Hold'em table

Open-raising 2.5bb on the button with A5s, a standard strong suited ace opening hand.

92 suited from the small blind facing a 2.5x button open, with the big blind still to act, is too weak to call or 3-bet profitably out of position.

73 suited is too weak to continue out of position against a preflop raise, so folding preserves chips.

A3o is a clear open from the button in a 3-handed game, so I'm raising to 2.5bb to take the initiative and pressure the blinds.

T5o is too weak to continue out of position against a button raise with the big blind still to act.

Defending ATo in the big blind against a 2.5bb button open getting attractive pot odds.

As the out-of-position preflop caller on a dry king-high board, checking my entire range to the original raiser is standard.

A K-high dry board favors the button raiser's range, and A3 has a gutshot (5 for a wheel) plus ace-high overcard equity. A small c-bet of about a third of the pot is a profitable stab against the big blind's check.

Facing a flop continuation bet out of position on a dry King-high board with Ace-high and limited backdoors, folding is standard.

A4o is playable on the button three-handed; a small open applies pressure and can take the pot down or continue with the ace.

T6o is too weak to defend out of position from the small blind against a button open.

KTo in the big blind facing a 2.5bb button open in 3-handed play is well ahead of a wide button range, and the pot odds (150 to win 400) make calling clearly profitable. Calling keeps the opener's weaker hands in the pot, while 3-betting would mostly fold them out.

KT on a paired 7-9-7 board gives us overcards and a gutshot, and we are out of position against the preflop raiser. Checking keeps the pot small and lets us realize equity; we can continue against a small c-bet.

Ace-high has little equity on this paired board and no draw, so checking back controls the pot and preserves showdown value against a BB caller.

The button checked back the flop, which caps their range with many unpaired overcards. A turn probe of about half pot can fold out better high-card hands, while my king-high has little showdown value if I check.

Ace-high with no pair or draw on a paired board; the turn bet is not worth calling with this hand.

K6o is slightly too weak to open profitably from the button even in 3-handed play, making a fold standard.

Small pair in a blind-vs-blind spot after the button folded is a clear open; raising to 3bb takes initiative and can win the blinds outright.

A3o is too weak to continue against a 3bb small-blind raise; it realizes poorly and is not worth a call or 3-bet.

In 3-handed play, 65o on the button is a reasonable steal candidate against two blinds. A small open to 2.5bb puts pressure on them while keeping the risk low.

A4o is too weak to call a button open out of position, and it is a poor three-bet bluff with a weak kicker and the big blind still to act.

T2o is far too weak to defend out of position against a button raise.

93o is too weak to call or raise even on the button in a three-handed pot; folding avoids investing chips with a dominated, disconnected hand.

K3o is too weak to complete or raise from the small blind out of position against the big blind.
