Hold'em table

Open-raising from the button applies pressure to the blinds and gives this suited-connectivity-adjacent hand a chance to realize equity in position.

I have 7-6 offsuit in the small blind facing a button raise. This hand plays poorly out of position and can be dominated, so folding is the disciplined choice.

4-Ten offsuit is a weak hand with poor equity against a raised pot. Folding preserves chips in a marginal spot against an aggressive preflop raise.

With a small pocket pair on the button, raising applies pressure on the blinds and gives me initiative; I can also flop a set and win a bigger pot.

3c4c is a weak hand with no current value and poor equity against an open raise. Folding from the small blind is appropriate against the button's 3x raise, as this hand plays poorly out of position postflop.

4h2c is far too weak to defend against a 3x button open heads-up out of position.

6d8d is a weak hand (low connectors with poor showdown value). At a 3-handed table, even though there's less competition, the hand lacks the strength to profitably call the big blind out of position. Folding preserves chips for better spots.

9-2 offsuit is too weak to defend from the small blind against the big blind with deep stacks.

AJo is a strong button opening hand three-handed and benefits from taking initiative. A 2.5bb open pressures the blinds while retaining flexibility.

T4o is too weak to defend out of position against a button raise, especially with the big blind still to act. Folding avoids playing a dominated hand with poor postflop potential.

5-8 offsuit is a weak hand with poor equity against seat_1's preflop raise to 250. With no position advantage and only 100 in the pot to call 150 more, folding preserves chips for stronger opportunities ahead.

72o is the worst starting hand and plays poorly even on the button; calling or raising into two active blinds risks chips with very little equity, so folding is the disciplined choice.

T5o is a weak hand in the small blind against one opponent. Folding saves chips and avoids playing a marginal hand out of position postflop.

7-6 offsuit is a weak hand from the button. Folding preserves chip equity against two opponents who have already invested chips in the pot.

K3 offsuit has sufficient heads-up equity to complete from the small blind against the big blind.

K9o is a marginal hand against a small-blind limp; checking keeps the pot small and lets me see a flop in position.

With weak king-high and no heart on a coordinated flop, checking preserves equity and avoids inflating the pot out of position.

Heads-up after the small blind checked, my K-high has an overcard and backdoor flush draw; a small bet can take the pot down or set up later streets.

King-high with no draw has insufficient equity to continue against the flop bet.
