Things I learned from club this week

1. Missed ACMOTTU to an H. Also forgot MAUT.
2. RURBAN is a cool word.
3. EINRRY? plays through an A.
4. CEEKNT? has one anagram.
5. OK, here's the big lesson: I lost the second game three times. Here's how:
    a) I had AEGNORS and thought S(MUTCH) was good but didn't know for sure.
    b) I didn't take long enough to find the one spot my opponent could play his Q for a bunch of points.
    c) I didn't find BREN as an outplay, the only one that would've won.
Had I done a, b, or c I would've won the game. Here's the question I have for you more experienced players:
So I held MUTCH when it was played, but luckily let it stay. Here's the board. So what should I have done? I had a slight suspicion that SMUTCH was good. But if I play my bingo and I'm wrong, I likely lose. I obviously end up blowing the game anyways, but can anyone come up with a strategic way to decide whether not to make the play?
