Hold'em table

A9 suited is a strong button hand in a 3-handed game; raising to 300 builds the pot and takes initiative.

Jack-six offsuit is too weak to continue out of position against a button open, so folding avoids a dominated spot.

3d4c offsuit is a very weak hand facing a 3x raise from the button; calling 200 to chase a marginal pot is -EV, so folding is correct.

A6s is a solid button open in three-handed play; raising to 2.5bb builds the pot and applies pressure before the blinds act.

74s is far too weak to defend against a 2.5x button raise out of position; folding avoids playing a dominated marginal hand.

A7 offsuit is a marginal hand but the price to call 150 into a 400 pot heads-up vs a button raise is fine; will play it cautiously postflop.

Ace-high with no pair or draw on a dry board; checking to control pot size.

I have middle pair with an ace kicker and the preflop initiative. A small c-bet gets value from worse pairs and floats while keeping the pot manageable on a wet board.

Ace-high with no pair or draw on a wet-ish board facing a bet; not worth continuing.

J2o is a very weak hand even from the button in 3-handed play; folding preserves chips with no fold equity worth exploiting here.

Heads-up after button folds, a small raise with Q5o applies pressure cheaply and can win the pot outright or take control postflop.

AQ suited is well ahead of a small-blind min-raise, so I 3-bet for value and to take the lead out of position.

Q5o is weak and facing a 3-bet to 700 after my own raise; folding preserves chips rather than continuing with a poor holding out of position.

4-2 offsuit is too weak to continue even in a 3-handed pot facing a call.

Button folded, so this is blind versus blind. Q7o is too weak to flat out of position, but a small raise takes the initiative and can win the pot immediately.

32s is the weakest starting hand and calling 200 more against a 3x raise gives poor equity and bad position; folding is clearly best.

A5 suited is a solid button open in three-handed play, so I raise to 2.5bb to take the initiative and fold out weaker hands.

Pocket queens is a premium hand; I 3-bet for value to isolate the button's open and deny the big blind a cheap multiway pot.

A2 offsuit facing a raise and a big 3bet to 750 is too weak to continue; folding avoids a costly spot out of position.

A5s has enough equity and postflop playability in position to continue against this small-blind 3-bet, and calling 500 into 1100 is preferable to folding or bloating the pot with a 4-bet.

I have an overpair on a dry low board and was the preflop aggressor; betting ~60% pot builds the pot against seat_2's capped range while protecting against draws.

Ace-high with no pair and no draw is too weak to continue against a sizable flop bet from the preflop three-bettor.

Cheap price to see a flop heads-up with a suited connector-type hand.

J8 offsuit is too weak to raise for value against a small-blind limp, and checking is free with no bet to call.

Only bottom pair with weak kicker, no draws worth building the pot; check to control pot size in position-neutral spot.

Jack-high with no pair or draw has little showdown value and poor equity if called, so I take the free card rather than bluff into a limped pot.

I have only a weak pair-less hand with just a low pair draw potential; checking keeps pot small with no strong hand to bet.

Jack-eight has only a gutshot and no pair on an ace-king-ten board, so there is no value in betting. Checking realizes the free river card in a small pot after the opponent showed weakness.

I have two pair (Kings and Fives) with an Ace kicker on the board; after a very passive flop and turn, a modest value bet should get called by weaker hands like a lone ten or ace while risking little.

Jack-high has no pair and almost no showdown value against a river bet on a king-paired ace-high board. The price is not good enough to call with air.
