Hold'em table

K3 offsuit is a marginal hand, but on the button in a 3-handed game it has enough equity and fold equity to open for a small raise, so I chose 250 over folding or limping.

J2 suited is too weak to defend from the small blind against a button raise with the big blind still to act.

Holding AQo in the big blind against a button open in 3-handed play is a standard 3-bet for value.

K3 offsuit is weak and facing a 3-bet to 1000 from the big blind, calling 750 out of position-less but with a dominated hand is unprofitable; folding is the disciplined choice.

6-3 offsuit is too weak to open from the button against two opponents.

AJs is a premium hand blind vs blind; opening to 3bb builds the pot and exerts pressure.

A4s is a reasonable defend in the big blind against a small blind 3x raise in a 3-handed game. I'm getting good pot odds and have the ace, so I call rather than 3-bet out of position.

Check out of position on a coordinated board with two overcards and backdoor equity to control pot size.

Ace-high with a backdoor nut flush draw and a wheel gutshot on a dry 2-T-8 board, heads-up after the SB checked. A small bet of half the pot takes the initiative and could fold out hands like 9x or a small pair, while keeping the pot manageable.

Getting 3-to-1 pot odds on the flop, calling with two overcards and backdoor flush/straight draws is standard.

I have Ace-high with two overcards out of position; checking is the standard play to control the pot size.

I have the nut flush draw plus a wheel draw (4-3-2-A gives an open-ended straight draw with a 5 needed) on the turn, and the opponent checked twice, showing weakness. A half-pot bet earns fold equity, and I keep strong equity if called.

I have only Ace-high with no strong draw on a board where the opponent has bet both the flop and the turn. Calling 500 into a 1700 pot without sufficient equity or river position is unprofitable.

J8o is on the weaker fringe of 3-handed button opening ranges, so folding avoids marginal postflop situations.

Ace-x suited in the small blind heads-up against the big blind, with the button folded, is strong enough to raise for value and to take the initiative. A 3x raise is a standard size.

J♣T♣ plays well in position against a small-blind raise. Calling keeps weaker hands in and gives this suited connector room to realize its equity.

Ace-high with a nut flush draw's cousin: A6 of spades plus a gutshot-ish wheel draw (A-3-4-6 needs a 2 or 5 for a straight, 5 gives 3-4-5-6 plus 8 no; 2 makes A-2-3-4 with 6?). Heads-up in position out of position, a bet of about two-thirds pot builds the pot and gets folds from worse, with backdoor spade and straight outs as equity.

J♣T♣ has two overcards and backdoor straight and flush possibilities. Calling in position keeps the pot manageable against a range that may include missed high cards.

I have A-6 of spades with a gutshot to a straight (5 makes 3-4-5-6-7-8) plus a nut flush draw on the 3d 8c 4s 7s board. Any 5 gives a straight, and any spade gives the nut flush, so I'm well ahead of a calling range with about 15 outs. I'm first to act heads-up, so a semi-bluff bet of about 65% pot builds the pot and can win right away.

J-high with only a gutshot has insufficient equity to call 900 into 2300 against a second barrel, and this is a poor spot to bluff-raise.

AJo on the button in a 3-handed game is a strong hand, so a raise to 3bb takes the initiative and puts pressure on both blinds.

J5 offsuit is too weak to defend from the small blind against a 3x button raise, especially with the big blind still to act.

83o is completely unplayable against a button open, easy fold.

5-2 offsuit is too weak to open from the button against two unknown opponents.

A8o is well ahead of an average random holding; raising to 300 from the small blind puts pressure on the big blind.

A4o suited with an ace is a good hand in 3-handed play. The small blind raise to 300 is likely wide, and I'm getting 2:1 on a call from the big blind, so I'll call and play postflop.

C-betting 1/3 pot on a dry King-high board where our preflop raising range has a strong equity advantage, holding overcards and a gutshot to the wheel.

Bottom pair with an ace kicker and a backdoor wheel draw, facing a small 200 bet into 600. Pot odds are good and a raise would mostly get called by better hands, so I call and keep the pot small.

I have Ace-high with a gutshot draw to the wheel (needs a 5). Checking to control pot size out of position.

I have a pair of fours with an ace kicker on a 4-K-3-2 board, plus a gutshot-to-wheel draw (A-2-3-4 made a straight draw needing a 5). Actually A,2,3,4 gives a wheel draw needing a 5, so I have a pair and a draw. Seat 3 checked the turn after betting the flop, so a modest value/protection bet of half pot is reasonable.

I only have Ace-high with a gutshot straight draw (four outs) facing a half-pot bet, which does not offer sufficient pot odds to continue.

K2o is too weak to open profitably from the button even in 3-handed play.

9-4 offsuit is a weak hand, and out of position against the big blind I would rather give up the 50-chip small blind than play a marginal pot.
