Hold'em table

A3o on the button is a reasonable 3-handed open; raising applies pressure on the blinds and uses position to take initiative.

A9 offsuit is strong enough to three-bet against a button open in a three-handed game. Raising also avoids playing out of position in a multiway pot.

65 offsuit is an easy fold facing an open and a 3-bet.

A3o is too weak to continue against a small-blind 3-bet, especially with the big blind already folded and little chance to improve safely. Folding avoids playing a dominated ace out of position.

T3 offsuit is too weak to open profitably from the button against two blinds.

A7s is a strong suited ace in a blind-versus-blind spot, making an open-raise to 3 bb standard value and steal.

84s is too weak to defend against a small-blind raise out of position, and calling 200 more requires over 33% equity which this hand rarely has against a typical raising range.

Opening from the button with pocket Queens for standard value.

4s2s is too weak to continue out of position against a button raise, and the big blind can still re-raise. Folding avoids a marginal call.

8-4 offsuit plays poorly out of position and is too weak to defend against the button's raise.

9-5 offsuit is too weak to call or raise here; folding avoids investing chips with a poor, easily dominated hand.

With the button folded, calling 50 more is a low-cost way to see a flop heads-up. T6 offsuit is too weak to build a large pot out of position.

Taking a free flop in position with a small pocket pair against the small blind's limp.

I have no pair or immediate straight draw on this dry flop, so I’ll check rather than build the pot.

Holding an underpair on an Ace-Queen high flop in a limped pot, checking back for a free turn card is standard.

I have a straight draw but no made hand. With no bet to call, checking lets me see a river card for free.

I have a weak underpair on a heavily coordinated Broadway board; taking the free card is better than turning my low pair into a bluff.

Ten-high is unlikely to win at showdown. A 150-chip river bet can make some better unpaired hands and weak pairs fold without risking much.

Our pocket threes do not improve the board, meaning we are strictly playing the board's two pair (8s with A-Q-J). Facing a 150 chip bet where opponent likely has a diamond, paired the board, or better, calling merely to chop is negative expected value.

Nine-six offsuit is too weak to open profitably against two players with no reads.

Holding 63o in the small blind blind-versus-blind is far too weak to complete or raise.

Opening 66 from the button with a standard 2.5bb raise.

I have a weak offsuit hand (2d9h) facing a button raise and a 200-chip call, so folding is the best way to avoid playing a dominated hand out of position.

J5 offsuit is a marginal defense against a 2.5-big-blind button raise. Playing out of position makes it difficult to realize enough equity to justify calling.
