Hold'em table

Pocket aces on the button; standard open to 2.5bb to build the pot while keeping blinds in with worse hands.

63 offsuit is too weak to defend against a button raise from the small blind, with poor equity realization out of position and the big blind still to act.

Defending JTo in the big blind against a standard 2.5bb button open getting roughly 27% pot odds.

I flop a gutshot straight draw with two overcards out of position; checking to the preflop aggressor is standard.

Pocket aces on a wet 6-9-7 two-club board; bet ~2/3 pot for value and protection against draws after BB checks.

I have two overcards and a gutshot to the nut straight. Getting roughly 3.5 to 1 pot odds with good implied odds makes calling profitable.

Turned top pair with a gutshot straight draw out of position. Checking is standard to control pot size and keep opponent's bluff range wide.

Overpair on a wet board where the BB's flop-calling range includes many draws and pairs; a ~65% pot bet charges flush/straight draws and extracts value from Tx/9x/8x hands while keeping the pot manageable if raised.

Turn gives us top pair and an open-ended straight draw. Calling the 850 bet is very profitable with our equity and pot odds.

I have a pair of tens on a coordinated board with straight and flush possibilities, so checking to realize showdown value or evaluate facing a bet is optimal.

River completes the flush and 8x straights; villain's check-call-check line on this board is heavy with draws that got there and pairs that won't call a third barrel. One pair of aces is a check-back to realize showdown value without facing a check-raise.

Seven-three offsuit is too weak to open profitably without evidence that the blinds overfold. Folding avoids investing in a hand with poor equity and playability.

84s is too weak to complete or raise from out of position against the big blind.

T3o is far too weak to open on the button even 3-handed. Folding is standard.

Button folded, so it's SB vs BB heads-up. J8o is a reasonable raise from the SB in a blind-vs-blind spot; raising takes initiative and often wins the pot preflop, while limping invites the BB to attack.

Calling costs 200 to contest a 600-chip pot, requiring 33.3% equity. Q6 offsuit is a reasonable defense against a typically wide small-blind opening range, especially with position postflop and no rake.

Dry Q-high board favors the preflop raiser's range; a small 1/3-pot c-bet with backdoor straight equity and two overcards-ish folds out many hands cheaply.

Top pair is comfortably strong enough to call a one-third-pot bet against a wide small-blind opening range. Calling in position keeps bluffs in and avoids building a large pot with a weak kicker.

Ace on the turn is a strong scare card for the preflop raiser's range; double-barreling with air to fold out pocket pairs, 7x, and weak Qx, with a river shove option if called.

The ace is a natural barrel card for a wide small-blind opening range, so a pair of queens still beats plausible bluffs. Calling costs 650 into 1,650, and we can reassess in position on the river.

Jack-high missed everything; villain called two barrels on an ace-high board and likely holds Ax or better, so a third bluff needs too many folds to be profitable. Give up and check.

Second pair with a weak kicker has showdown value, but a bet is unlikely to get called by enough worse hands. Checking avoids paying off an ace or a better queen while still beating missed draws and bluffs.

AQo on the button in a 3-handed game is a clear value open; raising to 2.5bb puts pressure on the blinds and builds a pot in position.

76 offsuit is too weak to defend profitably from the small blind against a 2.5bb button raise, especially with the big blind still to act. Its poor equity realization out of position makes folding preferable.

Q7s has sufficient equity and playability to defend against a standard button open getting almost 2.7 to 1.

Check to the in-position preflop raiser with middle pair second kicker.

Standard c-bet with AQ overcards on a dry 8-2-7 board after BB checks; we have range advantage and fold equity against many hands, plus outs if called.

I have middle pair with a strong kicker on an uncoordinated board and am getting favorable pot odds against a standard button continuation bet.

I hold third pair on an Ace turn after calling a flop c-bet. Checking is standard to control pot size and see how the aggressor acts.

Turned top pair with a strong kicker on a dry board; betting ~65% pot for value against pairs, 8x/7x, and draws like 65/T9 that called the flop c-bet.

The turn brings an Ace which favors the preflop raiser's range; third pair cannot profitably continue against a double barrel.

63 offsuit is too weak to profitably open from the button against two opponents without evidence that they overfold. Folding avoids investing chips with poor equity and playability.

T9o plays well in blind-versus-blind confrontation; raising to 300 exerts immediate pressure and secures initiative.

T3 suited in the big blind facing a 3x raise from the small blind with button folded; I'm getting 200 to win 400 (3:1 odds) and will be in position postflop, so a call is reasonable with a suited hand.

C-betting one-third pot on an Ace-King-Eight board heavily favors my SB opening range and lets me apply pressure with a gutshot.

T3 suited missed the AK8 flop completely with only a backdoor flush draw; facing a one-third pot c-bet from the preflop raiser on a board that smashes their range, folding is clearly correct.

53s is at the very bottom of the button range in 3-handed play; folding is standard and preserves chips.

9-4 offsuit is a weak hand out of position against the big blind; completing or raising has negative expectation, so I fold and lose only the small blind.
