Hold'em table

94o is too weak to open even from the button in 3-handed play, making an easy fold.

Button folded, so I only need 50 more to see a flop heads-up against the big blind. 79o is weak, but the price is good enough to complete rather than fold or inflate the pot out of position.

TJs suited is a strong heads-up hand, and I have position postflop against a limping small blind. Raising to 300 builds the pot with a hand that flops well and takes initiative.

97 offsuit is too weak to continue out of position against a big-blind raise after the button folded. Folding avoids putting more chips in with a dominated, low-equity hand.

87o is too weak to open first-in from the button; it is dominated and plays poorly if called, so folding is the higher-EV default.

Button folded, so it's heads-up vs the big blind and I only need 50 to call into a 150 pot (3:1 odds). J6s has well over the required equity, so completing cheaply and keeping the pot small out of position is the best play.

I check my option in the big blind with T7s to see a free flop in position against the small blind's limp.

Jack-high with no heart on a monotone flop has little value or fold equity against a limping big blind; checking is free and lets me reassess or fold cheaply if a heart or bet comes.

Check back top pair without a flush draw on a monotone board to control pot size and realize showdown value.

I only hold bottom pair with no heart draw on a four-heart board; betting is unlikely to get value, so I check back and reassess on the river.

With second pair and no heart on a four-flush board, checking behind to realize showdown value or see the river is best.

The board ran out five hearts and my best hand is only a pair of sixes (6h6s) with no heart. Any hand that calls a river bet here (a flush, or 7x/Kx) beats me, while the air hands I currently beat would just fold, so checking and realizing showdown equity is better than bluffing into a range that has checked through four streets.

The board contains five hearts, giving both players a flush. Without a heart in hand, betting only risks losing to any holding with a heart, so checking to realize a split pot is optimal.

J9s is a standard button open in 3-handed play with strong positional playability. Raising to 3x applies pressure on the blinds and builds a pot when I connect.

Holding 42o out of position against a button open is an easy fold.

A3 offsuit is too weak to continue out of position against a button open; folding avoids a dominated ace and a poor reverse-implied-odds spot.

King-seven suited is well within a standard 3-handed button opening range, so raising to 2.5bb to build the pot and apply pressure.

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

J4o is far too weak to defend the big blind out of position against a 2.5x button raise; it is dominated too often and plays poorly postflop, so folding is the clean choice despite the small call amount.

92 offsuit is too weak to open from the button even three-handed; folding avoids putting chips in with a dominated, disconnected hand.

Heads-up against only the big blind, Q7s has decent equity and I only need 50 more to see the flop with a 150 pot already built. Calling keeps the pot small while retaining position-equity; raising risks a wide BB defense for little gain.

Holding T3s in the big blind against an SB limp, checking allows us to see a free flop with position.

Queen-high with no draw on a dry 2-T-3 flop; my Q-high may already be best against a wide big-blind range that checked back preflop, so a free turn maximizes cheap showdown value without risking chips on a pure bluff.

I flopped two pair on a relatively dry board and am betting for value against weaker tens and straight draws.

Q7 high on a T-high board facing a check-raise with no equity or reads; cheap fold is best.

A5s is a solid hand on the button; a standard raise to 3x applies pressure and builds the pot with position.

92s is far too weak to defend out of position against a 3x button open.

65 offsuit is too weak to continue out of position against a button open after the small blind folds. Folding avoids paying 200 more with a hand that realizes poorly.
