Hold'em table

K7s is a clear button open in 3-max; raising builds the pot with position and folds out weaker hands.

Facing a 3bb button open from the small blind with the big blind left to act, K8s is not strong enough to profitably continue out of position.

A8 offsuit is strong enough to defend the big blind against a button open, and calling keeps weaker hands in while avoiding an unnecessary 3-bet.

I have only ace-high with little realistic improvement potential, and the preflop raiser has the range advantage on this king-high flop. I’ll check and keep the pot small.

I have top pair with the preflop raising initiative on a K-T-6 board; betting ~60% pot builds the pot and charges draws while protecting against overcards to my kicker.

A-high has little equity on this board and no meaningful draw. The 400-chip bet is not worth calling without a pair or stronger backdoor potential.

93o is far too weak to open from the button even in 3-handed play.

With only 50 more to call in a blind-versus-blind pot, suited connected 5♥4♥ has enough potential to complete rather than fold or raise.

Pocket sixes heads-up against an SB limper have solid equity, so I raise to build the pot and take initiative rather than checking and letting cheap cards come off.

54 suited has some playability, but calling a sizeable raise from out of position needs more equity than it is likely to have against the raiser’s range.

7-2 suited is too weak to continue against the big blind, even with the button and favorable position.

Suited connector 5s7h has decent playability heads-up; a small raise from the SB applies pressure to the BB and can win the pot or build one with position-neutral odds.

Holding 62s facing a 2.5x open from the small blind is too weak to defend profitably despite having position.

4-5 offsuit is too weak to open from the button even 3-handed, and calling out of position postflop with a marginal connector gives little equity. Folding preserves chips for better spots.

T3o is too weak to complete or raise from the small blind against the big blind, so folding is standard.

T4o is too weak to open from the button, even in 3-handed play.

A7 suited is strong enough to raise from the small blind after the button folds. A raise to 300 applies pressure while keeping the sizing reasonable.

Q9s has solid equity against a wide small-blind steal range, and calling 200 into a 400 pot is cheap with a suited hand that can flop top pair, flush draws, or two-way hands. Folding is too tight and 3-betting OOP with this holding risks bloating the pot without a strong edge.

A small continuation bet applies pressure with ace-high and a backdoor heart draw while risking little on a flop that can connect with the big blind's range.

Top pair nines with a queen kicker is ahead of most of seat_3's flop continuation range, so calling the small 200 bet keeps the pot controlled while protecting my equity; I can reevaluate on the turn rather than inflating against a possible overpair.

I have only ace-high with a modest straight draw, and the turn adds a third diamond to a board my opponent continued on. Checking keeps the pot controlled and lets me realize my equity.

With ace-high, I can beat missed diamond draws but lose to any pair; checking takes the free showdown without risking a bluff into a caller.

I hold trip nines with a queen kicker on a paired board; seat_3's small flop bet and turn check suggest a weaker nine, pair, or missed draw, so a half-pot river bet extracts value while risking little against the rare hands that beat me.

The river bet is small, but my ace-high has no pair and does not block the made diamond flushes or likely value hands. I fold rather than pay off the bet hoping to catch a bluff.

K♣8♣ is a solid button opening hand in a three-handed game. Raise to 2.5 big blinds to take the initiative while keeping the sizing modest.

3s4h offsuit is nearly the worst hand I can hold, and I'd be calling 200 more out of position against a button raise with a third player in the pot. Folding is clearly optimal.

Holding 43 offsuit in the big blind against a button 2.5bb open is an easy fold due to poor equity and reverse implied odds postflop.
