What is every hand worth on a 2 4 7 rainbow flop?

On a 2 4 7 rainbow flop, any pocket pair that connects with or sits above this board is a big favorite against a random hand, every flopped set is close to a lock, and even a weak pair like Q4 offsuit runs well ahead of a coin flip.

Notable hands on 2 4 7 rainbow

Hand	Flops	Equity	Why it matters
77	set	95.3%	Top set. The best possible hand on this flop, and there are almost no cards to fear.
AA	overpair	86.4%	The classic overpair. Nothing on this board threatens it yet.
Q4o	pair	64.9%	Middle pair with trash kickers, and still well ahead of a random hand. Dry boards are kind to any pair.
22	set	94.0%	Bottom set. Tiny preflop, monster here.
A7s	pair	77.4%	Top pair top kicker on this texture, a comfortable favorite.
AKo	nothing yet	53.2%	Completely missed. Still ahead of a random hand on high cards alone, but it gained nothing from this flop.
65s	nothing yet	45.6%	An open-ended straight draw around the 4 and the 7, one of the few live draws this board offers.
53s	nothing yet	43.2%	Another open-ended straight draw, this one needing a 6 or an ace. Sneaky equity for a hand this weak.
KQo	nothing yet	45.5%	Two overcards, no pair, no draw. This is what missing looks like.
32s	pair	55.6%	Bottom pair with the worst kicker. Even this beats a fair chunk of random hands here.

The 2 4 7 rainbow flop is about as dry as poker gets. There is no flush draw, no open-ended straight draw using two connected big cards, and no way for a random hand to have flopped a straight. That scarcity of draws is exactly why made hands hold their value so well here: when you are ahead on this flop, very few turn and river cards change that.

Overpairs are the big winners. Pocket aces, kings, queens, and even eights are miles in front of a random hand, because the board offers so little help to the hands behind them. The three flopped sets are near locks, and the only real danger they face is the runner-runner straight or backdoor flush that a random hand rarely gets there with.

The trap on this texture is the middling unpaired stuff. Two broadway cards like KQ or AJ have completely missed, and whatever value they keep comes purely from unimproved high-card strength. KQ actually falls behind a random hand here, and AJ scrapes barely ahead, a long fall from where both stood before the flop.

The common mistake here is over-folding small pairs and under-folding big cards. A hand as ugly as Q4 offsuit has flopped middle pair on this board and beats a random hand comfortably, while good-looking hands like AK gain almost nothing from this flop. On dry low boards, pairs are king and paint is a promise.
