Hold'em table

T9o is playable as a button open in three-handed poker; a 2.5bb raise takes the initiative in position rather than limping or folding.

A5s is an excellent 3-betting hand from the small blind against a button open due to ace removal and strong playability.

J♣7♣ is too weak to continue against a substantial three-bet, especially with the button still to act behind me.

T9 offsuit is too weak to continue against a 10bb three-bet; folding preserves chips for better spots.

J2o is far too weak to open raise or play profitably from the button.

T5 suited is a reasonable hand to complete heads-up from the small blind, especially at the favorable price. I’ll avoid inflating the pot with a raise.

QJs is ahead of a typical small-blind complete, and raising builds the pot while I still have position postflop. A raise to 400 is a standard size against the limp.

T5 suited is too weak to continue against a sizable raise, especially out of position. Fold and preserve the remaining stack.

7♦4♥ is too weak to continue against the big blind, even with position and a discounted call.

Button folded, so this is heads-up versus the big blind. A9o is strong enough to raise for initiative rather than just complete.

Facing a 3x open from the small blind, 52s is too weak to defend even in position.

QTo is a playable button open in three-handed poker, so I raise to 3x rather than limp or fold.

With zero rake and excellent playability, calling with T9s from the small blind offers good implied odds against a button open.

K♦2♥ is a weak offsuit hand facing a sizable button raise and a caller; calling out of position risks being dominated and playing a multiway pot with poor equity.

Check to the in-position preflop aggressor with a gutshot straight draw and overcards.

I have top pair with a ten kicker on a dry rainbow flop and the small blind checked. A half-pot bet gets value from worse queens, pocket pairs, and draws while keeping the pot manageable.

I have ten-high with no flush draw and only backdoor straight potential out of position, making this an easy fold against a c-bet.

J2s is too weak to reliably open even from the button in a 3-handed game. Folding is the cleanest standard play.

K-high is strong enough to open-raise heads-up from the small blind. A raise to 300 applies pressure while keeping the sizing modest.

94s is too weak to continue against a 3bb open; even with position the hand is dominated too often and does not realize equity well enough to justify the call.

A7 suited is a strong button-open in a three-handed game; raise to 250 for value and initiative.

J4o is too weak to continue out of position against a button open; folding saves the rest of the stack.

J2o is far too weak to defend the big blind against a button open.
