-high flop after my preflop raise; a ~2/3-pot continuation bet builds the pot against the BB's calling range while charging draws like gutshots and flush draws.

Holding just a gutshot straight draw with Queen-high on an Ace-high board facing a 2/3 pot bet, the pot odds do not justify calling.

Pocket sixes is a profitable button open 3-handed; raising to 3x builds the pot with position and applies pressure on both blinds.

Holding 3d 2s from the small blind against a button raise is an easy and standard fold.

T4 offsuit is too weak to defend against a 3x button raise, even with the big blind discount.

T2s is too weak to open even from the button in a 3-handed game.

K5 suited is playable heads-up from the small blind, and calling keeps the pot small with a hand that can make strong draws.

I'm in the big blind with 52o facing a limp; checking is free and lets me see a flop or fold cheaply if the SB raises.

Semi-bluff with a strong king-high flush draw and some overcard equity; a modest bet can win the pot now while building it when called.

I hold 5d2c with no pair, no draw, and no showdown value on Ts-8h-6h; calling 125 into a small pot with the worst hand is a clear fold.

On the button, 9♥3♥ is playable as a wide opening hand with position and suited potential. Raising small applies pressure to the blinds while keeping the pot manageable.

T7 offsuit is far too weak to defend the small blind out of position against a button raise, especially with the big blind still to act. Folding saves 200 chips with a hand that has poor equity and playability.

Q2o is too weak to defend out of position against a 2.5x button open.

J6o is too weak to complete or raise out of position against the big blind.

A5s is a strong suited ace with great playability on the button, making a standard 2.5bb opening raise the optimal play.

9♠5♣ is a weak, disconnected hand and I would be out of position against the raiser with the big blind still to act. Fold rather than invest more from the small blind.

Eight-two suited is far too weak to defend against a 2.5x button raise even with pot odds; dominated when connected and rarely makes a winning hand.
