Hold'em table

K2 offsuit is too weak to open from the button at these stack depths; folding avoids entering dominated postflop spots.

With the button folded, calling the extra 50 chips lets me see a flop with a connected hand without building a large pot out of position.

82o is weak; checking in the big blind gives a free flop against the small blind limp.

I have a weak hand with little immediate equity on a paired flop, so I'll check rather than build the pot.

The SB limped and then checked, which caps their range. A small half-pot stab on this dry paired board takes the pot often with my air, and a pair of threes is hard for them to have.

Six-five offsuit has little showdown value and only a weak backdoor straight possibility on this paired flop. Out of position, calling the bet is unlikely to be profitable.

J6 offsuit is a weak button open at 100 big blinds, with poor playability when called.

Blind vs blind, Q4o is a reasonable open from the small blind. Raising to 3bb applies pressure and is better than limping out of position.

7-4 offsuit is too weak to defend against a small-blind raise heads-up out of position.

Three-handed on the button, 96o is a marginal but playable steal against two blinds. A small open to 2.5bb puts pressure on them while keeping the risk low.”

T7 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still behind.

T5 offsuit is too weak to defend out of position against a 2.5-big-blind raise.

2-6 offsuit is far too weak to open profitably from the button in this setup.

QTs is strong enough to raise heads-up against the big blind, gaining initiative despite being out of position.

The SB opened to 3bb in a blind-vs-blind spot, so their range is wide. K9o is well ahead of that range, and I'm getting 2:1 with position, which makes a call clearly profitable.

The ace-high flop favors my preflop raising range. A small continuation bet can fold out unpaired hands without committing many chips.

Getting 5:1 against a small, likely range c-bet, K-high with a backdoor spade flush draw and king outs has enough equity to continue.

The third spade is unfavorable for a bluff, and Q-T has only a gutshot to a king with no spade. Checking avoids investing more against a range that called the flop.

With a non-nut flush draw and no showdown value, I take the free river card. Villain's Ax and bigger spade draws won't fold to a bet, so I'll realize my equity cheaply.

Queen-high has little showdown value, but the opponent’s flop call leaves many pairs and flushes in their range. A river bluff is unlikely to fold enough of those hands to be profitable.

K-high has little showdown value against the pocket pairs and Jx that check twice. The spade-heavy runout lets us credibly represent a flush and fold out those better one-pair hands.

Queen-high without a spade is unlikely to beat a river bet on this paired, flush-completing board.

T5 offsuit is too weak to open profitably from the button against two blinds at 100bb.

Heads-up SB vs BB with 54o: a 3x open-raise is standard and profitable given our wide blind-vs-blind range, and it gives us fold equity plus playability.

K6 offsuit is too weak to defend profitably against a small-blind raise heads-up at this sizing.

75 offsuit sits at the bottom edge of a 3-handed button opening range and plays poorly against two blinds at 100bb deep. Folding keeps things simple and costs nothing.

Heads-up from the small blind, A3 suited is strong enough to raise for value and initiative. A 3x open applies pressure while retaining playability.

Nine-five suited is worth defending against a small-blind raise, especially with position after the flop and only 200 more to call.

Betting small protects our equity with a pair and nut-straight draw while keeping worse hands and draws in.

I have an open-ended straight draw and position. Calling the small flop bet lets me see the turn at a good price.

I have only a pair of threes on this coordinated board and little ability to improve uniquely. Checking controls the pot and lets me react to the river.

I have a six-high straight. After the opponent checks, a 700-chip bet can get value from pairs and sets while charging draws.

Our pair of threes is weak on this highly connected board, and the apparent straight draw does not create a winning river because a 5 completes the board straight. Calling the turn bet is unlikely to be profitable.
