A blunder is a grave mistake. In sports or in games, it usually refers to an action or a decision that turns a foreseeable win into an irrecoverable loss.
There are things in scrabble—however legal, that we’d rather not do. Here are two of them, both involving giving the opponent unnecessary scoring boost.
Red had just moved 8K: LUAU. This is reckless. Giving a TWS to your opponent like this is a big—and I mean Big, no-no. Just check out what Blue had got on the rack. With O4: ZETAS, Blue would kick an easy 87 pointer. Without throwing a blank, and it’s not even a bingo(!).
