Hold'em table

T6o is a weak hand in early position (on the button facing a big blind raise). Folding preserves chips against unfavorable odds, as this hand has poor equity against a likely stronger range.

JTs is a strong enough hand to raise against a single big blind after the button folds, taking initiative and often winning the pot preflop or building value when called.

K4 offsuit is a weak, dominated hand versus a small-blind raise, and calling out of position is unlikely to be profitable.

T7s is a reasonable button open in 3-handed; raising applies pressure and takes initiative with position.

JTs? Actually JTo has sufficient equity to defend against a button 2.5bb open in a short-handed pot, despite being out of position.

9-2o is the worst hand in poker. With a raise and call ahead of me from the button and small blind, folding is the correct play to minimize losses.

I have top pair with a strong kicker on a wet board and should bet for value while charging heart draws and straight draws.

I have top pair with a weak kicker and position. Calling keeps the pot manageable and allows me to evaluate the turn; raising would only get called by better hands or strong draws.

Betting top pair with an open-ended straight draw extracts value from worse pairs and draws while charging the substantial heart-draw portion of the opponent's range.

Q3 offsuit is a weak button opening hand in this short-handed spot and folds cleanly to avoid marginal postflop situations.

9-5 offsuit is a weak hand in the small blind. With seat_3 already folded and facing a 50-chip call to a 100-chip big blind raise, folding this marginal hand preserves chips for stronger opportunities.

AJo is strong in a blind-vs-blind spot after the button folds, so I'll raise for value and take initiative.

Fold the very weak offsuit 4-3 facing a small-blind raise; it lacks sufficient equity or playability out of position.

5-7 offsuit is too weak to continue profitably here; folding preserves chips with no investment.

Complete the small blind with a suited hand that has reasonable heads-up playability, while keeping the pot small out of position.

I have T6o in the big blind facing a small blind call with one fold. Checking is appropriate here to see a flop cheaply with a weak hand, as it avoids putting more chips at risk preflop in an unfavorable spot.

With bottom pair on an ace-high board in a limped pot, checking keeps the pot controlled and allows us to evaluate later action.

I have a pair of tens on A-4-T flop, which is a solid hand. With my opponent checking, checking back allows me to see the turn while controlling pot size. This prudent line avoids overcommitting with a medium-strength made hand against an unknown opponent.

I bet small for protection and thin value with my pair of fours after both players checked the flop. This can fold out unpaired overcards while keeping weaker draws and pairs involved.

I hold Td6s with a pair of tens on a board of Ah4c10c7d. Seat 3 raised to 100 on the turn after we checked the flop. My hand is vulnerable and not strong enough to justify a call or raise against aggressive action from a position where they showed strength. Folding preserves chips for better spots.

Q6 suited is a profitable button open in a three-handed game, leveraging position and initiative.

9-3 offsuit is too weak to defend out of position against a button raise; calling 100 more with poor equity and reverse implied odds is not profitable.
