Hold'em table

Button raise with Ax offsuit in 3-handed game to build pot and apply pressure.

52s is too weak to continue out of position against a button raise to 2.5bb; folding saves chips for better spots.

King-ten offsuit is too weak to defend out of position against a 2.5x button open; folding avoids playing a dominated, hard-to-play hand postflop.

K7o is playable as a button open in three-handed poker; a small raise steals the blinds and keeps the pot manageable if called.

5-2 offsuit is the worst hand in hold'em and I'm out of position facing a raise with the big blind still to act. Folding and saving 200 chips is clearly correct.

JTo is playable heads-up vs a button raise; calling keeps pot small while retaining position advantage post-flop is not there, but hand strength justifies a call rather than a fold or raise.

I have an open-ended straight draw (T-J with Q-9-6 board) with 8 outs, so a semi-bluff bet builds the pot and can take it down now.

King-high with only a backdoor club draw has too little equity and showdown value to call a 350 flop bet into 900.

Ace-nine offsuit is a standard opening raise from the button in a 3-handed game; I'll take the initiative and play for the blinds or a favorable flop.

2-6 offsuit is a weak hand facing a raise; folding preserves chips.

Q4 offsuit is too weak to continue against a button open after the small blind folds, so I give up the big blind rather than call or raise.

Cheap price to see a flop with a suited hand in position; not strong enough to raise but fine to call the blind.

84o is too weak to continue out of position for another half-blind against two live opponents. Folding the small blind is the lower-variance choice.

I've already posted the big blind and face no additional bet, so checking costs nothing while folding would surrender my blind for free. With 63 offsuit, raising out of position against a limper adds risk with little edge, so I take the free flop.

I flopped top two pair (sixes and threes) on 3s-6h-Td, so I bet for value and protection against T-x hands and straight draws like 45. A ~60% pot bet builds the pot while keeping worse hands in against a preflop limper.

I have top pair with a weak kicker; a small call is fine here without needing to raise into an unknown range.

I hold bottom two pair on a board with straight possibilities (45 makes a straight), so betting the turn builds the pot and charges draws while I still likely have the best hand against a flop caller.

42s is too weak to open from the button into two live blinds; folding avoids a dominated, low-equity spot.

Cheap price to see a flop heads-up with decent pot odds despite a weak hand.

72o is too weak to raise, and checking is free with no bet to call.

Weak hand with no pair or draw on a dry flop; checking to control pot size.

72o completely missed this flop with no pair or real draw, and the pot is unopened, so checking is the only sensible option.

Weak hand with no pair or draw on a dry board; checking is free and keeps the pot small.

I have 72 offsuit with no pair, draw, or showdown value on a 3-6-9-4 board. With no bet facing me, checking is the only sensible option.

Missed the flush draw, only queen-high; no value in betting, so check it down.

I have complete air on a king-high board and no fold equity worth risking; checking realizes the free showdown.
