K4 offsuit is playable as a button open three-handed, and a small raise gives me a chance to win the blinds while keeping the pot manageable.

4s2s is a very weak small-blind hand facing a button open, and calling out of position is unprofitable.

Getting 2.67:1 against a wide 3-handed button open, 95o has enough equity to defend from the big blind despite being out of position.

Middle pair with a weak kicker on a K-high two-tone board, out of position against the button's range. Checking controls the pot and lets me see his action before committing chips.

Top pair is likely ahead of the big blind’s defending range. A half-pot bet gets value from weaker pairs and charges spade draws.

Middle pair on a K-9-2 two-tone board facing a small half-pot c-bet from the button. At 3.3:1 pot odds, a call is profitable against a wide button range.

Middle pair on a board where the third spade just fell and a king is out; check to keep the pot small and see whether the button keeps betting.

My top pair has a weak kicker, and the third spade improves part of the big blind’s flop-calling range. Checking controls the pot and keeps weaker hands in for the river.

Middle pair has showdown value against a range that checked back the turn. Betting would mostly fold out missed draws and get called by better hands, so I'll check.

Kings and fours are strong enough for a river value bet after my opponent checked all three streets. A moderate size can get called by weaker kings while limiting losses against a flush.

Getting about 3.2:1 against a small river bet after the turn checked through. Middle pair beats the bluffs and thin value hands in the button's capped range, and my 5h blocks some straights.

Q9 offsuit is a suitable button opening hand in a three-handed game, and raising applies pressure to the blinds while retaining positional advantage.

K8s in the SB facing a button open in 3-handed play: calling out of position with the BB still to act is weak, so I'll 3-bet as a semi-bluff with a suited king blocker. Folding is also reasonable, but 3-betting pressures a wide button range.

Pocket threes are too weak to continue out of position against a 10-big-blind reraise, especially with the button still in the hand.

Q9 offsuit is too weak to continue against a substantial small-blind 3-bet after opening, especially at this sizing.

KTo on the button three-handed is a clear open-raise; 2.5x is the standard sizing to steal the blinds.

A2 offsuit is easily dominated by a button opening range, and calling from the small blind leaves me out of position with the big blind still to act.

7-high suited is too weak to defend against a button raise from the big blind at this sizing.

Pocket fours are worth opening on the button, and a 2.5-big-blind raise keeps the pot manageable while using position.

9-4 offsuit is too weak to defend from the small blind against a button raise with the big blind still to act.

Getting about 3.7:1 in the big blind against a wide button open, so T5o is a standard defend by calling rather than folding or 3-betting.

T5 offhand has only a gutshot (need a 4) on an ace-high board that favors the button's range, so check and plan to fold to a bet unless it's small enough.

Pocket fours have some showdown value but little chance to improve on this ace-high, two-club flop. Checking in position keeps the pot manageable.

The button checked back an ace-high flop, which weakens their range, so a turn probe with a gutshot (any 4 makes a straight) is a solid semi-bluff that can win the pot now or improve.

My pair may still be ahead of a small turn probe, and a five gives me a straight. Calling in position keeps the pot manageable.

Ten-high has almost no showdown value against a range that called the turn, and my 5 blocks some 4-5 straights. A roughly 70% pot bet should get the weak pairs and missed draws that check back flops to fold.

Pocket fours beat missed draws but lose to most pairs and value bets. Calling 800 here requires too many bluffs in the big blind's river betting range.

Q4 offsuit is a weak button opening hand in this configuration and folds rather than enter a marginal pot.

T9s is a strong blind-vs-blind hand, so raising to 3bb from the small blind takes the initiative and avoids playing out of position in a limped pot.

J9 offsuit is strong enough to defend the big blind against a small-blind raise to 3 big blinds, especially with position after the flop.

Top pair with a backdoor flush draw, out of position against the big blind; a small c-bet of about 40% pot gets value and protection against the many draws on this board.

Middle pair with a jack kicker is strong enough to continue against this small flop bet. Calling keeps weaker hands and bluffs in while controlling the pot.

Top pair with a diamond flush draw and a gutshot; betting about two-thirds of the pot gets value from worse pairs and draws and protects my equity out of position.

Top pair with a jack kicker is strong enough to continue against this turn bet. Raising would risk too much against straights and stronger made hands.

Top pair is weak on a four-to-a-straight board where the club flush also completed, so any 8, 3, or club beats us. Checking takes our showdown value without getting raised off the hand or value-owned.

My pair of nines has showdown value, but the river completes several straights and a club flush. A bet is unlikely to get called by enough worse hands to be worthwhile.

T9o is a standard open from the button in 3-handed play, so I'm raising to 2.5bb to take the initiative and keep position.

J3 suited is too weak to call a button raise from the small blind with the big blind still to act. Folding avoids playing a weak hand out of position.

K3 offsuit is too weak to defend against a button open in this heads-up blind situation.
