Hold'em table

With J7o on the button and no callers yet, folding preserves my 100bb stack for better opportunities.

QJ offsuit is strong in a heads-up pot against the big blind; raising to 300 applies pressure and takes the initiative.

Calling 200 to see a flop with suited 9-7 is reasonable; I don't want to fold out of position preflop and can play the flop if it comes favorable.

Heads-up after my preflop raise, an A-high flop is a good spot to continuation bet; QJ also has a gutshot if called.

Calling is the most straightforward play here. My 9s7s has backdoor flush and straight potential, and the board is relatively dry, so I don't want to overcommit without a made hand. I'll keep the pot small and see if I can improve on later streets.

Board is wet and dynamic with straight and flush possibilities; my 9s7s has backdoor equity but no made hand, so checking keeps the pot small and lets me see a free river. Opponent raised the flop and checked turn, indicating possible weakness or a trap, so I'll control the action.

Board is paired with a Ten on the river and I hold 9s7s, giving me a weak Ten-high hand. Checking is the safest play to avoid building a bigger pot with a marginal holding against a possible strong hand.

KTo on the button is strong enough to open in 3-handed play; raising to 300 applies pressure and uses position to take initiative.

With 5c9d on the button facing a 300 raise, the hand lacks the strength to call or reraise profitably. Folding preserves my remaining 9950 chips for better opportunities.

23s is too weak to continue out of position against a raise, so I'm folding to preserve chips.

I have King-Six offsuit, which is a weak hand. The pot odds don't justify calling 100 chips with this holding, so folding is the most prudent decision.

With the button folded, I have a strong heads-up hand and want to apply pressure while building a pot with an equity edge. A min-raise keeps the risk low and may take it down preflop.

With K8o, I'm out of position and facing a 200 raise after a fold; the hand is too weak to call or reraise, so folding minimizes losses.

23o is a very weak offsuit hand and calling 100 chips out of position against two blinds is not profitable; folding preserves stack.

3h 2d is the worst possible hand and I'm out of position. Folding avoids losing more chips with no equity.
