I don't think we'll agree on this one as I think 'bad' is subjective. So, I can cope with 'I find her a bad player', or 'I find her a frustrating player'; but not 'she is (objectively) bad.' (or absolutely terrible.) as in, I think it, therefore it is.

There may be learning problems, dyslexia, a totally different motivation to you for playing the game which make her, in her mind, wonderful; and winning, having lots of long and interesting words, whatever, may not be her motivation!

But, I'll agree to differ! And I hope your next few moves with her enable you to get enjoyment out of the game.
