Hold'em table

On the button with a weak ace, I raise to steal the blinds and take initiative in a 3-handed game. A3o is playable here and a standard open from the button.

A9 offsuit is not strong enough to defend the small blind profitably against an early 2.5bb open with the big blind still behind.

Getting 150 to win 400 in the BB against a button open, 65o has enough playability to defend by calling. It's also a reasonable 3-bet bluff candidate, but a call keeps it simple.

We flopped trips with an open-ended draw kicker (6-5 on 5-5-4), and the preflop raiser will c-bet this board often. Checking to let them bet and then check-raising or calling extracts more value while disguising our hand.

Opponent checked the flop, so I'll make a continuation bet to take down the pot with my A-high and backdoor straight potential.

I have trips with a 6 kicker plus a straight draw on a low paired board, so I'm raising for value and to charge overcards and pocket pairs while they're still likely to call.

T3 offsuit is too weak to open with at this stack depth, so folding preserves chips.

A7s is a strong hand in a small blind versus big blind spot, so I'm raising to 3bb for value and initiative.

Facing a small blind raise after the button folded, I'm getting 2:1 pot odds with a suited hand, so I'll call and see a flop rather than fold.

On 6-9-5 I have a gutshot to the straight, the nut flush backdoor and an overcard, and I'm out of position against the big blind's calling range. A small c-bet at 58% of the pot uses my preflop raise and keeps good equity if called.

QQ on the button is a premium hand, so I'm open-raising to 2.5bb for value.

4s2s is too weak to continue out of position against a raise, even with decent pot odds. Folding preserves chips for better spots.

8-4 offsuit is too weak to defend against a button raise from the big blind at this sizing.

9-5 offsuit is too weak to continue against both blinds, and calling offers poor expected value.

Completing is very cheap and T6o has sufficient heads-up equity to realize against the big blind.

Pocket threes are ahead of a small-blind limping range, so a raise to 4x takes the initiative and punishes the limp. I'll keep playing in position postflop.

T6 offsuit is too weak to continue from the small blind versus a 4bb isolation raise, especially with the button already folded.

9-6 offsuit is too weak to open profitably from the button in this short-handed structure.

63o is near the bottom of the SB-vs-BB range, and I'd be playing out of position, so completing or raising is marginal at best. Folding keeps it simple.

Pocket sixes on the button in a 3-handed game is a clear open-raise. A 2.5bb open takes the initiative and puts pressure on the blinds.

92o is too weak to continue out of position against a raise, with poor playability and reverse implied odds. Folding saves the additional chips rather than chasing a dominated hand.

J5 offsuit is marginal but gets a favorable price versus a button open and can defend the big blind heads-up.

Check to the preflop raiser with bottom pair on a coordinated board, preserving pot control while retaining showdown value and a heart blocker.

66 on Q54 two-tone has decent equity with an open-ended straight draw (a 3 or 7 completes it) plus a pair; a small c-bet denies equity and gets folds from overcards. It also plays well if check-raised.

I have a pair plus a useful heart blocker on a coordinated board, making a call versus the small continuation bet appropriate.

I lead with a pair, gutshot, and jack-high heart draw to apply pressure and retain substantial equity when called.

Middle pair with an open-ended straight draw (any 3 or 8) is getting about 28% pot odds, and there are implied odds on the river. Calling is better than folding, and raising would bloat the pot against a lead that is likely to include a Queen.

My pair of fives has some showdown value on this coordinated board, while a bluff is likely to be called by many queens, eights, sevens, and made straights.

I have an 8-high straight, which only loses to 96. That is a strong value hand against a villain who led the turn and then checked the river, so I'm betting about two-thirds of the pot to get called by queens, two pair and sets.

Bottom pair is too weak to call this sizable river bet after the opponent called the turn and bet when checked to. Their value range contains many better pairs, two-pair hands, and straights.
