Hold'em table

A7 suited-ish (offsuit ace) on the button is a solid raising hand heads-up-ish; raise to 250 to build pot and take initiative.

Pocket sevens are a profitable call against a 2.5x button raise in 3-max; I have set-mining odds and a decent hand that plays well postflop. Folding is too tight, and 3-betting with 77 out of position adds unnecessary risk.

A4o is too weak to continue multiway out of position against a button raise and a small-blind call, where better aces dominate me.

Pocket sevens on a K98 board are rarely ahead of the preflop raiser's continuing range (K-x, overpairs, 99/88), and donking out of position has little fold equity. Checking keeps the pot small and lets me fold to serious aggression or re-evaluate a small bet.

As preflop raiser I'll continue with a c-bet on this dry-ish board; my ace-high has some equity and decent fold equity against a check.

My 77 is only third pair on the K-9-8 flop with no meaningful draw, and the preflop raiser betting half pot represents plenty of kings, overpairs, 99/88. I need ~27% equity to call and have far less, so folding is clearly best.

On the button 3-handed, a min-raise to 200 is a cheap steal attempt with position; Q7o is marginal but the risk is small and folding the button this wide is too tight.

Jack-ten suited plays well against a button min-raise, and the price to continue is only 1.5bb. Calling keeps the pot small out of position rather than bloating it with a three-bet.

KQ offsuit is a strong hand heads-up-ish situation; raise to build pot and isolate against two limpers/callers.

Q7 offsuit is far too weak to continue facing a 3-bet from the big blind after my open; folding loses only 200 chips versus risking 500 more with dominated equity.

JTs is too weak to continue out of position against a BB 3-bet after the opener folds; calling 500 into 1100 does not justify the reverse implied odds.

J5 offsuit is too weak to open from the button; folding avoids a dominated, poorly playable hand out of position postflop.

Heads-up with button folded, cheap price to see a flop with reasonable pot odds.

I'm in the big blind with 2s5s and the small blind just limped, so checking costs nothing and lets me see a free flop with a suited hand that can make a low flush or two pair.

Board is AA Q, my hand has little equity; checking to control pot size since I have no pair or draw.

I hold 2s5s with no pair, draw, or showdown value on Ah-Ad-Qh; seat_1 checked the flop, so checking keeps the pot free and I can fold to any bet.

I hold two pair (aces and tens) plus a strong four-flush draw on a scary board; betting builds the pot for value while opponent has shown weakness by checking twice.

My hand is just the board's two aces with a 2-5 kicker, so any ace, pocket pair, or better two pair from seat_1 wins. His flop check-turn bet pattern strongly suggests an ace, and calling 200 into a marginal spot has no value.

K3 offsuit is a weak hand not worth entering the pot from the button facing a raise cost with two players behind acting after blinds; better to preserve chips.

J8o on the button 3-handed is a standard open; raising to 2.5bb applies pressure on the blinds and builds a pot with position.

AJo is ahead of a wide button open in three-handed play, and three-betting from the small blind takes the initiative rather than playing out of position. An 8bb raise is a standard size with fold equity and value.

J8 offsuit facing a raise and a big 3-bet to 800 is far too weak to continue; folding avoids a costly spot out of position.

J8 offsuit is far too weak to call a 3-bet of 800 after my own raise; folding loses only the 250 already invested and preserves chips for better spots.

86 offsuit is too weak to open from the button even three-handed; folding avoids putting chips in with a dominated, unsuited hand.

86o offsuit is weak; button folded but facing BB with a weak hand not worth defending here.
