Hold'em table

73o is too weak to open from the button for a full big blind, so folding preserves chips.

72 offsuit has very poor playability out of position, even heads-up against the big blind. Without evidence that the opponent overfolds, folding is preferable to completing or bluff-raising.

K4 offsuit is a marginal button open, but position and a king blocker make a small steal reasonable. Raising to 225 pressures the blinds while limiting investment with a weak kicker.

T8o from the small blind facing a button open, with the big blind still left to act, is a weak out-of-position call. It's not a strong enough bluff-raise candidate, so folding is best.

Q8 offsuit is too weak to defend out of position against a button raise, so folding is the higher-EV play.

J3 offsuit is too weak to open profitably from the button against two blinds at 100bb, so I fold.

Button folded, so this is heads-up versus the big blind. 97o is weak, but 50 to call into 150 is too good a price to fold; a raise is not justified.

A2 suited is a good isolation raise against a small-blind limp, with an ace blocker and nut-flush potential. Raising to 4bb pressures weaker hands while letting us play in position if called.

79 offsuit is too weak to continue out of position against a raise to 400 after only completing the small blind.

58o is too weak to open from the button for a full big blind; folding preserves the stack.

K4 offsuit is strong enough to complete the small blind against a random big-blind hand at 3:1 pot odds. Limping keeps the pot small while out of position with a weak kicker.

62 suited is a weak hand, and checking gives a free flop in a limped pot. I'll keep the pot small and play it after the flop with position on the small blind.

With only king-high and no diamond on a connected, monotone flop, this hand has little equity and poor bluffing potential. Check out of position rather than invest in a weak holding.

Bottom pair with no diamond on a monotone board has modest showdown value but gets little value from betting and is vulnerable to raises, so I'll check and keep the pot small.

With no diamond on a four-diamond board, my king-high hand has little value and no useful flush blocker for bluffing. Checking keeps the pot small and takes a free chance to improve if the opponent checks behind.

Middle pair with no diamond on a four-diamond board gets called mostly by better hands, so checking keeps the pot small and gives a free river.

Top pair has showdown value, but any diamond beats us and worse hands are unlikely to call a bet. Checking avoids inflating the pot against flushes while preserving the chance to win at showdown.

A pair of sixes has some showdown value against a range that checked every street. On a four-diamond board, betting would mostly get called by better hands, so I'll check it down.

A3 offsuit is a profitable button open three-handed, with an ace blocker and position after the flop. Raising to 2.5 big blinds pressures the blinds without overcommitting a weak ace.

Three-handed, the button's opening range is wide, and 97s works well as a polarized 3-bet from the small blind. Raising takes the initiative and avoids playing a passive multiway pot out of position.

9-3 offsuit is far too weak to call a 10bb three-bet or continue against two opponents who have already shown strength.

A3 offsuit is too weak to continue profitably against a 4x small-blind three-bet, even in position. Its domination risk and poor playability favor folding rather than calling or bluff four-betting.

Pocket jacks on the button, first to act in a 3-handed game, is a clear value open. A raise to 2.5bb gets value from weaker hands and keeps the pot manageable if we get 3-bet.

KTo has enough equity against a button open to continue, and calling 200 into 400 is a reasonable price despite being out of position.

J2 offsuit has poor equity realization against a raise and a call, with substantial domination risk. Even with favorable pot odds, defending this weak hand out of position is unlikely to be profitable.

I have top pair plus a spade flush draw on a dry-ish flop, so I bet half pot for value and protection against the button's wide open.

JJ is a strong bluff-catcher on K-Q-4 with two spades against a half-pot lead from the SB, and we have position. Calling keeps the pot controlled and keeps their bluffs and weaker draws in, while raising mostly folds out worse hands and gets called by better ones.

I have top pair plus a spade flush draw on a three-spade board, so I bet about two-thirds pot for value and protection against seat_3.

Our JJ is a bluff-catcher on a scary board, but at 28.6% pot odds, folding is too tight against a donk-leading range that can include smaller pairs, weaker pairs and bluffs. We have little fold equity with a raise, so calling is best.

Top pair with a ten kicker is too thin to value-bet on a three-spade river after seat_3 called two streets; checking controls the pot and realizes showdown value.

JJ has some showdown value against missed draws on this K-Q-3 three-spade board, but betting would mostly get called by Kx, Qx, and flushes and fold out worse hands. Checking back realizes that showdown value.
