Hold'em table

92o is too weak to open from the button in 3-handed play against two blinds at 100bb, so folding is the low-variance default.

Button raise with a suited hand (Q9s) to build pot and leverage position against both blinds.

4-6 offsuit is too weak to defend from the small blind against an early 2.5bb open with the big blind still behind.

Getting about 3.7:1 against a wide 3-handed button open, so 94o is a marginal but acceptable big-blind defend. Calling keeps the pot small while I realize equity.

I have a weak gutshot (needs a J) with no pair out of position against the preflop raiser on a board that favors them. Checking keeps the pot small and lets me realize my equity cheaply.

Top pair with a decent kicker on a dry-ish board; betting for value and to deny equity to overcards/draws.

A gutshot to the jack, plus a 9 overcard to the 5, getting 3.8:1 against a small c-bet from the button's wide range makes this a reasonable defensive call. Facing that sizing, folding would be too tight.

I picked up an open-ended straight draw (K or 8) but have no pair, so I'm checking for a possible free card. I can decide whether to call or check-raise as a semi-bluff if the button bets.

I have top pair of queens plus an open-ended straight draw, a strong hand that benefits from betting for value and protection against draws.

I have an open-ended straight draw (any 8 or K, 8 outs, about 18% equity). The price is 700 to win 2550, about 27%. Deep stacks give enough implied odds to justify calling.

I have a king-high straight, which loses only to an ace. Leading for value should get calls from sets, two pair and Kx, which might check back on this four-to-a-straight board.

I hit a King-high straight (9-T-J-Q-K) which beats most of villain's likely value range from their check-call line; I raise for value while leaving some room in case they have the nut straight with an Ace.

I have a king-high straight, which loses only to an ace and chops with a nine. At about 31% pot odds, calling is clearly profitable, while shoving would only get called by hands that beat or tie me.

7-4 offsuit is a weak button hand and not worth entering against two blinds at this stack depth.

Blind vs blind with A7o is well ahead of the big blind's range, so a 3bb raise from the small blind is a standard value raise. It also takes the initiative into the flop.

98s on the button in 3-handed play is a clear opening hand; a 2.5bb raise applies pressure to the blinds while keeping the pot manageable.

Qs2c is a weak, dominated holding versus a button open, and defending out of position is not worthwhile at this sizing.

7h4c offsuit is a weak button hand facing a raise-sized pot entry; folding preserves chips given poor equity and no position advantage post-flop against two live players.

Small pocket pair has sufficient equity heads-up against the big blind, and completing preserves pot control.

KQs is well ahead of a small-blind limping range, so raising for value and initiative from the big blind beats checking. A raise to 4bb is a standard size against a limp.

Calling with pocket threes is profitable at this depth against a big blind isolation, as we can realize set value heads-up.

I have flopped quads and should check to the preflop raiser, preserving their opportunity to continuation-bet or improve.

As the preflop raiser on a dry, paired low board, a small c-bet with KQ high (backdoor clubs) folds out many of the limper's weak hands and keeps our range advantage.

With flopped quads on a dry paired board, calling preserves the opponent's bluffs and weaker made hands. Raising is likely to fold out most of their range.

I have flopped quads on a board where a queen, overpair, or 4 can plausibly continue. A moderate turn value bet builds the pot while preserving calls from those holdings.

Top pair with a king kicker on a paired board is a strong bluff-catcher against a turn donk-lead, and calling 850 into a 3040 pot needs only about 28% equity. Raising would mostly fold out worse hands and get called by better ones.

I have quads and should lead for value rather than risk a check-back. A substantial but non-all-in sizing can be paid by queens, aces, and pocket pairs that improved or feel committed.

Second pair with a king kicker is getting about 28% pot odds against a range that still includes missed spade and straight draws, plus weaker queens. Folding is too tight and raising only gets called by better hands, so calling is the best option.

7-5 offsuit is a weak button holding and not worth entering against both blinds at this stack depth.

Blind vs blind, Q5o is a reasonable open-raise from the SB against a single BB. Raising to 3bb takes the initiative and gives fold equity.

T4o offsuit is weak against a raise; folding is correct here.
