Hold'em table

Opening from the button with A10o to 2.5x BB is standard GTO strategy in 3-handed play.

5-3 offsuit is one of the worst starting hands and I'd be calling 200 more out of position against a button raise with the big blind still to act. Folding is clearly the highest-EV play.

K6 offsuit is too weak to defend the big blind against a button open; folding avoids a dominated, poorly connected hand out of position.

23o is too weak to complete or raise from the small blind even heads-up; folding avoids putting more chips in with a hand that rarely flops well.

K2o is too weak and poorly connected to open from the button; folding avoids dominated spots and difficult postflop play.

In a blind-versus-blind scenario with the button folded, pocket fours have plenty of equity to raise for value and fold equity against the big blind.

Q2o is dominated by the opener's 3x raise range; calling 200 to play a weak out-of-position hand is not worth it.

53s is too weak to open profitably even from the button in a 3-handed game.

AKo is a premium hand heads-up against the big blind; a 3x raise builds the pot for value while retaining fold equity and denying the BB a cheap flop.

A5s has enough equity and playability in position against a small-blind open to continue; calling keeps the pot manageable and realizes suited-ace equity.

I have top pair top kicker after raising preflop against a single caller; betting around 70% of pot builds value while charging draws like flush or straight combos.

Ace-high with no pair and no real draw on K97 is too weak to continue against a flop bet.

King-four offsuit is too weak to play even from the button against two random hands; folding is clearly best.

Button folded, so this is heads-up versus the big blind with suited ace-eight. A small raise to 300 takes the initiative and builds the pot with a hand that plays well postflop.

KQo has great equity and plays well in position against a standard small blind opening range. Calling closes the preflop action at attractive pot odds.

I have middle pair with an ace kicker on a dry board and am first to act. A small one-third-pot c-bet gets value from worse pairs and overcards while keeping the pot manageable out of position.

Getting 4-to-1 pot odds in position against a 1/3 pot c-bet, KQo has sufficient overcard and backdoor equity to float.

I have only a weak pair of eights with an ace kicker, and the queen is a scare card that improves much of the caller's range. Checking controls the pot and avoids betting into a likely better hand.

Turn brings top pair with a king kicker after our flop float. Betting 60% pot for value against draws, middle pairs, and worse queens.

Middle pair with an ace kicker is too weak out of position against a 60% pot turn bet on a queen. I am often behind and will face a difficult river, so folding is best.

93o is too weak to open even on the button in a three-handed game, so folding is the highest-EV option.

King-Jack suited is a premium holding in a blind-versus-blind battle; raising to 3bb builds the pot and exerts positional pressure.

K6o in the big blind vs a small-blind 3x raise is a marginal but profitable defend at these pot odds (need ~33%, hand has ~37-40% equity vs a wide SB range), and I act last postflop since the button folded.

This low, connected flop heavily favors the big blind's defending range, so checking our overcards out of position is standard.

My 6h makes trip sixes on this flop, a very strong but vulnerable hand that wants to build the pot immediately against seat_1's range. Betting around two-thirds of the pot extracts value from pocket pairs and draws like the diamond flush.

I completely missed this low, connected flop with King-Jack suited and lack sufficient equity or position to continue facing a two-thirds pot bet.
