Hold'em table

Q5o is too weak to open profitably from the button even in a 3-handed game.

With the button folded, 6♥4♥ has enough equity and pot odds to complete the small blind heads-up. I’ll avoid inflating the pot with a weak hand.

I'm in the big blind with 8-9 offsuit and the small blind just limped, so checking is free and keeps a connected hand in a heads-up pot where I act last postflop. Raising this weak holding risks bloating the pot with little equity edge.

I have a weak bottom pair on a board with possible draws, so checking keeps the pot small and lets me see the next card without building the pot out of position.

I have middle pair (eights) on J-8-4 with two spades, and I'm last to act with the SB checking. A small half-pot bet charges draws and worse hands while keeping the pot manageable with a vulnerable kicker.

A small flop bet gives favorable pot odds, and my pair of fours can still be ahead of bluffs or weaker hands. I’ll call rather than inflate the pot with a marginal hand.

I have trips and can get value from Jx, pocket pairs, and flush draws while charging those draws. A modest turn bet keeps worse hands in and limits exposure to a better four or a slow-played hand.

6♣2♣ is too weak to continue from the button facing the big blind; folding avoids investing in a hand with poor playability.

AQo on the button 3-handed is a premium raising hand; I'll raise to 3x BB to build the pot and take initiative against the blinds.

Holding premium AKs in the small blind against a button open, raising for value out of position.

Q7 suited is too weak to continue against the small blind’s large three-bet, especially with the original raiser still to act.

Holding 52o on the button is well outside an opening range; folding is clearly optimal.

Q9 offsuit is strong enough to raise from the small blind against the big blind after the button folds. A raise to 300 applies pressure while keeping the pot manageable.

Getting 2:1 on a call (200 into 400) against a likely wide SB raise, and I'll have position postflop. T8o is marginal but the price and position make calling slightly better than folding.

A small continuation bet can pressure the big blind’s unpaired hands on this dry king-high flop. Q-high retains some backdoor equity, and the sizing limits risk.

I hold T-high with no real draw on a K-high board against a preflop raiser's continuation bet. Calling 200 into 800 with almost no equity is losing play, so folding is cheapest.

K5 offsuit is a reasonable button open in a three-handed game, and raising applies positional pressure while keeping the sizing modest.

2-6 offsuit is one of the worst starting hands, and I'm facing a 2.5x raise from the button with the big blind still to act. Calling 200 more with no equity, position, or fold equity is a clear losing play.

95o is too weak to defend from the big blind against a button open.

On the button 3-handed, A2o is a standard open-raise for fold equity and positional advantage; folding is too tight and limping surrenders initiative.

K6o is too weak to defend out of position against a button raise with the big blind still left to act.

J2 offsuit is too weak to defend out of position against a 3-big-blind raise, despite the pot odds.
