Hold'em table

73o is far too weak to open even from the button in a 3-handed game. Folding is standard.

KQs in the small blind heads-up against the big blind after the button folded is a strong hand, so raising to 3bb for value and initiative is better than just calling.

JTo is strong enough to defend against a small-blind 3x raise, and calling keeps weaker hands in while giving me position after the flop.

Heads-up on J-5-5 with KQ of clubs, I have overcards and a backdoor flush draw, and I raised preflop. A continuation bet of about two-thirds pot takes the initiative and can fold out hands like A-high or small pairs.

Top pair with a ten kicker is strong enough to continue, but on this dry paired board a raise would often fold out worse hands and isolate stronger ones.

I have K-Q with a backdoor club draw and two overcards on a paired J-5-5-3 board, and I'm first to act on the turn. A half-pot bet takes the initiative as a semi-bluff. Seat 3 only called twice, so their range is capped and they may fold weaker pairs or draws.

Top pair with a ten kicker is strong enough to call this turn bet, but raising would risk isolating against stronger hands.

I have king-high with a queen kicker on a Js 5c 5d 3h 5h board, so I only win against a pure bluff. Seat 3 called the flop and turn and likely has a jack or a pocket pair that beats me. Betting would mostly get called by better hands and fold out only worse ones, so I check for a free showdown.

I have a full house, and a small river bet can get value from lower pocket pairs or a three. It also limits my loss when the opponent has a higher full house or quads.

I have only king-high on a paired board of 5-5-5-J-3. Seat 3 called the flop and turn and now bets 600 into 2800, which looks like a value bet. Calling would cost 600 to win 3400, so it needs about 15% equity, but my king-high mostly beats only bluffs, and a big-blind caller would rarely bluff here. Folding is safest.

7d Jd is a weak offsuit-ish hand from the button in a 3-handed pot; the call is cheap but it plays poorly against two players yet to act, so folding is the conservative choice.

With the button folded, A5 offsuit is strong enough to raise heads-up against the big blind and gain fold equity.

54 offsuit is too weak to defend against a 3bb small blind open.

Pocket eights are strong enough to open on the button, and a 2.5-big-blind raise builds the pot while preserving position.

T6o is too weak to continue out of position facing a button open raise.

3-2 offsuit is the worst starting hand, and calling 150 to win a 400 pot out of position against a button raiser isn't profitable, so I fold.

43s is on the bottom fringe of playable hands even on the button in 3-max; folding avoids low-equity postflop spots out of position against 3-bets.

Ace-x suited-ish wheel hand, A2 offsuit is decent heads-up against the big blind after the button folded; raising in the small blind takes the initiative with a playable ace.

Q7 offsuit is strong enough to defend the big blind against a small-blind raise, especially with position after the flop.

Top pair with an ace on A-K-3 rainbow is strong in a heads-up pot. I'm first to act, so I bet about two-thirds of the pot for value and to charge king-x and draws. The weak kicker is a minor concern.

Q7 offsuit has no pair or meaningful draw on this A-K-3 flop. Calling 400 against a preflop raiser is unlikely to be profitable.

On the button in a 3-handed game, 7c6s is a playable suited-ish connector-type hand. Calling 100 to win a 250 pot gives a good price and position, so I'll see a flop rather than fold or bloat the pot.

Completing costs 50 into a 250-chip pot. Despite the weak offsuit hand and poor position, the price is good enough to see a flop.

I have a weak offsuit holding in the big blind facing two limpers; checking to see a free flop is the standard play.

My hand has little equity on this board, and betting into two opponents is unlikely to be profitable. I’ll check and avoid investing more without improvement.

I have third pair with a weak kicker in a 3-way pot on a coordinated board, so checking to control the pot is the standard line.

I have an open-ended straight draw (7-6 on 9-K-T) and act last after two checks. A small bet can win the pot right now, and if called I still have plenty of outs.

I have no pair or meaningful draw on this flop, and another player remains to act. Calling the bet is unlikely to be profitable.

Bottom pair with a five kicker on a wet, connected board has poor playability and equity out of position facing a flop bet.

T-2 offsuit is too weak to open from the button against two unknown opponents.

Q4o is too weak to complete or raise from the small blind out of position.
