Hold'em table

A4 offsuit is a reasonable button open three-handed, with an ace blocker and positional advantage. Raising to 2.5 big blinds pressures the blinds without overinvesting in a marginal hand.

AKo is a premium hand 3-handed against a button open. I 3-bet for value from the small blind with a larger out-of-position sizing.

65 offsuit is too weak to defend against a 9bb three-bet, especially with the original raiser still to act.

A4 offsuit is a weak, frequently dominated hand against a small-blind three-bet. Without evidence of excessive bluffing, folding is preferable to calling or four-bet bluffing.

AJo is a strong hand on the button in 3-handed play, well ahead of blind defending ranges. Raising builds the pot in position and denies free equity.

T4 offsuit plays poorly out of position against a button raise, with the big blind still to act.

Eight-three offsuit is too weak to defend against a 2.5bb button raise. Its poor playability out of position makes calling unprofitable despite the pot odds.

8-2 offsuit is too weak to profitably play from the button against two live blinds.

With the button folded, K7 offsuit is strong enough to open against the big blind. Raising to 3 big blinds applies pressure and offsets the disadvantage of playing out of position.

5-4 offsuit is too weak to defend against a 3x small-blind raise, even in position heads-up.

Eight-four offsuit is too weak to open profitably against two blinds without evidence they overfold. Folding avoids investing in a hand with poor equity and playability.

Heads-up in the small blind, completing for 50 into 150 gives 3:1 odds, and J4o has well over 25% equity against a big blind range.

With a weak offsuit hand and a free option against the small blind's limp, I’ll see the flop without building the pot.

With only a pair of queens and a jack kicker on a paired board, checking keeps the small limped pot controlled and lets me realize showdown value against weaker unpaired hands without risking chips against queens, tens, pairs, or better kickers.

I have no pair or immediate draw, and the small blind has checked. Taking the free card is better than bluffing into a small pot.

With only jack-high on a paired queen board and a checked flop, checking keeps the pot small and takes a free river rather than bluffing into a wide big-blind range that can call with many pairs.

After two checks from the small blind, a modest turn bet can take down the pot with a hand that has little showdown value.

With only a pair of queens and jack kicker on a paired board, I lose to any queen, ten, five, pocket pair, or ace/king kicker, and have no meaningful draw to justify calling 130.

Queen-four suited on the button in 3-handed play has good equity and position, so raising pressures the blinds and builds a pot in position.

K7 suited has reasonable equity against a wide button opening range, and a three-bet avoids playing a weak top-pair hand out of position in a multiway pot.

With 4-2 offsuit facing a large three-bet and the original raiser still to act, calling or bluff-raising would be unprofitable. Fold and preserve the remaining stack.

Q4 suited is too weak to continue against a 10bb 3-bet from the small blind; calling 750 would play a large pot with poor equity and dominated queen potential.

On the button in a three-handed game, Q3 offsuit is a marginal but playable steal. A small raise risks relatively little while giving me position if called.

T3 suited is too weak to defend from the small blind against a button raise, with poor postflop position and the big blind still to act.

2d 9c is a very weak offsuit hand in the big blind facing a button raise; calling 125 would play out of position with poor equity.
