Hold'em table

K3 offsuit from the button facing a raise-limited field isn't strong enough to continue profitably; folding preserves chips for better spots.

Button folded, so this is heads-up versus the big blind. J2 suited is not strong enough to raise, but completing for 50 into 150 is a cheap way to see a flop with suited connectivity.

I'm in the big blind with Qs Ah and no one raised, so checking is free and lets me see a flop cheaply to play postflop.

Jack-high with no pair or real draw has little equity, and checking is free heads-up. No reason to turn this into a bluff.

Checking back keeps the pot small with a weak backdoor draw and avoids building a bigger pot out of position. I'll let the small blind lead if they want to continue.

I have a weak pair of deuces with a jack kicker on a wet turn, so checking keeps the pot small and preserves showdown value.

Checking back the turn keeps the pot small with a marginal gutshot to the 8, avoiding unnecessary risk against a passive opponent.

I have only a weak pair of twos with some showdown value, and the passive opponent is unlikely to fold better or call worse, so checking is best.

Board is dry and I have a weak high-card hand; checking keeps the pot small and avoids bluffing into a likely better hand.

63o is too weak to open from the button; folding avoids putting chips in with a hand that flops poorly and has little equity against continuing ranges.

Seat 1 opened with a 100-chip raise over my 50-chip SB, and seat 2 folded. With AcJc out of position and facing a raise, folding preserves my stack for better spots.

J8o is a weak hand on the button facing a 100bb raise; folding preserves my stack for better spots.

A6 suited is a decent heads-up hand against just the BB; raising builds the pot and applies pressure now that the button folded.

JTs is well ahead of the price to continue heads-up against a small-blind open, and it plays cleanly postflop, so calling is better than folding or bloating the pot preflop.

As the preflop raiser I have range advantage on this dry board; a two-thirds pot c-bet with backdoor flush equity applies pressure and can win the pot outright.

TcJc is just two overcards on a dry 3-8-4 board with no pair or draw, and calling 400 into a c-bet does not have enough equity. Folding is the lower-variance play against continued aggression.

AJ offsuit is a strong button hand in a 3-handed game; raising to build pot and take initiative against wide blind ranges.

Js5o is too weak to continue out of position against a button open, so folding is the highest-EV line.

3s 8c is a weak hand that loses too often postflop, and facing a 250 raise from the button with only 150 to call is not a profitable spot.

25o is too weak to call or raise from the button against two live blinds, so folding preserves chips.

I have As8h, a weak offsuit hand. The small blind has already entered the pot, and I'm out of position. Folding avoids losing chips with a marginal hand that likely won't improve enough to justify calling.

I have King-two offsuit, a weak hand that plays poorly out of position. The pot odds don't justify calling 100 to win 150 with such a disconnected hand.

9-4 offsuit heads-up vs BB with button folded is too weak to continue; folding preserves chips.
