Hold'em table

A4o on the button in 3-handed play is well within opening range with an ace blocker; raising pressures the blinds and takes initiative.

Ace-king offsuit is a strong value three-bet against a button open. Raising to 1100 compensates for being out of position and discourages the big blind from entering cheaply.

6-5 offsuit is too weak to call a large three-bet, especially with the original raiser still to act.

A4 offsuit is dominated by a large SB 3-bet range and calling 850 out of position equity-wise is poor despite being in position postflop; folding preserves stack.

Ace-jack offsuit is a strong opening hand on the button three-handed. Raising to 2.5 big blinds builds value and pressures the blinds while preserving positional advantage.

T4 offsuit is too weak to defend from the small blind against a button raise with the big blind still to act.

3-8 offsuit is a very weak hand facing a button raise to 250; calling 150 from the big blind has poor equity and playability.

8-2 offsuit is too weak to open from the button, even three-handed.

K7o is well ahead of a big blind's defending range heads-up after the button fold, so raising builds value and applies pressure despite being out of position postflop.

54 offsuit is too weak to profitably defend against a 3bb raise without evidence that the small blind is opening excessively wide. Its limited equity realization makes folding preferable despite having position.

8-4 offsuit is a very weak hand with poor equity and playability, so folding preflop preserves chips.

With the button folded, completing the small blind costs only 50 chips into a 150-chip pot. J4 offsuit is weak, but the favorable price makes a heads-up limp reasonable without inflating the pot out of position.

With 6-4 offsuit against a small-blind limp, I can see the flop for free rather than build a pot with a weak hand.

With only jack-high and weak backdoor straight potential, this hand is a poor candidate to build the pot out of position. Checking preserves chips and lets us reassess against the big blind's action.

After the limper checks, a small bet can fold out unpaired hands. My hand has little showdown value, so checking offers limited upside.

Jack-high with a weak kicker and no direct draw has insufficient equity to continue against this half-pot bet. Playing out of position also makes realizing any marginal equity difficult.

Q4 suited is a reasonable button open three-handed, with position and flush potential. Raising to 2.5 big blinds pressures the blinds while keeping the investment modest.

K7 suited is strong enough to three-bet against a likely wide button opening range. Raising also pressures the big blind and avoids playing a multiway pot out of position.

2-4 offsuit is a very weak hand facing a raise and a 3-bet to 1000; calling 900 has poor equity and no implied odds justification.

Q4 suited is too weak to profitably defend against a large small-blind three-bet, even in position. Folding avoids investing more with a hand that is often dominated and has limited equity realization.

Q3 offsuit is a marginal but playable button open in a three-handed game. A minimum raise risks little while giving me position postflop.

T3 suited is too weak to call a button raise out of position with the big blind still to act; folding preserves stack.

Nine-deuce offsuit is too weak to defend out of position against the button raise, despite the favorable pot odds. Folding avoids investing more with poor equity realization.
