Hold'em table

Weak offsuit hand (2-9) with no connectivity; not worth entering as button in a 3-handed pot facing a raise to call.

Complete the small blind with a playable heads-up hand and realize equity cheaply against the big blind.

T6s plays well in position against a limping small blind, so I raise for value and fold equity. Checking is also fine, but a 4x iso-raise exploits the weak limp.

T5 offsuit is too weak to continue versus a large big-blind raise when out of position.

Q9 suited is a solid button opening hand three-handed, with position and useful playability. I open to 2.5bb to apply pressure while retaining maneuverability.

64o from the small blind facing a button open, with the big blind still to act, is a clear fold; it plays poorly out of position.

4h9c offsuit is weak; facing a raise to 250, not worth calling out of position.

74o is too weak to open even from the button in 3-handed play against two blinds, so folding is the low-variance, +EV-neutral choice.

A7 offsuit is a solid hand heads-up against just the big blind, so I raise to build the pot and take initiative.

A5 offsuit is too weak to defend out of position against a small-blind raise in heads-up play without deeper positional advantage.

Suited connector on the button with no action yet; raising to build the pot and use positional advantage.

A6 suited is a strong candidate to 3-bet from the small blind against a button open, using its ace blocker and suited playability. The larger out-of-position sizing pressures the opener and discourages the big blind from entering.

Q2o facing a raise and a 3-bet from the small blind is a clear fold; calling 900 out of position with the original raiser still behind is unprofitable.

7-4 offsuit is a weak button opening hand in this short-handed setup and does not justify investing chips.

In a blind-vs-blind spot, 33 is well ahead of the big blind's range, so a 3x raise is a standard value play that also takes initiative. Limping would play out of position with a weaker range.

KQs is strong heads-up against a single SB raise; 3-betting builds the pot and can isolate or win preflop.

With 100bb effective, calling 600 to set-mine with 33 gives good implied odds of about 15:1 against a 3-bet range. A 4-bet would turn a small pair into a bluff and fold out worse hands.

We flopped quad threes, the nuts, out of position against the 3-bettor. Checking lets the preflop aggressor c-bet and keeps his overpairs and bluffs in.

Dry paired board favors the preflop aggressor; a c-bet with overcards and a backdoor flush draw applies pressure on a likely weak check from villain.

I hold quad threes, so calling keeps the opponent's overpairs and bluffs in and invites more barrels on later streets. Raising would risk folding out their weaker holdings.

I hold quad threes, the effective nuts. Checking to an aggressive 3-bettor invites another barrel that I can check-raise, while giving them a free card costs almost nothing.

I have two pair (queens and threes) with a king kicker, a strong hand on this board; betting for value against a passive opponent who has been checking and calling.

Quad threes are the absolute nuts here. Calling keeps this aggressive opponent's bluffs and overpairs in the pot, and invites a big river bet, which I can then stack off against.

Quad threes are the effective nuts on this board, so I'm getting the remaining stack in. Opponent's three-bet range has plenty of aces and big pairs that can call.

Three-handed on the button, a wide stealing range makes 75o a marginal but playable open, so I'm raising small to 2.5bb to pressure the blinds.

Q5 offsuit is weak out of position facing a raise; folding preserves chips for better spots.

T4 offsuit is too weak to defend against a button raise, especially out of position heads-up.
