Hold'em table

Pocket jacks are a premium hand on the button, so I open-raise to 3bb to build the pot and take the initiative.

84o in the small blind facing a 3x button open with the big blind still to act is a clear fold. It plays poorly out of position.

6h 8d is a weak hand with no playability. The raiser has position and initiative, and calling 200 with this hand is a -EV play.

32 offsuit is too weak to open from the button in a 3-handed game with 100bb stacks; folding is standard.

6c 8h is a weak offsuit hand with no pair and poor post-flop playability. Facing a 50 chip call from the small blind with the button already folded, folding minimizes losses with a hand that is unlikely to win at showdown.

With As7h on the button, I'm folding to the 100bb big blind raise. The hand is too weak to continue and I want to preserve my stack for better spots.

76o is too weak to continue out of position heads-up; the extra 50 does not justify a dominated, poorly realizing hand.

A3o is playable as a button open in three-handed poker; a small raise steals the blinds and keeps the pot manageable with a weak kicker.

74s from the small blind facing a 2.5x button open, with the big blind still left to act, is a weak out-of-position spot. Folding is better than flatting or 3-bet bluffing with such a low-equity hand.

I have a pocket pair of nines, which is a decent hand but not strong enough to raise preflop. Calling keeps me in the hand at a reasonable cost while avoiding overcommitting with a marginal holding.

I have a set of nines on a 3-6-9 flop with no overcards threatening me, and the opponent's preflop raise was modest. Checking allows me to control the pot and potentially induce a bluff or see a free card.

Bottom pair with an ace kicker has some showdown value on a dry board, but it is too weak to bet for value and too vulnerable to a check-raise. Checking realizes equity cheaply after the opponent checks.

I have a set of nines on a paired board with a possible flush draw, but I want to control the pot and keep the opponent's bluffs in. Checking allows me to potentially induce a bluff or take a free card while minimizing risk.

I have sixes and threes with an ace kicker on a paired board, ahead of ace-high and many draws. A small turn bet gets value and protection after the opponent checked twice.

I have a set of nines with a pair of sixes on board; calling is low-cost relative to pot and preserves stack against a possible bluff or weaker hand.

The board is paired with a 6, and my pocket nines are vulnerable to a better full house or quads. Since the opponent checked back the flop and called a turn raise, I want to control the pot and avoid building a big bet with a marginal hand.

I have only a weak pair of threes on a paired board, and a river bet is unlikely to be called by worse. Checking realizes showdown value for free.

32o is one of the weakest hands. Even on the button in a 3-handed game it is a clear fold against two players left to act.

Calling with 2sTc in the small blind is reasonable since the big blind is the only opponent and the pot odds are favorable. I'll see a flop cheaply and play positionally.

Q9o is too weak to raise out of position against a completed small blind, and checking is free so folding is pointless.

I have a backdoor straight draw with 2s-Tc on a Jd-3c-Kc board, but no pair yet. Checking preserves my stack and lets me see the turn without committing more chips.

Queen-high with no pair or draw has little fold equity worth paying for; checking keeps the pot small against the SB who already checked.

The board is high and coordinated with J-K-Q, and my hand (2s Tc) is weak with backdoor flush potential only. Checking keeps the pot small and avoids building a big pot with a marginal hand on the turn.

Second pair with a weak kicker on a king-high board; opponent has shown no aggression, so checking controls the pot and avoids value-owning myself.

Board is paired and scary with Kc Ks and Qd, and my 2s Tc is weak; checking keeps the pot small and avoids building a bluff catcher into a likely better hand.

I have kings and queens, which has showdown value, but any king beats me and a queen chops. With the river checked to me in a tiny pot, checking realizes equity without risking a raise from trips.

I have a suited-ish connector (8h9c) in position on the button, so calling the 100bb big blind is reasonable to see a flop. Folding would be too weak, and raising would isolate me out of position postflop.

Pocket jacks are well ahead of a button limp, so I raise to build the pot and deny cheap flops before the big blind acts.

Q7s is suited and gets about 2.9:1 against a likely wide isolation raise from the small blind. We will also have position on the small blind postflop, so calling is a reasonable defend.

8h9c is a speculative hand that plays well postflop; calling keeps the pot manageable and preserves stack for implied odds. Folding would waste equity, and raising is too thin preflop with only two opponents.

Dry ace-high flop and I was the preflop raiser, so a small c-bet gets value from worse pairs and denies equity while keeping the pot manageable out of position with jacks.

Q-high with only a backdoor flush draw on an ace-high board facing a bet from the preflop raiser, with another player still to act; there isn't enough equity to continue.

I have a gutshot straight draw with 8h9c on a 4h-Ad-2s board, giving me backdoor flush potential and a backdoor straight. Calling 450 into a 1800 pot is reasonable to keep the opponent's range honest and see a turn without overcommitting.

Pocket jacks have showdown value but the ace and paired board make a turn bet thin; checking controls the pot against the caller.

I have an open-ended straight draw with 8h 9c on a 4h Ad 2s 4c board, but the opponent bet 450 on the flop and I called. Checking back the turn is a standard play to control pot size, keep the opponent's range wide, and potentially induce a bluff or take a free card. My stack is 9100, so I have plenty of room if I need to act later.

Pocket jacks have showdown value but lose to many Ax and trip-four hands that called the flop. With no bet facing me, checking realizes that value without bloating the pot.

Board is paired with a 4 and I hold 8h9c, so I have a weak pair at best. Checking lets me see a showdown without investing more chips into a pot where seat_1 likely has a stronger hand.
