Hold'em table

3d7h is a weak hand with no playability preflop; folding avoids losing chips against two players who have already invested.

KQ suited is strong heads-up against the big blind after the button folded; raising builds the pot with a hand that plays well.

JTo has enough equity and playability to call a single 3x raise in position after the button folds.

Flop is Js5c5d with two overcards and a backdoor flush draw; a small continuation bet builds the pot and can take it down or gain info against a checked-to range.

I have jacks and fives on a paired board against a small flop bet, so I raise for value rather than just call.

I have only K-Q high with no pair or draw on a paired board, facing a large raise indicating strength; folding is correct.

On the button with a suited-ish speculative hand, a standard raise applies pressure to both blinds in a 3-handed pot.

A5o is too weak to continue out of position against a button raise, and a three-bet bluff is poorly structured with the big blind still to act. Folding saves chips for better spots.

5h4c is a weak hand that struggles against a preflop raise from the button. The pot odds don't justify calling 150 to see a flop with such disconnected low cards, so folding preserves my stack.

Pocket eights are ahead of a random button open range in three-handed play, so I raise to 3bb to build the pot and take the initiative rather than flat the big blind.

With 6sTd I have a suited connector that can make strong hands postflop. Seat 3 opened to 300 and I'm in the small blind, so a 500 raise is a standard squeeze play to apply pressure and potentially isolate the opener.

32 offsuit facing a raise and a re-raise is far too weak to continue; easy fold.

Pocket eights are ahead of a small blind min-3bet often enough, and I only need 200 more into 900 while in position. Calling keeps the pot manageable and lets me realize equity postflop.

I have a backdoor straight draw with 6sTd on Ad-Js-2h, but no pair yet. Checking keeps the pot small and lets me see a free turn card without risking chips with a weak hand.

Pocket eights are an underpair on an ace-high board against a preflop 3-bettor. Betting folds out worse and gets called by better, so I check back for showdown value.

Board is paired with two hearts and I hold a weak Ten-high with backdoor flush potential; checking keeps the pot small and avoids building a big pot with a marginal hand.

Pocket eights are an underpair to the ace and jack, and seat 1's preflop raise plus passive lines can still include many better hands. Checking keeps the pot small and realizes a free river.

Board is paired with an Ace and contains two hearts; my 6sTd is weak and likely behind. Checking to the button lets me control pot size and possibly induce a bluff or see a cheap showdown.

Pair of eights is too weak to value-bet on an ace-jack board with three hearts, and a bluff is unlikely to fold out the preflop raiser's better hands. Checking realizes the free showdown.

I have 4d3d on the button with no callers yet. A 400 raise (4x BB) builds the pot, applies pressure to the blinds, and lets me see a flop in position while keeping the stack mostly intact.

A2 offsuit out of position facing a raise with another player still to act is too weak to continue profitably.

Q7 offsuit is too weak to continue out of position against a 4bb button open after the small blind folds. Folding avoids a dominated, low-equity spot.

7-6 offsuit from the button facing a raise-limp situation with weak equity; folding preserves chips for better spots.

34o is too weak to continue out of position for another 50 after the button folded. Folding preserves chips rather than playing a dominated hand against the big blind.

Ten-deuce offsuit is too weak to open even from the button in three-handed play, so folding avoids a dominated, poorly playable hand.

I have Qd4c, a weak offsuit hand, and the big blind has already invested 100. Folding avoids losing more chips with a hand that is unlikely to win at showdown.
