Hold'em table

T9s is a playable suited connector on the button, so I open to 2.5bb to build the pot and take the initiative rather than flat the big blind.

J3 suited is too weak to defend from the small blind versus a button open with the big blind still behind.

Q6 suited in the big blind facing a 2.5x button open with SB folded; getting 400:150 pot odds (~27% equity needed), a call is standard and profitable enough to defend.

Monotone heart board with Q6 of spades gives me nothing; out of position against the preflop raiser, checking is clearly best and I'll fold to most bets.

I have top pair on a monotone flop and the BB checked, so a small bet charges heart draws and weaker pairs while keeping the pot manageable.

Q6 offsuit with no hearts on a monotone Th3h5h board has essentially nothing against a button c-bet; queen-high with no flush draw is an easy fold.

7-4 suited is too weak to open profitably from the button in this short-handed format.

Button folded, so I'm heads-up in the small blind vs the big blind with Q2 suited, a reasonable raising hand blind-vs-blind; raising to 3bb takes the initiative and often wins the pot preflop.

67o is too weak to continue against a raise, even heads-up in position. Folding avoids playing a dominated offsuit hand out of the blinds.

On the button in a 3-handed game, 87 offsuit is a reasonable open-raise candidate with position; a 2.5x raise applies pressure on the blinds while keeping the pot manageable.

Q6 offsuit is too weak to continue out of position against a button open, especially with the big blind still to act. Folding avoids a dominated spot with poor playability.

3c5s is too weak to defend against a button raise from the big blind at this sizing.

T3 offsuit is too weak to open even from the button in a three-handed game; folding avoids putting chips in with a hand that plays poorly postflop.

Complete from the small blind with 8-6 suited at a very favorable price heads-up.

8-4 offsuit is a weak hand; button folded and small blind limped, so I take the free flop with position rather than bloating the pot.

This paired, ace-high flop is favorable for a small heads-up continuation bluff after the big blind checked. A minimum-sized bet can fold out many limp-check hands while risking little.

8-high with no pair or draw on a K-K-A board facing a half-pot bet; folding is clearly correct as a bluff-raise has poor fold equity here and calling has no realistic path to winning.

7-5 offsuit is a weak button opening hand in this short-handed spot; folding avoids playing a dominated, low-equity hand.

Pocket eights in the small blind vs only the big blind after the button folds is a clear value raise; 3x sizing builds the pot with a strong hand in a heads-up spot.

95o is too weak to continue against a small-blind raise after the button folds, so I fold rather than call 200.

5s3h offsuit is a weak hand even on the button in 3-handed play; folding avoids playing a dominated, low-equity hand out of position postflop against two blinds.

J4 offsuit is too weak to complete or raise heads-up against the big blind; folding the extra 50 is the lower-variance choice.
