In Stud 8 4th street, my Queens (Q-Q-7) caught a 9 and my opponent (3 up) caught a 4. I act first: bet or check?

Heads-up, PokerToast's limit Stud 8 solver bets with Queens and 7-9 showing against 3-4, first to act 98% of the time.

The spot

The solver's numbers

The solver's answer
PlayHow often (strategy)Worth from here on (EV estimate, small bets)
Bet98.3%+1.00
Check1.7%+0.99

Measured on 2,312 play-outs of this situation. The highlighted row is the play that measured best.

Why, in plain words

Bet and check are worth about the same here (0.01 small bets apart, within the measuring noise of about 0.19), so neither is a real mistake; the solver's usual choice is to bet (98%).

What popular strategy articles say

Be cautious about putting in more money with a bare high pair and no low chance when the low draw is improving.

What strategy articles found by web search said on 2026-10-08 (PokerNews, Card Player, PokerStrategy, pokerskill and similar; mostly written between about 2007 and 2015, and mostly for full-ring games with several players in the pot).

Heads-up, the solver disagrees: it chooses the recommended play (check) only 2% of the time; its main play is bet (98%).

By the measured values, though, the two plays are worth about the same (within 0.01 small bets), so the common advice is not a real mistake here, just not the solver's usual choice.

Measured value from here on: bet +1.00 small bets, check +0.99.

Heads-up vs multiway

The numbers above are for heads-up play (two players). Most published advice is written for full-ring games with several players in the pot, so part of any difference can come from that.
