Hold'em table

A3 offsuit is a profitable button open three-handed. A 2.5 big-blind raise applies pressure while keeping the pot manageable.

In 3-handed play, A9o has solid equity and an Ace blocker against a wide button opening range. 3-betting puts pressure on the button and prevents the big blind from easily entering the pot.

6c5s is weak facing a button open and a small blind 3-bet, and calling 750 more out of position against two ranges is unprofitable, so I fold.

A3 offsuit plays poorly against a sizable three-bet, even with position. Folding avoids investing more with a frequently dominated hand.

T3o is too weak to open even from the button in a 3-handed game.

A7s is a strong hand in a 3-handed pot; with the button folded, raising from the small blind against the big blind is profitable and builds the pot with a good hand.

With 8-4 suited, calling 200 closes the action preflop and lets me play in position against the small blind.

Ace-high with a gutshot (8 makes 5-6-7-9 straight... actually 7-6-5 plus 9 needs an 8) and backdoor flush draw, heads-up in position-less spot as preflop raiser; a value/semi-bluff bet of about two-thirds pot builds the pot and denies equity.

The gutshot straight draw and backdoor spade draw give me enough equity to call this flop bet, especially with position.

I have the nut flush draw (As with 7s... actually spades: only As, 7s, 6s on board = three spades? no) so correction: I hold a gutshot-plus-pair-less hand with A-high, 7 gives open-ended-ish draw 5-6-7 with 9 needing 8 for a straight, plus overcard ace. Betting about half pot as a semi-bluff with a straight draw and backdoor equity is reasonable heads up.}

A 3 or 7 can complete my straight. The turn price is too steep on direct odds alone, but position and the chance of winning more chips on a favorable river make a call reasonable.

I hold ace-high with a missed straight draw on a 6-9-5-2-J board. Seat_1 called flop and turn, so it likely has a pair or a draw, and ace-high has some showdown value but can't profitably bet for value. A bluff into a range that called twice is unlikely to work, so I check.

Eight-high has almost no showdown value. After the opponent checks the river, a bet can represent a made hand and may fold out missed draws or weak pairs.

I hold only ace-high on a board with no pair. Calling 1900 into 4700 needs about 29% equity. The opponent's call-call-then-bet line is mostly value hands, with too few bluffs for ace-high to beat, so I fold.

QQ is a premium hand on the button in 3-handed play, so I raise to 3bb for value and to build the pot against the blinds.

4♠2♠ is too weak to defend from the small blind against a 3× button raise, especially with the big blind still to act.

Holding 8c 4d facing a button open to 3bb, this hand is too weak to defend out of position.

Nine-five offsuit is too weak to open profitably against both blinds at this stack depth.

T6o is too weak to complete or raise from the small blind out of position.

96o is too weak to open from the button even in 3-handed play.

6-3 offsuit is one of the weakest hands. Completing the small blind for 50 more would leave me out of position with a hand that plays poorly, so I fold and lose only the 50 already posted.

Pocket sixes on the button in a 3-handed game is a strong hand, so raising to 3bb for value and position is better than limping or folding.

Nine-deuce offsuit is too weak to defend the small blind against a three-big-blind raise, especially with the big blind still to act.

J5o is too weak to defend against a 3x button open out of position.
