Hold'em table

A3o is playable as a button open in three-handed poker, so I raise to 2.5bb rather than limp or fold.

With 9d As I have only backdoor flush and gutshot potential; facing a 250 raise over my 50 SB, folding preserves my 100bb stack for better spots.

6-5 offsuit facing a raise with a fold behind me isn't worth defending; folding cheaply.

Calling the big blind with Th is a standard play; I want to see a flop and avoid folding out of position without a strong hand.

A7 suited is strong enough to isolate the limper and take initiative from the small blind with a standard sized raise.

84 suited is too weak to continue out of position against a raise, even with the button limping along. Folding avoids a dominated, low-equity spot.

With 3dTh I have backdoor potential and a ten-high card. Seat 3 opened to 350 from the SB, so a min-raise to 600 applies pressure while keeping my stack healthy for future streets.

A7s has decent equity and implied odds; calling 250 more into a 1050 pot is well-priced against a single re-raiser.

I have the nut flush draw with an overcard on a dry-ish flop, so betting builds the pot and applies pressure in this 3-bet pot.

Calling the flop lead with a backdoor flush draw and overcards to keep the pot controlled while avoiding a big bluff catcher situation.

I only have ace-high with a single gutshot draw and no made hand, so checking to control pot size is best against two opponents who have shown strength.

Board is paired with a flush draw and my hand is marginal; checking keeps the pot small and avoids building a big bet with little equity.

My hand is just ace-high with no pair or draw; better to take a cheap showdown than risk a bluff that could be called by a made hand.

Board is 6s 9h 5d 2d Jc with Th in hand; I have a weak ten-high with backdoor flush draw but no made hand. Both players checked turn, so checking river is the safest play to avoid bluffing into a better hand.

QQ is a strong pocket pair; raise for value from the button to build the pot and isolate against wide blind ranges.

4-2 suited is too weak to continue against a button open to 3.5bb from the small blind. Folding avoids putting more chips in with a dominated, low-equity hand.

4d 8c is a weak hand that plays poorly out of position. Facing a 350 raise with only 250 to call, the pot odds don't justify continuing with such a disconnected, low-equity holding.

95o is too weak to open from the button even three-handed; folding avoids investing chips with a dominated, unconnected offsuit hand.

I have 6h Tc, a weak offsuit hand. The pot is 150 and I only need to call 50, but seat_1 already folded and seat_3 has the big blind. With no reads on seat_3 and a marginal hand, folding is the safest play to preserve my stack.

9h-6c is a weak offsuit hand with no playability. Facing a 100bb pot with a 100bb big blind already committed, calling or raising with this hand is a negative EV decision, so folding is the correct play.

6-3 offsuit is weak; button folded but BB is still in, no reason to invest more with a poor hand heads-up out of position.

Pocket sixes on the button, raise for value and to isolate the blinds with a standard sized open.

92o is far too weak to continue against a button open; folding saves the rest of the stack.

With J-5 offsuit and a 300 raise, continuing is a clear -EV play; folding preserves my stack.
