Hold'em table

Opening from the button with a pocket pair is standard in 3-handed play. Raising to 2.5bb applies pressure and builds the pot in position.

8-4 offsuit is a weak hand out of position in the small blind, facing a button raise to 250 with the big blind still to act behind. Folding is the best option.

9-6 offsuit is a weak hand out of position against two players, so I'm folding to the big blind instead of paying 100 to see a flop.

Jd8d suited is a reasonable hand heads-up; raising to build the pot and take initiative against the lone remaining opponent.

32s is too weak to profitably defend against a 3bb open, even with position blind vs blind.

J8 offsuit from the button facing a raise-to-call situation isn't strong enough to invest in; folding preserves chips for better spots.

Holding an ace blind-versus-blind after the button folded, raising to 3bb applies pressure and takes the betting initiative.

4d9d is a marginal suited hand, but getting 2:1 on a call in the big blind against a small blind raise to 3bb is good enough to defend, and a 3-bet bluff isn't warranted.

I flopped top pair with a weak kicker on a very coordinated board; checking keeps the pot manageable out of position.

The board is K-T-A with two hearts, and I hold 4d9d, which has nothing except a backdoor diamond draw. Seat 1 checked as the preflop raiser, so a small stab of half pot can win the pot now. The board hits the raiser's range hard, so I'm keeping the bet small to limit the cost if I get called.

I hold top pair on a wet board and have good pot odds (calling 300 into 900) to continue against the big blind's bet.

The board is heavily coordinated with a four-to-a-straight texture where any Jack makes Broadway. Checking our top pair weak kicker to control the pot is the standard line.

The board is Kh Ts Ah Qd and I hold 4d9d, which is only a weak flush-draw-less nothing (a 9 gives no straight since J is needed). The board already has a Broadway straight draw, so checking back keeps the pot small and avoids bluffing into a possibly strong range.

The board has four to a broadway straight and a paired ten; any worse hand folds and better hands call or raise, making a check optimal.

The board is K-T-A-Q-T and I hold 4d9d, so I have nothing and no showdown value. Seat 1 checked three streets and capped their range, so a half-pot bluff should fold out hands like a weak Ace or a pair. Any Jack makes a straight, so I am bluffing the many hands that don't have one.

I hold top two pair (Aces and Tens) with a King kicker on a board where many straight draws may have checked the turn. Getting 3:1 pot odds, calling is profitable against bluffs, missed flush draws, and chopped Aces.

Nine-six offsuit is too weak to open from the button even in a 3-handed game.

A6o is a decent heads-up hand with an ace blocker. The button folded, so I'm in the small blind against the big blind and raising for value and initiative is better than completing.

J4 offsuit is weak against a raise with only one opponent left; not worth defending out of position.

A6 suited on the button in a 3-handed game is a strong enough hand to raise for value and to take the initiative against two blinds who have not shown any strength.

53 offsuit is far too weak to defend out of position against a 3x open.

4-5 offsuit from the button facing a raise-limp situation isn't strong enough to invest chips; fold and wait for a better spot.

94o is too weak to complete or raise from the small blind out of position.
