Hold'em table

9-4 offsuit is too weak to open from the button for a full big blind; folding preserves the stack for better hands.

Seat 1 folded, leaving a heads-up pot with me on the SB holding 7h9d. This is a weak hand out of position, so folding is the correct play to preserve chips.

8c7d is a weak suited connector with no overcards; facing a 100bb big blind and a 50bb small blind, the pot odds don't justify calling with this hand preflop.

J6 offsuit is weak and I'd be out of position against the big blind, so folding the small blind is fine here.

J9 offsuit from the button facing a raise isn't strong enough to continue profitably; folding preserves chips.

42o is too weak to continue out of position against the big blind after the button folds. Folding avoids putting more chips in with a hand that has poor equity and little playability.

K7s is a playable button open in three-handed play. A 2.5bb raise builds the pot in position and can take it down preflop.

My hand (5s 6c) is weak offsuit and unsuited, and I'm out of position facing a raise. Folding avoids investing more chips into a marginal spot.

J4 offsuit is weak, facing a raise with no odds to defend profitably out of position.

I have 2s9c which is a weak hand, and I'm out of position on the button facing a raise. The pot odds don't justify calling with such a marginal hand preflop.

Cheap to complete SB with Q7o heads-up against BB only; not strong enough to raise.

T3s is too weak to raise for value against the small blind's limp, and checking is free with position to realize equity postflop.

No pair, weak hand with Q-high; check to see a free card rather than bet into two players with no equity edge.

I flopped two pair on a dry board and the small blind checked, so a three-quarter-pot bet gets value from worse pairs and draws.

Q-high with no pair or draw on a dry board facing a bet; not worth continuing.

Ace with a kicker on the button, raise for value and to isolate the blinds.

92s is too weak to continue out of position against a button raise, with the big blind still to act. Folding avoids putting more chips in with a dominated, low-playability hand.

I hold 6d 5h, a weak disconnected hand. Facing a 250 raise from the button with only 150 to call, the pot odds don't justify a call with this speculative hand, so folding is the correct preflop decision.
