Hold'em table

Button open with an ace-high hand in a 3-handed pot; raising to 250 to build the pot and take initiative.

K3 offsuit is too weak to continue out of position against a button open; the king is dominated often and the hand plays poorly postflop.

Button folded, so this is heads-up versus the big blind with KQo, a clear value open. Raising to 300 builds the pot and denies a cheap flop.

Weak offsuit hand (2h Ts) facing a 3x raise with only one opponent left; not worth continuing.

73o is too weak to open first-in even on the button in a three-handed game; folding avoids a dominated, low-playability hand.

Heads-up now after button folded; J9 offsuit is playable, so raising to build pot and take initiative against BB.

Pocket kings are the second-best starting hand; 3-betting for value against the small blind's open builds the pot and applies maximum pressure.

J9 offsuit facing a 3bet to 750 (7.5bb) with a caller behind is too weak to continue; folding preserves chips for better spots.

Weak offsuit low cards (3-8) with no connectivity; not worth calling from the button in a 3-handed pot facing a raise-sized call.

J7o in the small blind is too weak to raise but cheap enough to call 50 and see a flop heads-up.

A7o is playable but not strong enough to raise out of position against a wide small-blind complete. Checking keeps the pot small and realizes the hand's showdown value.

I only have jack-high with a weak gutshot on 9-2-8, so with no fold equity established I'll check and realize equity cheaply rather than bluff into the big blind.

Ace-high has no pair or draw on a dry 9-8-2 board, and the small blind already checked. Checking keeps the pot small and preserves showdown value.

I hold only jack-high with no draw on a paired board, so betting has little fold equity and calling a bet would be unprofitable. Checking keeps the pot small and lets me fold cheaply to aggression.

Ace-high has some showdown value on a paired board after the small blind checked twice, and a bet risks being called or raised by any pair. Checking keeps the pot small and realizes the hand cheaply.

My J-high is almost certainly beaten if anyone bets, so I take the free showdown rather than bluff into a paired board where seat_3 has shown no aggression.

Ace-high has some showdown value on a paired board after seat_2 checked every street. Betting mostly folds out worse hands and gets called by pairs, so checking is best.

KQs is a strong button hand; raising for value and position with a standard 3x open.

92o is too weak to continue out of position against a button raise, with the big blind still to act. Folding avoids putting more chips in with a dominated offsuit hand.

KQs is strong enough to 3-bet for value/isolation against a single raiser, especially with the third player already out.

KQs has decent equity against a 3-bet range and I'll have position on the 3-bettor postflop, so calling 600 to see a flop is better than folding or 4-betting a dominated hand.

I flopped top pair of queens with top kicker plus a backdoor nut straight draw on a wet board, so I want to bet for value and protection against draws.

K6o is playable as a button open in three-handed poker with position; a small raise applies pressure to the blinds better than limping.

T2 offsuit is a weak hand facing a raise; folding is correct even from the small blind.
