Hold'em table

Button folded, so this is blind versus blind with A4o. A small raise takes the initiative and denies the big blind a free flop out of position.

Holding Jh Th in the big blind against a small blind raise, I have strong playability and position postflop, making a call well worth the 200 chips.

I have top two pair on a board with a flush draw, so I bet about two-thirds pot for value and protection against the lone caller.

I have no pair, no draw, and no backdoor equity on an Ace-high board facing a solid continuation bet.

Q2o is too weak to open even from the button in three-handed play; it is dominated and plays poorly postflop, so folding is the highest-EV option.

JTo is well ahead of random hands in a blind-versus-blind scenario, so raising to 3bb applies pressure.

AJs is well ahead of a wide SB open after the button folds, so I 3-bet for value and initiative rather than playing out of position with a capped calling range.

Folding JTo out of position facing a 3-bet from the big blind.

Q2o is far too weak to open from the button, even in 3-handed play.

On the button 3-handed, 75o is within a wide steal range; raising to 3x takes initiative against two blinds and I can fold cheaply to a 3-bet.

J6 offsuit is too weak to call a button open from the small blind, so folding is the highest-EV line.

Q5o is too weak to defend out of position against a 3x button open.

74s is playable as a button steal in three-handed; a small open takes the initiative and can win the blinds without a flop.

A2o is too weak to defend out of position against a button open with the big blind still to act.

4h6d is far too weak to defend the big blind against a button raise, especially out of position with poor postflop playability. Folding preserves chips for better spots.

Holding 8d 3h on the button is well outside any reasonable 3-handed opening range, making folding the clear standard play.

Heads-up with only 50 more to call into a 150 pot, the 3:1 odds justify completing with a suited connector-ish hand despite its weakness.

J7o is too weak to raise a limp, and checking is free with position postflop against the small blind.

Open-ended straight draw (any 3 makes the wheel) heads-up in a limped pot; free card is fine, and folding equity is nil.

I have top pair on a wet, draw-heavy flop and the small blind checked. A three-quarter-pot bet charges straight and flush draws while getting value from worse pairs and ace-high.

Open-ended straight draw with 3 or 8 completing it; calling 150 into 350 pot gives good odds with two cards to come.

I hold only 9-high, but checking is free and any 3 or 8 gives me a straight. I can fold cheaply if seat_2 fires again on the turn or river.

I have only a pair of sevens on a connected turn board after getting called on the flop, so checking controls the pot and realizes showdown value without bloating a marginal spot.

I have only a pair of sevens on a king-nine board with a possible straight, so a river bet is unlikely to be called by worse. Checking back realizes the pot without risking more chips.
