Hold'em table

Q♦8♦ is a reasonable button opening hand three-handed, and a small raise can win the blinds while retaining playability if called.

65 offsuit is too weak to defend out of position against a button raise with the big blind still to act.

A4o out of position against a button open is dominated by too much of the raiser's Ax range, and calling gives poor postflop playability; a 3-bet bluff is too thin with no reads on hand one.

J8o is on the bottom fringe of the 3-handed button opening range; folding avoids playing a marginal offsuit hand.

Heads-up vs the BB, A3o is a standard SB raise — I have an ace, position, and fold equity, and only 50 invested so far. Raising to 300 builds pressure without risking much.

8-3 offsuit is too weak to defend against a 3x raise, especially out of position.

Q7o on the button in a 3-handed game is within a standard opening range, and raising to 2.5bb builds fold equity while keeping the pot manageable if called.

T-8 offsuit is too weak to defend from the small blind against a button raise, especially with the big blind still to act.

T7o is too weak to defend out of position against a 2.5bb button raise.

As the button, pocket deuces are worth opening; a modest raise applies pressure to the blinds while keeping the pot manageable.

J9 offsuit in the small blind against a 3bb button open is a clear fold out of position.

AQo is far ahead of a typical button open range in 3-max, so I three-bet for value out of the big blind rather than calling OOP with a capped range.

A small pair performs poorly against a big-blind 3-bet, and calling 600 would leave me with little room to realize its set-mining value.

T6o is too weak to open from the button even in 3-handed play. Easy fold.

Heads-up from the SB, K2s has decent equity against the BB's wide range plus fold equity; a small raise applies pressure while limiting risk.

J♦8♦ is a reasonable defend against a small-blind raise, and calling keeps the pot manageable with a playable suited hand.

As the preflop raiser I keep the initiative with a half-pot c-bet; king-high has little showdown value but decent fold equity on an ace-high flop against the big blind's calling range.

I have no pair and only weak backdoor draws, so calling the flop bet is not justified. I’ll fold rather than bluff-raise into the aggressor.

43 offsuit is far too weak to play even from the button; folding preserves chips for better spots.

With the button folded, K8 offsuit is strong enough to raise from the small blind heads-up and take initiative against the big blind.

A2o has poor postflop playability and is frequently dominated facing a 3x open from the small blind, making fold the standard play.
