Hold'em table

A small button open risks little to contest the blinds and gives us position postflop. Although 76 offsuit is marginal, its connectivity provides some playability when called.

K3 offsuit is weak out of position from the small blind against a button raise with the big blind still to act behind. Calling 150 to play a dominated hand is a losing play.

62 offsuit is too weak to continue against a preflop raise, so folding is the highest-EV option.

Queens are a premium hand on the button in a 3-handed pot, so I raise to 3x for value and to build the pot.

86 offsuit is too weak to call a 3bb button raise from the small blind; it is dominated often and plays poorly postflop.

T5 offsuit is too weak to profitably defend against a 3bb button raise out of position. Its poor playability and lack of useful blockers also make a bluff reraise unattractive.

JTo is playable on the button in a three-handed game, so I open to 2.5bb to take the initiative and fold out weaker hands.

K6 offsuit is too weak to defend profitably from the small blind against a 2.5bb button raise with the big blind still to act. Its poor playability and domination risk favor folding.

KQo in the big blind facing a 2.5x button open with 3-handed play: the price is good (150 to win 400) and the hand is strong enough to defend, but not strong enough to 3-bet for value, so I call and play postflop.

Heads-up out of position on a 9-5-3 two-tone flop with two overcards and a backdoor draw. A small bet of about half the pot (300 into 550) gets value from worse hands and folds out some equity-holding hands, and it protects my checking range.

Jack-ten high with no pair and no real draw against a flop donk bet is not worth continuing.

K4 suited is a profitable button open three-handed, with position and suited-hand potential. Raising to 2.5 big blinds pressures the blinds without overcommitting a marginal hand.

2-7 offsuit is the worst starting hand, and I'm out of position in the small blind facing a button raise to 250 with the big blind still to act. Folding costs only the 50 already posted.

J9 offsuit is too weak to continue out of position against a button open; folding avoids a dominated, low-equity spot.

7-8 offsuit on the button in a 3-handed pot is a marginal hand, but it has decent playability and the price is only 100 into a 150 pot. Calling is better than folding, and a raise would be too loose.

Q9o is marginal, but closing the action for half a blind into a 2.5bb pot is cheap enough to complete rather than fold or inflate the pot out of position.

With 5-2 offsuit against two limpers, there is little reason to build the pot. Checking lets me see the flop for free.

Queen-high with no pair and only three clubs total has little equity on a king-high flop, so checking is free and better than bluffing into two opponents.

Bottom pair with a weak kicker has limited value in a three-way pot, and betting is unlikely to get called by many worse hands. Check to control the pot and potentially see a free turn.

On the button after two checks, I have 7-8 with an open-ended straight draw on a 6-2-K board. A small bet of 200 into the 300 pot can take it down now, and I still have outs if called.

Queen-high with no pair and no draw on a king-high flop is too weak to call a 200 bet into a 500 pot.

Bottom pair with a weak kicker and no meaningful draw is a poor defense against a two-thirds-pot bet into two opponents. Out of position, I cannot profitably realize enough equity to justify calling.

Pocket sixes is a solid button open; raising to 3bb builds the pot and takes initiative before the blinds.

Q9 suited is a reasonable three-bet bluff against a wide button opening range, with a queen blocker and useful postflop playability. A four-times raise applies pressure while accounting for playing out of position.

5-8 offsuit is weak and facing a 3-bet to 1200 with a button open behind, calling 1100 more out of position is unprofitable.

Pocket sixes are ahead of a wide small-blind three-bet often enough, and being in position makes a call better than folding or turning the hand into a four-bet bluff.

This ace-high rainbow flop favors my preflop three-betting range, making a small continuation bet an efficient bluff against unpaired hands and weaker pairs. Q9 also has a gutshot to a queen-high straight if called.

Pocket sixes are an underpair to both the ace and ten with no draw, so calling a flop bet from the preflop three-bettor is unprofitable.
