Yet another scrabble dispute.
I'll get straight to the point.
I had two letters that I wanted to use, namely "B" and "F".
There was the word ET on the board and I simultaneously added B right before the ET and F underneath my B, thus forming two words (BET horizontal and BF vertical).
My opponent claims this is against the rules and I can only add the B for BET.
Who's in the right?
