Hold'em table

53s is slightly too weak to open profitably from the button even 3-handed, so folding is standard.

Calling with Q-high suited in the small blind keeps the pot small and avoids a difficult 3-bet situation from the big blind. I'll see a flop cheaply and play position.

Button folded, SB limped; 64s is a fine hand to see a free flop with position disadvantage but no reason to bloat the pot. Checking keeps it cheap and lets me realize suited-connector equity.

I have a backdoor flush draw and a gutshot straight draw with Qd, but the board is dry and I'm OOP. Checking keeps the pot small and allows me to realize equity without risking chips on a marginal hand.

Bottom pair with a weak kicker on an A-Q-x two-club board; checking back in position keeps the pot small and lets me see a cheap turn or showdown rather than bloating it with a marginal hand.

The pot is small and the board is dry with no obvious draws; checking keeps the pot controlled and avoids building a big pot with a mediocre Queen-high hand.

I have bottom pair with 6s on A-6-Q-9 board; opponent has checked three times showing weakness, so a half-pot bet can take down the pot now and deny equity to overcards or draws, while a check risks giving a free river.

Calling the 100 chip turn raise keeps me in a pot with a backdoor flush draw and a queen high, while avoiding a big bluff raise that could get 3-bet. My Q-high is weak enough that folding is also reasonable, but calling preserves equity cheaply.

Board is paired with a King on the river and I hold only Queen-high with a backdoor flush draw that missed; checking avoids building a bigger pot with a marginal hand while still keeping showdown equity.

Bottom pair of sixes on an A-K-Q-9 board has thin showdown value only against busted club/straight draws; a bet folds out the hands we beat and gets called by better, so checking back is best.

J2o is a weak hand with poor equity; calling 100 more to see a flop is not profitable. Folding preserves my stack for better opportunities.

Button folded, so it's SB vs BB heads-up; 75o is a weak but playable hand with some connectivity, and a raise to 3bb takes the pot down often against a wide-ranged BB while limping gives up initiative. Folding is also reasonable, but a steal attempt has positive expectation here.

Three-betting for value with AKs in position against the small blind's open raise.

7-5 offsuit facing a 3-bet out of position is a clear fold; the hand has poor equity and playability against a 3-betting range.

AKs on the button is a premium hand; open-raise to 2.5bb to build the pot in position.

J5o is too weak to continue from the small blind against a button open.

I have 4hQc, a weak offsuit hand. Seat 3 raised to 250 and seat 1 folded, so I face a 150 to call with poor odds and no initiative.

43o is far too weak to open even from the button in a 3-handed game, making folding the standard and most profitable play.

Calling the 50 chip raise with 9cQc keeps me in the pot at a low cost while preserving stack depth, as the hand has decent playability and I want to see a flop without overcommitting.

Button folded, small blind limped; 9-6 offsuit is a weak hand so I take the free flop in position-less BB rather than bloat the pot.

I have a backdoor flush draw and a gutshot with middle pair potential, but the pot is small and I want to control the hand on a wet board. Checking keeps my options open and avoids building a big pot with a marginal hand.

I have an open-ended straight draw (6-9 on 7-8 board) with position; SB checked to me. Betting small could work but checking keeps the pot small and realizes equity cheaply with a draw that benefits from a free card; I'll bet turn if I hit or if checked to again.

Checking keeps the pot small with a weak Queen-high hand on a board that could still pair or complete a flush. I want to see the river cheaply and avoid building a big pot without strong equity.

I have an open-ended straight draw (6-9 with 7-8 on board) plus a backdoor-ish flush possibility with 6c on a two-club board; opponent has shown weakness by limping and checking twice, so a small bet can take the pot now and still has equity if called.

Calling is cheap relative to the pot and keeps the door open for a backdoor flush draw with Qc. I'll see a cheap river and decide based on the final card.

Board is paired with two 8s and a K, and my 9c-Qc is a weak showdown value; seat_3 just bet the turn and seat_1 folded, so checking to realize equity and control pot size is best.

I hold a 9-high straight (5-6-7-8-9) and the opponent checked to me on the river; betting around 65% pot extracts value from Kx, 8x, and weaker made hands while keeping the bet small enough that I can fold if raised given the flush and full house possibilities.

Calling 325 on the river with 9c Qc on a paired 8 board is a thin value/bluff-catch; I have no made hand but can call down given the pot odds and opponent's aggressive betting pattern.

I have a suited connector on the button with the blinds out of position, so I'll see a flop cheaply. Calling 100 keeps my stack intact and avoids risking too much with a speculative hand.

Button limped; completing 50 into a 250 pot with 76o from the SB is cheap with good implied odds in a multiway limped pot, while raising a weak offsuit hand out of position has little merit.

Check to see a cheap multiway flop and set-mine with pocket deuces.

I have top pair (7s) with a 6 kicker on a paired, dry board in a limped pot; a small bet for value and protection is reasonable, as opponents' ranges are weak after limping and few hands beat me.

Pocket deuces on a 4-7-4 board with a player behind is too weak to call a two-thirds pot bet.

I hold Td9d on a 4h-7s-4d flop with a tight raiser ahead. The paired board and opponent's continuation raise make my hand unlikely to be best, so folding preserves my stack.

AJo on the button in a 3-handed game is a clear value open; raising to 2.5bb takes initiative against the blinds.

Folding 74o from the small blind facing a button open.

6c9s is a weak hand that cannot stand a raise from the button. Folding avoids losing more chips with poor equity.
