Hold'em table

J♠9♣ is a reasonable button open in a three-player game. Raise to 250 to apply pressure while keeping the pot manageable.

Queen-four offsuit is far too weak to defend the small blind against a 2.5x raise, out of position with a dominated kicker. Folding is clearly the best play.

63o is far too weak to defend out of position against a 2.5bb open, making folding the standard play.

Ace-nine suited-ish offsuit on the button in 3-handed play is a standard open; I'll raise for position and fold equity.

73o is extremely weak and an easy fold from the small blind facing an open raise.

6♦4♥ is a weak offsuit hand and the 3x raise leaves me out of position with little postflop playability. Fold rather than call 200 chips.

J4o is too weak of an offsuit hand to open profitably from the button even in 3-handed play.

With the button folded, completing costs only 50 into a 150-chip pot, and T5 offsuit has enough equity heads-up at this price.

I'm in the big blind with 6-high and there's no bet to call, so checking is free and lets me see a cheap flop heads-up against the limper.

With only ten-high and no meaningful draw on a paired flop, betting has little value; I’ll take the free card.

I flopped two pair (jacks and sixes) and seat_1 checked, so I bet for value while charging draws. A modest bet keeps weaker jacks or flush draws in the pot.

I have no pair or meaningful draw on a paired board and would need to call a substantial bet with very little equity.

2-4 offsuit is too weak to play, even on the button; fold rather than invest 100 chips facing the big blind.

Calling 50 into a 150 pot heads-up against the big blind requires only ~25% equity, and J9o has far more than that against any BB defending range. Cheap flop see with a playable hand beats folding or bloating the pot out of position with a marginal raise.

I have 87o in the big blind facing an SB limp; checking allows me to realize equity in position for free.

We have second pair with a mediocre kicker in position in a limped pot. Checking behind controls the pot size and realizes equity nicely.

I hold only J-high with a weak one-card flush draw and no real straight draw; with the flop checked through and no fold equity established, taking a free river is best.

I have middle pair with an eight kicker on a board with several draws; checking behind controls the pot size and realizes showdown value.

My J-high missed the board entirely; checking back the river avoids putting money in with little fold equity against a passive BB.

I have two pair, Queens and Sevens, with decent showdown value in a limped pot that has checked all the way down. Checking behind secures showdown without risk of running into a better hand or check-raise.

T5o is too weak to complete or raise from the small blind out of position against the big blind.

J5o is too weak to open even from the button in 3-handed play.

With the button folded, A4 offsuit is a reasonable heads-up small-blind raise. A raise to 300 applies pressure while keeping the sizing modest.

96o is a weak hand facing a 3x raise out of position; folding is clearly best.
