Hold'em table

K9o on the button in a 3-handed game is a reasonable hand to raise with, applying pressure on the blinds and taking initiative with position.

I have 8c Td, a decent suited broadway hand. The pot is 400 and I only need to call 150 more. With only one opponent remaining and no aggression from them, calling is a reasonable play to see a flop.

I have an open-ended straight draw with 8c-Td on a 5c-Kh-6d board, but I'm in position as the big blind and the button has shown strength by raising preflop. Checking allows me to control the pot size, keep my opponent's range wide, and realize my equity cheaply while preserving stack depth for future hands.

I have top pair with a decent kicker on a draw-heavy flop, and the big blind checked after calling preflop. Betting for value and protection is best, sizing around two-thirds pot.

Calling keeps the pot live with a backdoor straight draw and a ten-high flush possibility, while avoiding a difficult bluff into a likely strong hand.

Board is dynamic with a straight draw and flush possibility; my 8c-Td gives a gutshot to the 7 and a backdoor flush draw, but I have no made hand. Checking keeps the pot controlled and lets me see the river cheaply while preserving the option to bluff or call later.

I have top pair with a decent kicker and position. Betting for value and to charge straight draws on a coordinated board.

I have top pair with a strong kicker on a dry board, and the opponent's turn raise is likely a bluff or a thin value bet. Calling keeps the pot manageable and allows me to realize my equity without overcommitting.

I have an open-ended straight draw that missed on the river, so I have no made hand to value-bet. Checking is the safest play to avoid bluffing into a strong range and to see a cheap showdown.

With Ks4s on a 3-handed table, I'm out of position and facing a raise to 100 from the big blind. The hand lacks enough equity to continue, so folding preserves my stack.

I have Qd 4s on the button with a 100bb stack. Calling 100 to see a flop is reasonable; I'll keep the pot small and play postflop.

I have 8d2s in the small blind, a very weak offsuit hand out of position against two players; folding avoids investing more with poor equity and playability.

KQ is strong enough to raise for value against a limper, and I can take control of the pot preflop.

With 4s Qd on the button facing a 300 raise, the hand is too weak to call 200 and too disconnected from the board to bluff-raise effectively. Folding preserves my 100bb stack for better spots.

Suited one-gapper on the button in a 3-handed game is strong enough to raise for initiative and to pressure the blinds, while keeping the pot manageable.

2d6s is a very weak hand facing a raise out of position, so folding is the lowest-risk play.

With 6h4h and facing a 200 chip call after a 300 raise, the hand is too weak to continue; folding preserves my 100 big blind stack for better opportunities.

3-7 offsuit is too weak to invest more chips preflop, especially facing a raise and with two opponents yet to act. Folding preserves my stack for better spots.

I have 7-2 offsuit, a terrible hand, and only need to call 50 to see a flop. Folding preserves my stack against the big blind's 100 investment.

9h 5s is a weak offsuit hand with no playability preflop; folding avoids investing chips in a marginal spot.

Closing action in the small blind against the big blind after the button folded, Q5o has enough equity to call 50 into a 150 pot, and seeing a flop is preferable to raising with a weak offsuit hand out of position.

With J8o in the big blind and no raise against a single limper, checking is the cheapest way to see a flop and avoid bloating the pot with a marginal hand.

I have only queen-high with no pair or draw on a coordinated ace-high flop, and there is no reason to bloat the pot out of position. Checking keeps the pot small and lets me fold to further aggression.

With queen-high and no pair or draw on a dry-ish board, checking controls the pot and avoids risking chips with a weak hand.

I have top pair with a modest kicker and the opponent has shown weakness by checking twice, so I bet for value and to protect against draws.

Q-high with no pair or draw faces a turn bet, and the pot odds are insufficient to continue against a likely made hand or bluff.
