Hold'em table

2s9c offsuit is a weak, unconnected hand on the button facing a raise-call situation; folding preserves chips for better spots.

T5o is a marginal blind-vs-blind hand. Completing for 50 more into a 150 pot is a cheap way to realize equity out of position, and a raise would be thin with this hand.

Td6d is too weak to build a pot from the big blind, but checking realizes its equity cheaply heads-up.

Top two pair on a wet, draw-heavy board in a limped pot; bet for value and to deny equity to spade and straight draws. A bet of about two-thirds pot is a good size here.

Top pair on a coordinated board is strong enough to raise for value and charge spade and straight draws. I can fold if facing major further aggression.

Top two pair on a draw-heavy board (spades, straight draws), so I'm 3-betting for value and protection while charging the many draws in the BB's raising range.

Top pair with a weak kicker is not strong enough to continue comfortably against this large flop three-bet on a coordinated board. Folding avoids committing further against a value-heavy range.

Q9s on the button 3-handed is a clear open-raise; 2.5bb puts pressure on the blinds.

4-6 offsuit is too weak to defend from the small blind against an early 2.5bb open with the big blind still behind.

Weak offsuit holding (4h9c) facing a raise, not worth continuing with a mediocre hand out of position.

7-4 offsuit is too weak to profitably enter from the button at this stack depth.

Heads-up vs BB with Ax offsuit after button folded; raising to build pot and exploit positional/range advantage.

A5o in the big blind against a small-blind 2.5x open is well ahead of a wide SB opening range. Calling 150 into a 400 pot (27% equity needed) is clearly profitable, and I'll have position postflop; 3-betting is a mixed option, but calling keeps his weaker hands in.

I have middle pair with top kicker on a dry-ish board; a continuation bet protects my hand and builds the pot against a likely weaker range.

I have the nut flush draw plus an overcard ace, and I'm getting good odds: 300 to call into a pot of 800. Calling keeps the pot controlled while I'm out of position, and I can realize my equity.

I hold two pair (queens and sevens) with an ace kicker on a paired board, a strong value hand, so I bet to build the pot while opponent's range includes weaker queens or draws.

The small turn bet offers good odds: we need about 28% equity, and minimum defense frequency means we have to defend wide. Ace-high has some showdown value against a barreling range that includes air and weaker draws.

I have two pair, queens and sevens with an ace kicker, likely the best hand given villain's passive calling line; betting for value on the river.

Ace-high is only a bluff-catcher that beats pure air. Against a large triple barrel on a paired board, the villain's range is weighted toward pairs and better, and we also hold the Ad, which blocks some of their busted diamond draws. Folding is better than paying 1800 when we need about 30% equity.

Button raise with suited connector 98s in 3-handed pot, standard sized open.

A6s is a strong hand against a wide 3-handed button open, and the ace blocks the button's strongest hands. Since we're out of position, a 3-bet to 1100 plays better than flatting with the big blind still to act.

Qs2c is far too weak to defend against a 11bb small-blind 3-bet while out of position in a multiway preflop configuration.

Facing a large 3-bet with a speculative suited connector not worth the price here; folding preserves chips for better spots.

74o on the button in 3-handed play is weak and below a profitable opening range against two blinds, so folding is fine.

With 33 in the small blind facing only the big blind, calling completes cheaply and preserves equity in a heads-up pot.

KQs is strong heads-up against a limper; raising for value and to build the pot while isolating.

Pocket threes are strong enough to defend against a likely wide big-blind isolation at this price. Calling preserves implied odds for a set while avoiding unnecessary preflop variance out of position.

With flopped quads on a dry board, checking preserves the opponent's opportunity to continuation-bet or improve enough to put in more money later.

Paired low flop favors the preflop raiser; a continuation bet here puts pressure on a wide calling range that likely missed.

I have flopped quads and should build the pot immediately against the preflop raiser's overpairs, 4x, and possible full houses. A moderate raise retains calls while setting up a large turn pot.

I have king-high with no pair and no real draw on a dry board; facing a large check-raise, folding is correct since my equity is too thin to continue.

7-5 offsuit is a weak button hand and not worth entering with versus two blinds under a chip-maximizing baseline.

Only 50 more to see a flop heads-up with Q5o; cheap enough to call rather than fold or raise with a weak holding.

T4o is weak; taking the free flop in a limped pot is better than raising and inflating the pot out of position.

Weak hand with no pair or draw on this board; check back and look to see a free turn.

Bottom pair with a backdoor club draw in a limped pot, and the small blind checked to me. A small bet of about two-thirds pot takes it down often and protects against overcards.

Qd5c on J64 rainbow board with no equity and facing a bet; not worth continuing.
