Hold'em table

K3o is a standard button open three-handed, since only the blinds are left to act. A 2.5bb raise lets me take down the blinds often and plays fine postflop in position.

J2 suited is too weak to defend from the small blind against a button raise with the big blind still behind.

AQs is strong enough to three-bet for value and to take initiative against a button open. This sizing pressures the opponent while keeping room to play postflop.

K3o is too weak to continue against a BB 3-bet to 8bb, even with position; calling 550 into 1100 leaves me with a dominated, low-equity hand.

6-3 offsuit is a very weak button holding and not worth entering against two blinds at this stack depth.

AJs is strong enough to raise for value and to put pressure on the big blind, who is the only remaining opponent. I take the initiative with a standard raise to 300.

Blind vs blind, A4o getting 3:1 odds is a clear defend; calling keeps SB's wide range in and gives me position postflop, while 3-betting is also viable but calling is fine.

I raised preflop and this flop is unlikely to have hit the caller hard; a continuation bet can take the pot now or set up turn pressure with my overcards and backdoor flush draw.

Against a half-pot c-bet we need about 25% equity, and ace-high with backdoor nut-flush and wheel draws is a reasonable float that helps meet minimum defense frequency.

Nut flush draw plus wheel gutshot and an ace overcard make a strong semi-bluff. The opponent's check was a timeout fallback, which suggests weakness or inattention, and if they time out again facing a bet, they fold.

A6s is a strong hand in a blind-vs-blind spot, so raising to 3x for value and initiative is standard.

JTs suited is a strong heads-up big-blind defense versus a small-blind open. A 3-bet to 9bb applies pressure while retaining postflop playability.

A6s has solid equity and playability against a wide blind-vs-blind 3-bet range. At 2.8:1 pot odds, calling is better than folding, and flatting keeps dominated hands in the pot.

Out of position against a 3-bettor with A-high, a gutshot to the wheel and a backdoor flush draw, checking lets the preflop raiser c-bet so I can check-raise or call. Leading into their range isn't necessary.

I bet one-third pot after the check to apply pressure with two overcards and some backdoor club potential in a heads-up 3-bet pot.

Getting 4:1 on a small c-bet with ace overcard, backdoor flush and straight draws, and some showdown value. Calling is clearly better than folding, and raising isn't necessary.

With the nut flush draw plus a gutshot (about 12 outs), I'm leading as a semi-bluff to take the initiative. It wins through folds or through my equity, and it sets up a shove on good rivers.

We have only a gutshot to a nine and no meaningful made hand against a substantial turn barrel. The direct pot odds are far too poor to continue.

AJo on the button in 3-handed play is a strong open; a standard 2.5bb raise.

J5 offsuit is too weak to defend from the small blind against a button open with the big blind still behind.

83o is too weak to continue out of position against a raise, so I fold to preserve chips.

5-2 offsuit is too weak to open from the button in this stack-reset format.

Blind vs blind with 9-4 offsuit, getting 3:1 to complete; a cheap limp is acceptable, though folding is close.

QJ offsuit is a strong heads-up big blind hand against a limp. I raise for value and to deny equity.

94o is far too weak to call 400 more out of position against a big blind raise after my limp; folding is clearly best.
