Hold'em table

On the button with a playable hand in 3-handed play, raising to apply pressure and take advantage of position.

AJo is ahead of a button open and plays well as a 3-bet. Raising to 800 builds the pot and applies pressure before the big blind acts.

I have 6d Ts, a weak hand, and face a significant raise to 800. The pot odds do not justify calling with this speculative hand, so folding is the correct decision.

Facing a large 3-bet with Q8 offsuit, a weak hand that doesn't justify calling or reraising out of position.

Q7o is dominated and too weak to open even on the button, so folding avoids a poor spot.

I have Qc6d, a weak offsuit hand. The small blind has already limped, and I'm out of position with no strong equity, so folding is the most +EV decision.

I hold Qs6d, a weak offsuit hand on the button. The pot is 150 with a 100 big blind to call, giving poor odds, so folding is the most disciplined play.

Heads-up after button folds; 6h7h suited connector plays well as a raise to isolate the big blind.

62 offsuit is too weak to continue against a raise, even heads-up from the small blind. Folding avoids putting more chips in with a dominated, low-equity hand.

Weak offsuit 2-T on the button facing a raise-equivalent situation isn't worth defending; folding preserves chips.

Button folded, so this is heads-up versus the big blind. 98o is connected enough to raise for fold equity and initiative rather than only complete.

I have a pocket pair of deuces, which has decent implied odds if I hit a set. Calling 200 more to see a flop is reasonable given the small pot and deep stacks.

Bottom pair with a weak kicker on a king-jack flop is too thin to bet into the preflop caller, so I check and keep the pot small.

I have a pocket pair of twos on a J-8-K flop with no obvious draw, so I want to see a free card and avoid building a big pot with a weak hand. Checking keeps my options open and lets me react to the turn.

I have a weak pair of eights on a king-jack board and am out of position, so checking keeps the pot small and preserves showdown value.

I have a pocket pair of deuces on a Js-8h-Ks-4d board with no obvious improvement, and the opponent checked twice on the flop and turn, indicating weakness. Checking keeps the pot small and avoids building a big bet with a marginal hand.

I have bottom pair with some showdown value after both streets checked through, so betting is unlikely to get called by worse and folding is unnecessary. Checking realizes the hand cheaply.

I hold a pair of deuces on a J-8-K-4-2 board, which is a weak hand. Both opponents checked through the flop and turn, so I will check behind to avoid building a big pot with a marginal holding.

T4o is too weak to call or open-raise from the button; folding avoids a negative-EV spot.

7h Qh is a weak hand in the small blind facing a 50 chip call. Folding preserves my stack without investing further in a marginal spot.

I hold J5s on the button with no action yet; the blinds are weak and my hand is not strong enough to call or raise profitably, so I fold to preserve my stack.

T2o is a weak offsuit hand heads-up against BB with no fold equity gained from limping; folding preserves chips.
