Bread-Bakers v102.n009.8

I have been using the King Arthur sourdough starter for a few weeks and am 
very pleased with the results. However, I simply cannot achieve the "chewy" 
texture that I love in artisan breads. I have tried the biga technique and 
now the sourdough, but the crumb I seek remains elusive. If you know how to 
achieve a chewy texture, please let me know.
