Hold'em table

24o is too weak to call or raise from the button against the blinds, so folding preserves the stack.

2d6s offsuit is the weakest possible button spot; calling 100 into a 150 pot with no fold equity leverage is unprofitable, so I fold and wait for a better hand.

Holding an unsuited weak hand 85o in the small blind, playing out of position against the big blind is unprofitable, so folding is the standard play.

Opening from the button with pocket queens for standard value.

AKo is a premium hand versus a button open, so I 3-bet to 900 to build the pot and take the initiative out of position.

72 offsuit is the worst hand and I face a 3-bet to 900; calling 800 to win 1250 with no equity or position is a clear fold.

Holding pocket queens on the button against a small blind three-bet in three-handed play is a clear spot to four-bet for value and protect our equity.

AKo is too strong to fold to a button 4-bet, and calling out of position leaves an awkward stack-to-pot ratio. Shoving realizes equity and folds out dominated hands.

In a 3-handed dynamic where I opened on the button and 4-bet, QQ has sufficient equity (roughly 40% against a standard 5-bet range of AA, KK, AK, and QQ) to justify calling 7,800 into a 12,300 pot offering roughly 38.8% required equity.

74s is playable as a button open in three-handed poker; a small raise takes the initiative and can win the blinds, and I can fold to a 3-bet.

5-2 offsuit is far too weak to defend the small blind against a 2.5x raise with the big blind still to act behind me.

Q6o is too weak to defend out of position against a 2.5bb button open.

K2o is weak, but on the button three-handed a small raise has strong fold equity against both blinds; 300 applies pressure while risking little if called.

Holding 95 offsuit out of position against a button open is a clear standard fold.

QTs is a strong blind defense against a button steal, and calling 200 into 450 is well priced with a hand that flops well.

Queen-ten has only a gutshot on an ace-jack flop and I am out of position against the preflop raiser, so checking is better than betting a weak draw.

I have king-high with no draw on an ace-high board against a preflop caller, so bluffing into a range full of aces, jacks, and pairs is thin. Checking back uses my position to realize free equity and reassess on the turn.

I have the nut straight (T-J-Q-K-A) on an unpaired board, so I bet for value before the river. A pot-sized-ish bet builds the pot while keeping worse hands in.

My pair of kings has a dominated kicker on a three-spade board; nearly every value hand in a preflop-raiser's turn-betting range (flushes, AK, better kings, two pair) beats me, and a bluff-raise has no equity when called. Folding is clearly cheapest.

Q3o is too weak to open even from the button in a 3-handed game.

82o is too weak to continue out of position heads-up; the extra 50 is not worth calling and a raise has little fold equity or backup equity.
