Hold'em table

With 4s7d in the button and no prior callers, this is a weak offsuit hand that plays poorly postflop. Folding avoids investing 100 chips out of position against the blinds.

Ace-king is a premium hand in a blind-versus-blind pot. Raising to 3.5 big blinds builds value while charging the big blind to play in position.

84o is far too weak to call a 3.5x raise out of position; folding is clearly best.

Q8 offsuit is strong enough to open on the button three-handed. Raising to 2.5 big blinds pressures the blinds and gives us position if called.

95s is far too weak to call 2.5x three-handed out of position; folding and preserving chips is clearly best.

K3o is a weak offsuit hand facing a 2.5x button raise; calling 150 out of position with a dominated king is unprofitable, so I fold.

73o is too weak to continue out of position against the big blind, even with the small call. Folding preserves chips and avoids playing a dominated hand postflop.

62o is too weak to call a big blind from the button in a 3-handed game, so folding preserves chips for better spots.

J9 offsuit is strong enough to open against a lone big blind. Raising to 3bb pressures weaker hands to fold and gives us the initiative if called.

64o is far too weak to call 200 more against a raise; folding is clearly best.

65 offsuit is below a standard button opening range at 100bb, with weak high-card value and limited flush potential. Without evidence that the blinds overfold, folding is preferable to a marginal steal or limp.

53o is a weak hand heads-up against a big blind who has already invested; folding the small blind is the cheapest option.

Ace-high with a suited ace on the button is worth an open-raise to build the pot and apply pressure; folding is too weak and limping gives up initiative.

T5s is a weak, dominated hand out of position against a button raise with the big blind still to act, so folding avoids investing more chips in a marginal spot.

KJo is strong enough to defend against a button open, calling 200 for a final pot of 650. Calling keeps weaker hands in the opponent's range and avoids inflating the pot out of position.

Middle pair has showdown value, but this ace-high board favors the preflop raiser. Checking controls the pot and preserves the option to call a modest continuation bet.

I flopped top two pair with A2s; seat_2 checked, so I bet for value and protection against draws.

Middle pair with a strong kicker has enough showdown value against a button continuation-bet range to defend at these pot odds. Calling keeps weaker hands and bluffs in without inflating the pot against better hands.

KJ has showdown value but gets limited value from worse hands by leading this paired, ace-high board. Checking controls the pot and keeps the button's bluffs in range.

I hold two pair (aces and nines) on the turn; seat_2 checked, so I bet for value while protecting against draws.

The 600-chip call needs about 23% equity, and KJ can still beat straight draws, newly picked-up heart draws, and other bluffs. Calling keeps those hands in while avoiding an unnecessary raise against aces or trips.

Our jacks and nines have showdown value, but a river bet is unlikely to get called by worse after the opponent bet twice. Check to preserve that value without building the pot against aces, trips, or completed draws.

I hold two pair (A9) on a scary board; seat_2 checked river after calling turn, so a modest value bet can get called by worse aces or jacks while limiting loss if I'm beat.

Despite needing only about 16% equity, this is a weak bluff-catcher against three barrels on a river that completes several draws. My king blocks natural missed-draw bluffs such as KQ and KT, while I hold no heart to block flushes.
