Hold'em table

9h4s offsuit is a weak hand from the button facing a raise to 100 with two players left to act; folding preserves chips for better spots.

I have a speculative 7-9 suited-ish hand and only need to call 50 to see a flop with a 150 pot, giving me good implied odds if I hit a straight or flush draw.

TsJs suited plays well multiway or heads-up, and I can see the flop for free after the small blind completes. No need to inflate the pot preflop with a speculative hand.

I have a backdoor straight draw with 7h-9d on a J-2-Q board, but no made hand yet. Checking keeps the pot small and avoids building a big pot without strong equity.

I have second pair on a dry-ish flop against a wide limped range that checked, so a small bet gets value from worse pairs and ace-highs while charging diamond draws.

Calling the 140 flop bet with 7-9 on J-2-Q is reasonable; I have an open-ended straight draw and can improve on later streets without overcommitting.

Board is wet with two diamonds and a J-Q runout; my 7-9 is a weak draw with reverse implied odds. Checking keeps the pot small and avoids building a big pot with a marginal hand.

I have top pair with a weak kicker on a three-diamond board with a queen, so checking controls the pot and preserves showdown value rather than betting into a range that can easily be ahead or drawing.

Board is wet with flush and straight draws; my 7-9 is weak and likely behind. Checking keeps the pot small and avoids building a big pot with a marginal hand.

I have only a pair of jacks on a three-diamond board with a queen out, so a river bet is mostly called by better hands. Checking realizes showdown value against the passive opponent.

8c7d is a weak offsuit hand with no pair and poor post-flop playability. Facing a 100 chip raise with only 50 invested by the small blind, folding minimizes losses with this marginal holding.

Button folded, so this is blind versus blind and completing costs only 50 into a 200 pot. Jack-six offsuit is weak out of position, but the price is good enough to see a flop rather than surrender the small blind.

I'm big blind with a suited connector-ish hand (T7s), option to check for free with only one limper, no reason to raise here.

I have jack-high with no pair and no heart on a monotone flop, so checking keeps the pot small and avoids a raise I cannot continue against.

I have bottom-pair sevens on a two-heart flop; betting small protects against flush draws and gets value from worse hands.

J6 offsuit has no pair, no heart, and no draw on a monotone flop, so calling or bluff-raising a half-pot bet is -EV. Folding saves the 100.

J9o is playable as a button open in three-handed poker, and a small raise pressures the blinds while keeping the price reasonable if called.

4-2 offsuit is a weak hand facing a raise; folding preserves chips.

Seat 3 raised to 250 with position; my As-2c is too weak to call or reraise out of position, so folding minimizes losses.

On the button 3-handed with K7 suited-ish offsuit, a standard steal-sized raise applies pressure on the blinds who may fold marginal hands.

I hold 5s6c, a weak hand that is unlikely to improve enough to justify calling a raise. Folding preserves my stack for better opportunities.

J4o is too weak to continue against a button open after the small blind folds. Folding avoids paying 150 more with a dominated offsuit hand.

I have 2s9c which is weak and out of position. The pot odds don't justify calling 100 to play a speculative hand, so folding preserves my stack.

Button folded, so I only need to complete 50 into 150 with Q7o. That price is good enough to see a flop rather than fold or bloat the pot out of position.

Weak offsuit hand (3c Tc) in BB with no raise; checking is free and avoids building a pot out of position with a marginal holding.

Queen-high with no pair or draw has little fold equity worth paying for, and checking keeps the pot small while realizing a free card.

I flopped two pair (tens and threes), a strong hand on this dry board, so I bet for value against the limper.

Queen-high with no pair or draw on 2-T-3; calling 150 is unprofitable against a flop bet.

On the button with A7o in a three-handed pot, an open is better than limping or folding. A 2.5bb raise builds the pot with a playable ace and keeps the sizing standard.

Weak offsuit-ish speculative hand (2s9s) facing a raise with two players to act behind; not worth defending from the small blind out of position.

6d5h is a weak hand that doesn't play well out of position, and calling 150 into a 400 pot with a raiser on the button is too expensive. Folding preserves my stack for better spots.
