Hold'em table

A5 suited is a clear open from the button in 3-handed play, so I'm raising to 2.5bb to take the initiative.

Nine-deuce suited is too weak to continue out of position against a button open, especially with the big blind still to act. Folding preserves the stack for better spots.

73s is too weak to defend out of position against a button raise, even with decent pot odds.

A3o is playable as a button open in three-handed play; a small raise builds the pot and takes the initiative rather than limping.

Holding T5o in the small blind facing a button open is an easy standard fold.

ATo is well ahead of a 3-handed button opening range, so a 3-bet for value and initiative works well; calling is also fine, but 3-betting to 10bb out of position plays better.

A3s is too weak and often dominated against a large BB 3-bet; folding avoids a marginal spot despite position.

A4o is well within the standard 3-handed button opening range, allowing us to steal the blinds or play in position postflop.

T6o from the small blind facing a button min-raise, with the big blind still to act, is a weak, dominated hand that plays poorly out of position. Folding is the standard play.

KTo has enough equity and pot odds to continue against a button open, and calling keeps the pot small out of position rather than bloating it with a weak offsuit three-bet.

King-ten high has no pair or draw on a paired flop, so I check for free rather than bluff into the preflop raiser.

Ace-high has decent showdown value and checking back controls the pot on a paired board that hits the big blind's defending range.

King-high with no draw on a paired board has thin showdown value and little fold equity worth paying for, so I check rather than turn it into a bluff.

I have Ace-high with reasonable showdown value after both players checked the flop. Checking back turn takes a free river card.

King-high has no showdown value on a paired ace-high board, but checking is free and betting would only fold out worse while getting called by any pair.

We spiked top pair on the river after checking through flop and turn, so we place a small value bet targeting weak pairs.

King-high has no pair and loses to every Ace or pair in the button's river betting range. The small bet is not cheap enough to bluff-catch with the bottom of my range.

K6o on the button in 3-handed play is a standard open; a 2.5bb raise steals the blinds often and plays fine in position.

Pocket threes have enough implied odds to set-mine against a 2.5bb button open, and a 3-bet would be too thin out of position.

A3o plays poorly out of position in a multiway pot with reverse implied odds, making it an easy fold despite decent pot odds.

I have fours full of threes, but every overpair beats me and those are the hands most likely to continue. With no bet facing me, checking controls the pot and lets weaker hands bluff or catch up.

On a paired trips board, K-high has decent equity and our range advantage favors a small c-bet that folds out better unpaired hands and denies equity.

I have a full house on a triple board and seat_1's small flop bet is a clear value target, so I raise rather than flat.

K6 high on a 444 board is near the bottom of my range against a check-raise from a range heavy in pocket pairs, Ax and trips. I'd have poor realization against further barrels, so folding beats calling at 25% pot odds.

65o is too weak to call or raise from the button against two live blinds; folding avoids a dominated spot.

Blind vs blind with an Ace blocker, raising to 3bb puts immediate pressure on the big blind.

Getting 3:1 in position against a wide small-blind steal, T2o has enough equity to defend with a call.

The board heavily connects with the big blind's calling range, so checking our Ace-high gutshot out of position is the safest and most standard line.

With an open-ended straight draw plus a backdoor flush draw, I'm in position after a check. A two-thirds pot semi-bluff can take the pot now and still has equity when called.

Holding only Ace-high with a backdoor flush draw on a very wet, coordinated flop that heavily favors the defender's range, calling a 2/3 pot bet out of position is unprofitable.

93o is too weak to open from the button even in 3-handed play.

In a blind-vs-blind spot, K3o is a standard opening hand from the small blind, so I'm raising to 3bb rather than limping or folding.

34 offsuit is too weak to continue against a preflop raise, so folding is the highest-EV option.
