Hold'em table

Button opening with ATo is profitable three-handed; a 2.5bb raise applies pressure while retaining flexibility.

5-3o is a weak hand with poor win rates. Against a raise to 250 from seat_1 and the big blind still to act, folding preserves chips in an unfavorable position with marginal holdings.

Ks6h offsuit isn't strong enough to 3-bet from BB against a min-raise, but it's cheap to see a flop for just 150 more chips.

King-high with a backdoor draw only; checking to control pot size and see what the preflop raiser does.

I will make a small continuation bet to pressure weaker unpaired hands while retaining an efficient bluff size on this coordinated flop.

King-high with no pair or draw on a Jack-high board facing a continuation bet; not worth continuing against two opponents' actions.

Weak offsuit low cards (2-3), button folded, only BB to act; not worth completing with a poor hand.

K2 offsuit is a weak button hand facing a call; folding preserves chips for better spots.

With the button folded, pocket fours are strong enough to open heads-up from the small blind and can win immediately or play well against a defense.

Q2 offsuit is a weak hand, and facing a raise to 250 from the small blind (seat_1) while in the big blind, folding is the prudent play. With only 150 to call and poor equity, it's not worth continuing with such a marginal holding.

On the button in a three-handed game, 5-3 suited is playable as a low-frequency steal/open and retains postflop equity.

AK is a premium hand. Seat_1's raise to 250 suggests strength, but with AK I have excellent equity against most ranges. A strong 3-bet to 1000 builds the pot while gaining information and applying pressure preflop.

A5 offsuit facing a raise and a big reraise to 1000 (10bb) is too weak to continue; folding preserves chips against likely stronger hands.

3d5d is far too weak to continue against a large 3-bet, especially out of position in the resulting heads-up pot.

King-four offsuit is a weak hand in early position with no fold equity advantage. Folding preserves chips for better opportunities rather than investing in a marginal situation.

A8 suited is a strong hand in this near-heads-up spot with the button already folded, so I raise for value and to isolate the big blind.

KQo is a strong heads-up blind-versus-blind hand and benefits from building the pot while applying pressure to the small blind's opening range.

Weak offsuit hand (3h9s) with no pairing potential and poor connectivity; not worth calling from the button against two live blinds.

KJs suited is strong heads-up from the small blind after the button folds. Raising applies pressure and builds value against the big blind's wide defense.

K6o is a weak hand, and facing a 3x raise out of position as big blind, folding preserves chips for stronger situations where I have better leverage.
