So most people have told you the same thing. Full house Sevens over Queens.
So this teaches us something important...
Whenever there is a pair on the board, you are at risk of being beaten by a full house, either by holding pocket pair which matches one of the other, non-paired community cards, or by tripping with one hole card and pairing with the other.
Now, ignoring the full house for a moment, this also (sort of) highlights the difference in strength between "Trips" and a "Set".
The former is when one of your cards matches up with paired board cards.
The latter is when a pocket pair (hole cards) match up with a single community card.
A set is much more hidden. The board can sometimes look relatively innocuous, yet your opponent can be on their way to a monster hand.
In this case, the set was so well hidden that it became a boat, and that was missed.
Now, I'm not telling you to run with your tail between your legs whenever the board pairs with itself, but you do need to take it into consideration when betting, calling or raising.
On the other hand, when the board pairs up, it may also be an opportunity for a
bluff, scaring your opponent off, knowing you might have trips or even a boat. Depending on who you are up against, their skill level, and hand history, you can use this to your advantage (some portion of the time).
By the way, no need to feel foolish when you miss something that is obvious to others. We all do it from time to time. I sometimes used to miss flush draws when playing on my phone, because it was so hard to differentiate hearts from diamonds and spaded from clubs. (Hint: Using a four-colour deck helps solve this issue). Similarly, it can be easy to miss gapped straight draws if you're mind isn't fully on the game, or you're playing fast paced games or if you are p0laying many games at once.
Heck, Spraggy managed to be holding AA and let his clock time out yesterday because he was playing a number of tables simultaneously.
Don't worry about the mistakes. We all make them. And don't pay attention to anyone here who tries to make you feel foolish about it. Just identify the mistakes you make, and work on a strategy to avoid them.
