Hold'em table

Pocket fours on the button in 3-handed play is a clear open; raising to 2.5bb applies pressure and builds value versus blinds.

QTo is a reasonable hand to see a flop with versus a button raise, getting good odds in the small blind; calling keeps costs low while retaining position-neutral equity against two opponents.

J4o is too weak to continue facing a button raise and a small-blind call; folding avoids putting more chips in with a dominated offsuit hand.

I have an open-ended straight draw (T-Q needing K or 9) plus overcard potential on a paired board; betting here applies pressure and builds the pot while I have decent equity.

With 4-4 on a J-J-6 flop I have only Jacks and fours, losing to any Jack, six, or higher pocket pair and drawing to two outs against those hands. Calling 300 lacks the equity needed against a leading range rich in those hands.

As button in a 3-handed spot I can open a wide range to apply pressure on the blinds; K5o is marginal but fine for a steal-sized raise.

46 offsuit is too weak to continue against a button open; folding saves chips.

K9o is strong enough to defend the big blind against a 2.5x button raise in 3-handed play, getting good pot odds for 150 more.

With second pair and a king kicker on a Q-9-8 rainbow flop, checking controls the pot out of position against the button raiser and lets me evaluate his bet and the turn.

Continuation bet on a dry-ish board with overcard equity and fold equity against a checking opponent.

Second pair with top kicker on Q-9-8 needs only about 26% equity to call 300 into 850, and is ahead of button bluffs and straight draws.

With second pair and king kicker out of position, checking preserves pot control and lets the preflop aggressor reveal strength, avoiding building a pot against queens or better.

I have king-high with no pair or draw on a dry-ish board; checking back avoids bloating the pot with zero equity while keeping the option to see a free river.

Third pair on an ace river with no ace or club blocker is a poor bluff candidate; checking preserves showdown value against busted draws and weaker pairs that may check back.

I only have king-high with no pair or draw; no reason to bet into a likely-made hand, so I check back.

T6o is too weak to open from the button against two live blinds, so folding preserves chips.

Completing the small blind for 50 into 150 against an unchecked big blind range is cheap; 9-6 offsuit has enough equity and connectivity versus a wide range to see a flop despite being out of position.

KJs is strong enough to isolate the limper with a raise, building the pot while only one opponent remains.

9-6 offsuit is weak and disconnected, facing a 3.5bb raise from the big blind while out of position postflop; calling 250 lacks sufficient equity.

J3 offsuit is too weak even on the button in a 3-handed game; calling the big blind risks dominated postflop spots for little upside.

KQs is a strong hand heads-up vs BB after button folded; raising to build pot and isolate.

J6 offsuit is too weak to continue against a small-blind raise, even with position. Folding avoids playing a dominated hand out of the blinds.

K7 offsuit is too weak to continue facing action from two players, better to fold and wait for a stronger spot.

Button folded, so this is heads-up versus the big blind with KJo. A raise to 300 builds the pot with a strong offsuit broadway and denies the BB a cheap flop.

4-2 offsuit is one of the weakest hands; facing a raise to 300 from the small blind, calling 200 more is unprofitable.

T3 suited is too weak to open from the button even three-handed; folding avoids a dominated, poorly connected hand out of position postflop.

Heads-up against the big blind after the button folded, Q7o is ahead of a random hand. Raising applies fold equity and builds value with the likely best high-card hand despite being out of position.

T4 offsuit facing a 3bb raise with only one opponent to act behind is a weak, dominated hand not worth defending.
