Hold'em table

97s on the button in a 3-handed pot has good playability and decent pot odds (100 to win 250), so I'll call rather than fold or build a big pot out of position later.

83o is a very weak hand out of position with the big blind still able to raise, so completing the small blind is not profitable.

KTo is a reasonable hand to isolate the limping button with a modest raise, building the pot while I have a slight edge in position-adjusted equity.

9s7s suited connector-ish has good pot odds: 250 to call into 500 pot (about 33% equity needed) and I'm in position on the button against a big blind 3.5x raise. Calling is better than folding or bloating the pot with a 3-bet.

I have no pair or draw on a paired board, so I'll check and control pot size.

Heads-up on a paired J-J-2 board after the big blind checked. I hold 9s7s, which is weak but has backdoor flush and straight outs. A small bet of about half the pot should take the pot often, since a paired board rarely helps the BB's range.

K-high with no pair, no draw, and no fold equity reason to continue against a flop raise on a paired board; the pot odds don't justify a call with such weak equity.

Q2o is a very weak hand, and without any reads on opponents, folding is the best option to avoid losing chips with a marginal holding.

3-6 offsuit is a weak hand; button folded but BB still to act, not worth completing with poor equity and no position.

3-7 offsuit is a weak hand with poor connectivity; not worth calling from the button facing a raise.

J4 offsuit is weak, but the button folded so I'm heads-up against the big blind with only 50 more to call for a 150 pot. Folding is reasonable given I'd be out of position with a weak hand, though calling is close; I'll fold to avoid playing a marginal hand out of position.

J3 offsuit is a weak hand, so I'm folding on the button rather than paying 100 to see a flop out of position against two players still to act behind me post-flop.

K8o is a marginal hand but heads-up against the big blind, raising to 250 puts pressure and can win the pot preflop or take initiative postflop.

AT offsuit is a strong hand heads-up against a single raiser; 3-betting builds the pot and applies pressure.

QJo is a playable hand from the button in a 3-handed game; raising to 250 puts pressure on the blinds and builds the pot with position.

6d9c offsuit facing a raise is too weak to continue profitably; folding preserves chips.

9-5 offsuit is a weak hand. The button raised to 250, so I need to call 150 more to win a pot of 400. I'd be out of position with a poor hand, so folding is reasonable.

J7 offsuit is a weak hand from the button facing a raise; folding preserves chips for better spots.

Button folded, so I'm in the small blind heads-up against the big blind. Completing costs only 50 more to win a 200 pot, which is about 3.0-to-1 odds. 9-6 offsuit is weak but playable at that price.

Facing only a completed small blind with a very weak 42o, I can see a free flop as the big blind and avoid bloating the pot.

Board A-K-A is very strong for the range of a limped BB, and I hold only 9-high with no draw. A bluff has poor odds against hands that connected with an ace or king, so I check and take the free card.}

My hand is extremely weak (2-high) with no pair or draw on this paired board; checking keeps the pot small and gives me a free card to possibly improve.

Board is Ad Kc Ah Qd and I hold 9d 6c, which is just a weak flush-draw-free hand with no pair. Both players checked the flop, so betting risks only getting called or raised by better holdings. I'll check and take the free card.

Seat 1 has checked twice and the board is scary; I have no showdown value, so I bet half pot as a bluff to take down the pot.

I have 9-high with no pair, and the board of A K A Q is strong for the BB's range after two checks. Calling 100 into a 300 pot is only about 25% equity needed and I have almost none, so folding is best..
