Hold'em table

K3s is a profitable open from the button in 3-handed play; raising to 2.5x to build the pot in position.

ATo is strong enough to continue versus a 2.5bb button open in three-handed play, and calling keeps the pot controlled out of position.

T3 offsuit is too weak to continue against a raise and a caller, even with the pot odds.

I have ace-high and only a gutshot on a king-jack flop, so checking keeps the pot small and lets me see a free card out of position.

We have top pair with a weak kicker, so checking back to control the pot size and under-rep our hand is optimal.

Ace-high with no pair and no draw has little value as a turn bet into the preflop raiser, so I check to realize equity for free.

After checking back the flop with top pair weak kicker, opponent checks turn again, making a delayed value bet targeting weaker pairs and draws sensible.

Ace-high with only a gutshot is not getting the right price to call a turn bet, and raising would be a thin bluff into a player who just showed strength.

Pocket fives is a clear open from the button in three-handed play. A raise to 300 builds the pot and takes the initiative before the blinds act.

Q9 offsuit is a marginal out-of-position defend against a 3x button raise, with the big blind still to act. Folding avoids committing more chips in a difficult multiway spot.

T5s is too weak to defend out of position against a 3x open.

On the button three-handed, J-high has enough steal value to open-raise; a modest raise pressures the blinds without risking much of the stack.

KTo plays poorly out of position from the small blind against a button open, with the big blind still left to act.

78o is too weak to continue out of position against a button raise; pot odds do not compensate for poor playability and domination risk.

87 offsuit is below the standard opening range even on the button in 3-handed play.

Button folded, so I raise 93s from the small blind as a steal rather than limp out of position with a weak suited hand.

J8 offsuit is a reasonable big-blind defend heads-up against a small blind open, and calling keeps weaker hands in without inflating the pot.

I have nine-high with no pair and no draw on an ace-queen board, so there is no value in betting. Checking keeps the pot small and lets me see the turn for free.

I have no pair or meaningful immediate draw, so checking keeps the pot small and preserves my chance to improve.

I have complete air with no pair and no draw on an ace-queen board, so there is no value in betting. Checking keeps the pot small and realizes whatever tiny river equity I have for free.

A small turn bet can take down the pot after two checks; my hand has little showdown value, so I’m using modest sizing to pressure weak holdings.

I have 9-high with no pair and no draw on a queen-ace-deuce board, so calling or raising the turn bet has no equity. Folding saves the 200 chips.

83 offsuit is too weak and disconnected to open or limp from the button, so folding preserves the full stack.

KQo is strong heads-up against the big blind after the button folds, so I raise for value and initiative. A 3bb sizing is a reasonable pressure while keeping weaker hands in.

72o is the weakest starting hand in hold'em and is an easy fold against an SB open.

As the button with a playable suited connector and no raise ahead, I’ll open for a standard 2.5-big-blind raise.

A2o is too weak to call or 3-bet profitably out of position against a button open.

63 suited is too weak to continue out of position against a button open, even heads-up. Folding avoids playing a dominated hand with poor equity.
