Hold'em table

K4 offsuit is a reasonable three-handed button open, and a small raise applies pressure to the blinds while keeping the pot manageable.

J7o is an unplayable offsuit hand out of position against a button open.

54o is far too weak to defend out of position against a 2.5x button raise; folding and saving 150 chips is clearly best.

K3o is too weak to profitably open from the button in 3-handed play.

With pocket queens, raise for value and to deny the big blind a cheap flop. A raise to 350 is a solid blind-versus-blind size.

95s is too weak to defend against a large 3.5bb raise from the small blind.

K7 offsuit is a reasonable button open in a three-handed game. I raise the minimum to apply pressure while keeping the risk modest in position.

K4s is too weak to defend out of position against a button open with the big blind still to act behind us.

Ace-Ten offsuit in the big blind against a small 2bb button open is well within defend range; I only need to call 100 into a 350 pot, giving me excellent pot odds to see a flop in position disadvantage but with strong equity.

I flopped top pair with the ace kicker, so I bet around 3/4 pot for value and to charge draws like J-x or gutshots on this connected board.

I have only a gutshot straight draw and a few uncertain overcard outs, which is not enough equity to call this bet. Raising would be a poor bluff on this connected board.

T2o is unplayable even on the button in 3-handed play; folding is the standard and most profitable play.

Ace-King is a premium hand and I'm heads-up against only the big blind; raising for value and position pressure is far better than limping and letting the BB see a free flop.

K♦6♦ is a reasonable heads-up big-blind defend, and calling 200 keeps weaker hands in without inflating the pot with a marginal hand.

I raised preflop and got one caller; a half-pot continuation bet applies pressure with two live overcards and folds out hands like 76 or missed diamonds, while keeping the pot manageable on a coordinated board.

I have a strong flush draw plus a straight draw, so calling 300 offers favorable pot odds while keeping the pot manageable.

Ace-high missed the paired board, but the turn 7 gives me a credible trips/overpair story after flop aggression; a second barrel has decent fold equity against a flop caller, and I can release on the river if called.

I have a strong draw: nine diamond outs plus three non-diamond eights for a straight, with some implied odds if I hit. The price is close, but calling preserves the chance to realize that equity without inflating the pot with a raise.

My Ks-Ac missed the board entirely (only ace-high), so betting or raising has no fold equity justification against an opponent who called two streets. Checking keeps the pot cheap and gives me a chance to win with ace-high if seat_1 was chasing a missed flush draw.

I missed the diamond draw and have only king-high. Checking preserves showdown value against missed draws rather than risking a bluff into a likely pair or better.

Nine-two offsuit is one of the weakest hands in hold'em; folding from the button costs nothing and preserves chips for better spots.

J4 offsuit is weak, but the big blind has not raised and the pot offers favorable odds to complete. I’ll see a flop without inflating the pot out of position.

Taking a free flop in position with a small pocket pair against SB's limp.

With a weak pair and a board offering strong draws, checking keeps the pot small and avoids building it against better hands. I can reassess after the big blind acts.

We hold an underpair on a coordinated Qd Jd 3h board. Checking behind allows us to see a free turn card with minimal risk.

I have a weak top pair on a connected turn that improves many draws, so I’ll keep the pot small and avoid value-owning myself.

I have a weak pocket pair on a heavily coordinated broadway board; checking back keeps the pot small and lets me realize showdown or evaluate the river for free.

I have a weak pair on a connected board, and betting is unlikely to get called by many worse hands. I’ll take the free showdown.}

With pocket fours on a coordinated board containing four overcards to our pair, we have minimal showdown value but little incentive to bluff into an unraised pot. Checking back to realize our equity is standard.
