Hold'em table

JTo on the button in 3-handed play is a strong opening hand; raising applies pressure to the blinds and builds pot in position.

A7o in the small blind against a 3-handed button open is too strong to fold, and calling out of position with the big blind still to act is awkward. A 3-bet to 10bb plays well thanks to the ace blocker and fold equity.

Facing a big 3-bet to 1000 with a weak suited 86 offsuit-ish hand (86 suited hearts), not worth calling 900 more out of position against a strong range.

JTo offsuit is dominated by the small blind's large re-raise range and does not have enough equity or playability to call 750 more out of a 100bb stack.

KTo is a strong opening hand on the button in 3-handed play, so a standard 2.5bb open is the play.

T3 offsuit is a weak hand facing a raise; folding is correct given poor equity and position.

Q6 suited has sufficient equity against a wide button open for 150 more into 400, despite being out of position.

Top pair with a weak kicker on a draw-heavy board; checking controls the pot and lets me evaluate against the preflop raiser rather than building a pot out of position.

In position with a gutshot to the nut-ish straight (J) plus a king overcard, so a small c-bet gets folds and builds the pot with equity behind it.

Top pair on a draw-heavy board facing a small flop bet; calling gives good pot odds and keeps the pot controlled out of position with a weak kicker.

Trips with a weak kicker on a three-spade board; checking controls the pot and avoids raising into flushes or better queens while keeping worse hands in.

K-high with a gutshot on a paired board where the flush just completed. A bluff here is unlikely to fold out the 9x and 7x hands that called the flop, so I'll take the free card to the river.

I have Queens full of Sixes, beaten only by Q9/Q7, so I lead for value against flushes, straights, trips and pairs that would check back.

King-high with no pair cannot call a large river lead, since we need about 44% equity and would beat only busted draws. The opponent's range is mostly made hands.

Button raise with suited-connector-ish TJ offsuit, decent position and fold equity against blinds.

2c 8h is a very weak offsuit hand facing a button raise to 250; calling 200 from the small blind is unprofitable.

QJo in the big blind facing a 2.5bb button open is a clear defend: we only need 150 more into a 400 pot. Flatting keeps the button's wide range in, and 3-betting has less value with this hand.

QJ on 9-5-T with a diamond draw gives an open-ended straight draw plus a backdoor flush draw. Out of position against the preflop raiser, checking keeps the pot controlled and leaves room to check-raise or call his c-bet.

Top pair with a strong kicker on a dry-ish board; betting for value after check gets called by weaker tens, pairs, or draws.

QJ on 9-T-5 two-tone gives an open-ended straight draw, a backdoor flush draw with the Qd, and overcards. Calling 300 into an 1150 pot is clearly profitable, and calling keeps the button's weaker hands in.

QJ has an open-ended straight draw plus two overcards. I'm out of position against the preflop raiser, so I'll check and plan to call a reasonably sized bet with good equity.

Top pair with a good kicker on a wet-ish board; betting for value and protection since villain has been passive.

With QJ on 9-5-T-6 I have an open-ended straight draw: any K or 8 makes a straight, about 18% to hit on the river. Overcard outs and implied odds with deep stacks make calling 700 into 2,550 (27.5% needed) worthwhile.

Queen-high missed the draw and has almost no showdown value, and a river lead against a range that has barreled twice would rarely get better hands to fold. I'll check and give up if they bet.

I likely have the best hand with top pair/Jack kicker; a moderate value bet should get calls from worse pairs while avoiding folding out their range.

The gutshot missed, so I only have queen-high on a board where the button has bet every street. A call needs about 25% equity, and Q-high rarely beats a value-heavy three-barrel range.

Three-handed on the button, T8o is within a wide opening range and has position postflop. Raising applies pressure to the blinds and gains initiative over just calling.

42o in the small blind facing a button open, with the big blind still to act, is a clear fold. Calling out of position with one of the worst hands isn't profitable.

5d8d suited but weak offsuit-gapper value facing a raise with only marginal implied odds; folding is fine against a min-raise with a speculative hand out of position.

J8 offsuit is a profitable button open in 3-handed play against two blinds, so I'm making a standard 2.5bb steal.,

AQo is a strong value hand against a wide button open, dominating many of his continuing hands. A 3-bet to 800 builds the pot heads-up and denies him cheap position.

J8o is too weak to call a 3-bet to 8bb, even in position with some pot odds. The big blind's 3-bet range dominates this hand.

72 suited is the weakest holding and I am out of position postflop against the big blind; calling another 50 chips will not realize enough equity to be profitable.
