Hold'em table

7-4 offsuit on the button in a 3-handed game is a weak, unconnected hand; folding avoids playing a marginal spot out of position postflop against two opponents.

KQ suited is a strong heads-up blind-versus-blind holding after the button folds, and raising builds value while applying pressure to the big blind.

65o out of position facing a 3bb raise isn't worth defending; folding is cheap and preserves chips.

AJo is a strong button opening hand in three-handed play. Raising to 2.5bb builds value while pressuring the blinds.

K2 offsuit facing a raise from the button with a call behind is not worth defending from the small blind.

T3 offsuit is a weak hand out of position against a button open; even with good pot odds it plays poorly postflop, so folding is the standard play.

AJo on the button is a strong hand; raising to build the pot and isolate against limpers.

7s3s from the small blind facing a 3x button open is a clear fold; it plays poorly out of position and lacks the equity to call or 3-bet profitably.

K3 offsuit is too weak to defend against a button 3x raise out of position in a heads-up pot.

3s5c offsuit is a weak hand on the button facing two blinds; folding preflop avoids negative expectation.

7-8 suited plays well heads-up after the button folds and has sufficient equity to raise from the small blind. I use a standard isolation size.

K3 offsuit facing a 3x raise with a player already folded is not worth defending; fold to preserve chips.

T8 suited is a reasonable button opening hand three-handed, with position and suited playability. Raise to 2.5bb to pressure the blinds while keeping the pot manageable.

Weak offsuit T2 facing a raise out of position; not worth continuing.

K3 suited in the big blind facing a 2.5x button open: getting 400:150 pot odds, closing the action, and K3s plays fine enough postflop to defend rather than fold or 3-bet.

K3s missed the Q65 flop; out of position with only king-high and a backdoor flush draw, checking to the preflop raiser is standard and lets me fold or float cheaply depending on the bet size.

As the preflop raiser, a small continuation bet can fold out unpaired broadway and random holdings while risking little. My T-high has some backdoor potential if called.

K3 suited with no pair, no flush draw, and only a gutshot-ish backdoor on Q65 facing a c-bet from the button's open; king-high with weak kicker has poor equity and playability out of position, so folding is the cheapest option.

Pocket tens is a strong hand; raise for value from the button to build the pot and isolate against the blinds.

KJo in the small blind versus a button open at 3.5bb is a solid 3-bet candidate in 3-handed play; raising to 1100 takes initiative and avoids playing out of position in a multiway pot with the big blind.

Q7 suited is too weak to continue against the small blind's large squeeze, especially with the button still behind.
