Holdem table

Pocket aces on the button: open-raise to 2.5bb to build the pot while keeping weaker hands in to call.

2h6c offsuit is too weak to defend from the small blind against a button open with the big blind still behind.

Pocket queens are well ahead of a typical button opening range. A substantial three-bet builds the pot and charges weaker hands to continue while out of position.

Pocket aces facing a 3-bet from the big blind, so I 4-bet for value to around 2.4x, which builds the pot while keeping their continuing range wide.

QQ is strong enough to shove against a button four-bet at 100bb, with value against weaker hands and fold equity against bluffs.

Pocket aces are the best preflop hand, so calling the all-in is clearly profitable against any range.

Open-raise the button with suited-ish connected 9-7 offsuit is not ideal, but positional pressure against the blinds makes a small raise preferable to limping.

8h2s is a weak offsuit hand with poor playability, especially out of position against a button raise and with the big blind still to act.

Getting about 2.7:1 against a wide 3-handed button open, and T5o has enough equity to defend from the big blind. A 3-bet isn't justified, so I'll call.

A gutshot to the 7 plus a backdoor flush draw is a reasonable hand to check from the big blind against the button's range. I can then decide on a check-raise or a call based on the button's bet size.

Betting top pair with an open-ended straight draw on this coordinated board for value and protection. A substantial sizing charges flush draws and weaker made hands.

Against a small c-bet, I'm getting about 3.4:1. A gutshot to the 7, an overcard ten and a backdoor diamond draw are enough to continue. Calling keeps the pot manageable, and my straight would be somewhat disguised if it comes in.

I have an open-ended straight draw (a 7 makes the straight, about 8 outs), and the paired turn doesn't help my range much when leading. I'll check and decide based on the button's action.

I have top two pair on a coordinated board and should value bet against one-pair eights, draws, and worse nines. A moderate sizing charges the diamond and straight draws while retaining calls from weaker made hands.

I only have a gutshot to the straight (4 outs, about 9%) against a double barrel on a paired board. Calling 800 into a pot of 2150 needs about 27% equity, so folding is best.

K9 offsuit is strong enough to open from the button three-handed. A 2.5-big-blind raise pressures the blinds while preserving position postflop.

52 offsuit is far too weak to continue from the small blind against a button open, with the big blind still left to act behind me.

Q7 offsuit is too weak to defend out of position against a button raise, especially with the small blind already folded.

K8o is a standard open from the button in 3-handed play, first to act; raising to 2.5bb puts pressure on both blinds.

AQ offsuit is a strong three-handed hand, and a sizable small-blind 3-bet can isolate the button opener and deny the big blind attractive odds.

Q2 offsuit is too weak to defend the big blind against a substantial three-bet, especially with the original raiser still to act.

K8o is too weak to continue against a small-blind 3-bet to 9bb, even out of position for them; calling 6.5bb to win 12.5bb requires about 34% equity, and K8o plays poorly against a 3-betting range.

K9 suited is a reasonable button open in three-handed play. A 2.5bb raise applies pressure while retaining maneuverability.

J8 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

42o is at the very bottom of the big blind's defending range against a 2.5x button open. It would realize its equity poorly out of position, so calling 150 into 400 is not profitable enough.

KJo is a strong button opening hand three-handed. A 2.5 big blind raise builds the pot while keeping the risk measured.

J7o in the small blind facing a button open to 2.5bb, with the big blind still to act, is a clear fold. Calling out of position leaves it dominated and unlikely to realize its equity.

Q8 suited is a reasonable big-blind defense against a button min-raise-plus open, with favorable pot odds and position postflop.

I have a strong queen-high flush on a coordinated monotone board and should bet for value while charging single-diamond and straight draws.

In position, the gutshot and two overcards give me enough equity to continue against this flop bet, though the monotone board makes a raise less attractive.

I have a queen-high flush on a four-diamond board and should value-bet against kings, straights, sets, and lower diamonds. A moderate sizing can still be called while limiting exposure to the rare ace-high flush.

Top pair with a diamond draw and a gutshot has enough equity to call. Raising risks building a large pot against a made flush or stronger hand.

I have a queen-high flush and should value bet against kings, two pair, sets, and smaller diamond holdings. A moderate river sizing can still be called by worse while limiting exposure to a higher flush.

Top pair with a jack kicker is a bluff-catcher against three substantial bets on a monotone flop. The river bet offers insufficient odds against the likely value-heavy range.
