Hold'em table

Pocket jacks are a strong button hand, so I open-raise to 3x rather than flat the big blind and give the blinds a cheap flop.

8h4d is weak and out of position; facing a 300 raise with only 80 effective stack behind, folding minimizes losses.

Getting 200 to win 650 (about 31% equity needed) in the big blind against a button 3x open, 86o has enough playability to defend by calling.

Middle pair plus a weak backdoor draw, out of position on a K-high board that favors the preflop raiser, so checking keeps the pot controlled and lets me continue against a c-bet.

Pocket jacks are ahead of most of the BB's calling range on K62, and a small c-bet takes the pot down often while charging draws and weaker pairs.

Middle pair with a backdoor flush draw is getting 3.6:1 against a small c-bet (250 into 650), which makes this a clear call and too strong to fold. Raising would only fold out worse hands, so I'll just call.

Middle pair plus a gutshot to the 5 and a backdoor-diamond miss; we're out of position against the button's c-bet range, so check and evaluate. We can call a reasonable bet, since the draws plus the pair give us some equity.

Pocket jacks are still ahead of much of a flop-calling range, and the turn check lets me bet for value against worse pairs and draws while keeping the king in mind.

Second pair facing a small turn bet; getting better than 4:1, so calling is profitable against a wide button barreling range.

Two pair (eights and sixes) beats the top-pair kings this line likely represents, so I lead the river for value. Betting also gets paid by Kx that might check back the scary 8, rather than relying on them to bet a third time.

Pocket jacks is a bluff-catcher on K-6-2-7-8, and 1400 into 3550 only needs about 28% equity. Their passive flop/turn line leaves enough missed hands and thin value that folding is too tight.

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

With 86o in a blind-vs-blind spot, a raise to 3bb is a reasonable open that wins the pot often, and the hand has playable equity when called. Limping out of position would also be defensible.

J7 offsuit is too weak to continue against a preflop raise heads-up from the small blind, so folding is the highest-EV option.

A7o is a clear open from the button in 3-handed play, so I'm raising to 2.5bb to take the initiative and pressure the blinds.

76o is too weak to continue out of position against a button raise, with the big blind still to act. Folding avoids paying 200 into a pot where I am dominated by most continuing ranges.

My hand (2h 8d) is weak and unsuited, and seat_3 has already raised to 250. Folding avoids losing more chips with a dominated hand.

Button open with A3o in a three-handed pot; a small raise steals the blinds and realizes equity better than calling or folding.

I have 7s4s, a weak hand that plays poorly out of position. Seat 1 opened to 250, and I'm in the small blind with only 50 invested; calling 200 more is too expensive for this hand, so folding is the correct play.

99 is well ahead of a button opening range in 3-handed play, so 3-betting for value and initiative from the big blind is standard. A raise to 850 is about 3.4x the open.

A3o is too weak to continue against a 3-bet; folding avoids putting more chips in with a dominated ace.

3s 2h is the worst possible hand and I'm out of position. Calling 50 more to see a flop with no equity is a losing play.

Blind vs blind, T2o is at the bottom of a wide SB range, but a 3x steal or a fold are both reasonable; a small raise leverages fold equity against the big blind.

Q9o is too weak and dominated to continue out of position against a 3x small-blind raise after the button folded.

98o on the button in 3-handed play is a standard open; raising to 2.5bb puts pressure on both blinds.

Pocket jacks are well ahead of a button open, so I 3-bet to build the pot and deny equity rather than flat from the small blind.

I hold Q7s on the button facing a min-raise and a 3-bet to 800. The pot odds don't justify continuing with a weak speculative hand, so I fold to preserve my stack.

98 offsuit plays poorly against a small-blind 3-bet range, even in position. Calling 550 to win 1700 needs about 32% equity, and this hand realizes too little of its raw equity to justify the call.
