Just like in ‘bridge’ (a card game), in scrabble we could sometimes have a trump card. And as with any other trumps, we just need to play it right. Now what are you going to do, if you have a rack and a board like this?
Holding the last Y, I made M10: PUNCH. Then my last Y became a trump card since it was the only letter that could ‘back-hook’ punch (PUNCHY)—reaching the upper or lower TWS. There was still one wildcard (blank) somewhere (either in the bag or already on Blue’s rack), but this was worth the risk (and it just so happened that my next move was 15L: DYNE).
Sowpods word: DA, GERT
