Hold'em table

78o is weak, but on the button three-handed a small 2.5x open attacks the blinds and I retain an easy fold if either blind plays back aggressively.

7-5 offsuit is too weak to defend out of position against a button raise, even with the small blind already invested.

Getting 2.7 to 1 odds closing the action against a button open, J6s has sufficient equity and playability to defend.

I flop top pair with a weak kicker out of position on a coordinated board, so checking to the preflop aggressor is the standard play.

As the preflop raiser heads-up against a checked big blind, a half-pot continuation bet with second pair plus a gutshot takes initiative, folds out weaker ranges, and still has outs when called.

I have top pair with a weak kicker on a coordinated board, which is sufficient to call a half-pot c-bet getting 3:1 pot odds.

I have two pair with Jacks and Nines but a weak kicker out of position, making check the most standard pot-control play.

I hold two pair, Jacks and Nines. Betting is unlikely to get called by worse hands, while checking allows me to realize showdown value or induce bluffs.

My 8c gives me eights full of nines (88899), beaten only by quads or nines full, while seat_3's check-call flop, check turn, check river line looks like jacks, nines, or two pair. A ~2/3 pot value bet of 700 into 1100 extracts from all those worse hands.

I hold Jacks and Nines on a double-paired board, which beats all bluffs and missed draws. Getting nearly 3.5-to-1 pot odds, calling is standard against a polarized river bet.

T9 offsuit is playable from the button in a three-handed game, so I’ll raise for value and initiative rather than limp.

K7o is too weak to defend out of position from the small blind facing a button open.

Q9o in the big blind gets a cheap price (150 into 400) against a wide button open in 3-handed play; my equity well exceeds the ~27% needed, so I take a flop despite being out of position.

I whiffed the flop with just queen-high against the preflop raiser, so checking is free and preserves the option to fold if he bets.

I have no pair and only weak backdoor possibilities on a low, connected board that likely favors the big blind's calling range. I’ll take the free card rather than bluff with little equity.

Queen-high with no equity against a preflop raiser who checked back the flop; betting here risks chips I can't win at showdown, so I keep the pot small and reassess on the river.

I have only ten-high and no meaningful draw on this low, connected board. Checking preserves showdown value and avoids bluffing into a range likely to contain pairs.

The river ace favors my preflop raising range, and my ten-high has little showdown value. A modest half-pot bluff may fold out missed overcards and some weak pairs after the opponent checked through the earlier streets.

I hold only Q-high; the preflop raiser betting the river after an ace hits is very unlikely to be beatable, so folding is cheapest.

J2o is too weak to open profitably even on the button in a 3-handed game.

Button in 3-max with K8o is worth a standard open for fold equity and position; a min-size-plus raise keeps risk low while applying pressure to blinds.

J7 offsuit is too weak to call a 3x button raise from the small blind, especially with the big blind still to act.

Q2s is too weak to defend out of position against a 3bb button open.

KQo is a strong button hand in a three-handed game, so I’ll open-raise for value and initiative.

J3o is far too weak to defend out of position against a button raise.

Jack-four offsuit is far too weak to defend the big blind against a 2.5bb button raise; it flops poorly and plays badly out of position. Folding is the clear profitable line.

Opening from the button with J9o to steal the blinds or play in position postflop.

K4s is far too weak to call a 2.25x raise out of position; folding is the clear plus-EV play.

3♠4♣ is a very weak offsuit hand, and calling out of position against the button raise risks poor postflop realization despite the pot odds.
