Hold'em table

98o on the button in a 3-handed game is a standard open; raising to 2.5bb takes the initiative and plays well in position against the blinds.

2-10o is a weak hand with poor equity. Folding preserves chips in early position, especially with a small blind and big blind already in the pot.

Heads-up pot with a suited hand; a modest raise applies pressure on BB while keeping my range balanced.

JTo in the big blind facing a 3x open from the small blind heads-up: we have position and good pot odds (200 to win 400), so calling is clearly profitable versus a wide SB opening range.

I have no pair, no draw, and a three-flush board favors a cautious check rather than bluffing into two opponents.

Flush draw plus gutshot gives strong equity; opponent checked as preflop raiser on a scary monotone board, so a semi-bluff bet of 2/3 pot wins often and builds the pot when we hit.

I have no club for a flush draw, no pair, and no real equity against a bet on this monotone flop, so folding is correct.

6-7 offsuit from the button facing a raise-like blind setup isn't strong enough to invest in; fold cheaply.

Button folded, blind vs blind; J7o is a reasonable steal raise from the SB with position disadvantage but fold equity against a lone BB.

Q6o is a weak hand in a raised pot out of position. With only 200 chips to call into a 400-chip pot and facing a 3x raise from the small blind, folding preserves chips for stronger spots.

3-4 offsuit on the button in a 3-handed game is a weak hand with poor playability; folding avoids bleeding chips even though position is favorable.

T8o is a weak hand with poor prospects. Seat 1 already folded, leaving me against the big blind. Folding saves chips when I'm not in a strong position and minimizes expected loss.

Ace-seven suited is a strong hand on the button with position advantage. Raising to 400 chips (3x the big blind) is standard aggression to take down the pot or build value. This puts pressure on the blinds while maintaining a healthy stack.

J3 offsuit is a weak hand facing a raise from the button with another player still to act; not worth continuing.

T2 suited is too weak to defend against a 4x button open from the big blind, even with 300 to call into 550; it plays poorly postflop out of position.

Button folded; heads-up vs BB with a suited but weak hand. Completing for 50 into a 200 pot is cheap enough to see a flop with 83s, while raising OOP with this hand is marginal.

With J7o in the big blind facing a single caller, checking is reasonable to see a flop. The hand has some potential (J-high, gutshot draws possible) and keeping the pot small preflop while out of position is prudent.

I have 3c8c on Tc 2d 9d with just a gutshot and a backdoor flush draw; the pot is tiny and out of position, so checking keeps the pot small and lets me see a free turn.

I have Jack-seven offsuit on a T-2-9d board with no made hand or strong draw. Checking is prudent to control the pot and see the next street at no cost in position against one opponent.

Heads up after villain checked twice on a scary three-diamond board; a half-pot stab with no showdown value folds out most of their checking range cheaply.

With J7o on a diamond-heavy board (Tc2d9d4d), my hand is weak and vulnerable. Facing a turn bet from seat_1 who has shown aggression, calling 100 to win 300 is poor pot odds for a hand with minimal equity against a range that likely contains stronger holdings.
