Hold'em table

Nine-four offsuit is too weak to call a blind or raise from the button, so folding preserves the full stack.

Calling 50 into a 150 pot heads-up is very cheap; 97o has far more than the ~25% equity needed, and folding is too tight while raising bloats a marginal hand out of position.

Holding strong suited connectors in position against a small blind limp, raising builds the pot and exerts pressure.

7h9d is far too weak to call a 3.5x raise out of position against the big blind; the required equity (~36%) exceeds what this hand realizes versus a raising range, so folding preserves chips for better spots.

J6o is too weak to play out of position blind versus blind, making folding the standard play.

Opening on the button with J9o in 3-handed play to apply pressure and leverage position.

4-2 offsuit is too weak to continue against a button raise to 2.5bb; folding saves chips.

Calling 150 into a 400 pot gives ~2.7:1 odds, and A3o has enough equity against a wide button opening range in 3-handed play. I keep the pot small with a weak kicker rather than 3-betting.

I only have ace-high with no pair and no flush draw on a monotone flop, so checking costs nothing and keeps the pot small; I'll fold to meaningful pressure since my only real hope is a non-diamond jack for the nuts.

I flopped a straight, but the monotone diamond board makes the hand vulnerable without any diamond redraw. Checking behind controls the pot size in position.

I only have ace-high with no draws on a monotone flop, so betting would just bloat the pot against a preflop raiser who checked back. Checking keeps the pot small and lets me fold cheaply if he fires the turn.

We made a straight on a monotone board. Seat 2 has checked twice, so betting offers value against pairs and charges single diamond draws.

I hold ace-high with no diamond draw on a monotone board, so calling 350 into 900 against a preflop raiser's turn bet has almost no equity or showdown value. Folding preserves chips for better spots.

K7s is a standard button open in three-handed play; a 2.5bb raise builds the pot with position and suited connectivity.

5-6 offsuit is far too weak to call 200 more out of position with the big blind still to act behind me; folding is the cheapest and best line.

J4o is an unplayable hand out of position against a button raise, making this an easy fold.

Nine-two offsuit is one of the weakest hands even from the button in 3-handed play; calling or raising risks chips with poor equity against two random hands.

Q7 offsuit plays poorly out of position postflop against the big blind, making a fold the cleanest play.

A7o on the button in 3-handed play is well within the standard opening range; raising to 200 applies pressure on the blinds.

92 suited is too weak to continue out of position against a button open; folding saves chips for better spots.

Only 100 more to call into a 350 pot with connected 65o; cheap BB defense against a button min-raise with decent implied odds if I flop straight or pair draws.

My 6-5 flopped an open-ended straight draw (any 3 or 8) on K-7-4, but no made hand yet. Checking keeps the pot small and may win a free card against the preflop raiser's likely K-high range; I can semi-bluff later if needed.

I have middle pair with top kicker on a dry K-high board, which plays well as a check behind for pot control and showdown value.

My 6-high has essentially zero showdown value, and the preflop raiser checked back the flop, so a two-thirds-pot stab has good fold equity; I can easily fold if raised.

I hold third pair with top kicker in position, getting good odds to call a single turn probe after checking through the flop.

My best hand is only king-high (K-T-7-6-5), which loses to virtually every hand that called the turn bet. Checking is free; bluffing into a turn caller on a paired river has almost no fold equity, and any bet from me just risks more chips with the worst hand.

I have two pair (Tens and Sevens with an Ace kicker), which has solid showdown value against missed draws and bluffs, but very few worse hands would call a river bet.
