Hold'em table

A3 offsuit is a profitable button open three-handed, and a 2.5 big blind raise applies pressure while keeping the pot manageable.

In 3-handed play, A9o is strong against a button opening range. 3-betting to 850 allows us to take the initiative and avoid playing out of position multiway with a medium ace.

6-5 offsuit is weak, and facing a button open plus a small blind 3-bet I would have to call 750 more out of position with no clear equity edge, so folding is best.

A3 offsuit plays poorly against a small blind three-bet, and the 600-chip call is too costly to justify with this hand.

T3o is too weak to open raise or play even from the button in 3-handed play.

A7s is a strong hand heads-up from the small blind against the big blind, since the button folded. Raising to 3bb builds the pot with a hand that plays well and takes the initiative.

8♠4♠ is playable in position against a small-blind open. Calling costs 200 chips and keeps the pot manageable.

I have the nut flush draw plus a gutshot (7-6-5-9 needs an 8) and an overcard ace, so this is a strong semi-bluff. I'm first to act heads-up on a coordinated board, and a bet of about two-thirds pot builds the pot while giving fold equity.

I have a gutshot straight draw, backdoor flush potential, and position. Calling keeps the pot manageable while allowing me to realize my equity.

I have the nut flush draw plus a gutshot (A-high, 7 with 6-5-9 gives 8 for a straight) on the 6s9h5d2d turn, so about 12 outs. Seat_1 only called twice, so betting about half pot builds the pot with a strong semi-bluff and can win right now.

My gutshot has too little equity to call 700 into a pot of 2,100, and the turn bet gives no reason to expect enough implied value.

Queens are a premium hand on the button in a 3-handed game. A 3x raise builds the pot and puts pressure on both blinds.

4♠2♠ is too weak to defend from the small blind against a 3bb button raise, especially with the big blind still to act.

84o is far too weak to defend out of position against a 3x button open.

Nine-five offsuit is too weak to open from the button against two players.

T6o is too weak to complete or raise out of position blind vs blind. Easy fold.

96o is too weak to open even from the button in 3-handed play.

6-3 offsuit is one of the weakest hands. Out of position against the big blind, it isn't worth 50 more chips to see a flop, so I fold.

Pocket sixes on the button in a 3-handed game is a clear raise for value and to take position. A 3x open puts pressure on both blinds.

Nine-deuce offsuit is too weak to defend the small blind against a three-big-blind button raise, especially with the big blind still to act.

J5o is too weak to defend the big blind against a 3bb button open.
