you might try slapping a vowel next to a triple letter square while leaving something somewhere else to entice your opponrnt to play there... go for a 2-letter word like ZA XI JO QI.... now, if you really want to score points, leave a CONSTANaNT (possibly a vowel depending if you can make OE AE OI, etc)... the object would be to then make TWO two-letter words at once getting you 6x the value of the tile..... this even works good with tiles like M, P, B and F.... which would get your 24 points a pop for just that tile alone.... cheers (the S's aren't even needed)
i got 37 points for the word "IF" against my aunt.... F on a triple letter square... made the words IF twice and the word QI (played IF directly under QI)
