if condition for different terms

Hi all,
I'd like to put an IF statement into the node block for useing other block templates based on if the node has some terms in the taxonomy but I cannot get it working.
Here my temtative:

<div class="node<?php if ($sticky) { print " sticky"; } ?><?php if (!$status) { print " node-unpublished"; } ?>">
  <?php print $picture ?>
  <?php if ($page == 0): ?>
    <h1 class="title"><a href="<?php print $node_url ?>"><?php print $title ?></a></h1>
  <?php endif; ?>
    <span class="submitted"><?php print $submitted ?></span>
    <?php if (( (( $block->module == 'block' && $block->delta == 3 ) || ( $block->module == 'node' && $block->delta == '0' )) AND ($taxonomy->term == '14' ) )): ?><span class="taxonomy"><?php print $terms ?></span><?php endif; ?>
    <div class="content"><?php print $content ?></div>
    <?php if ($links): ?>
    <div class="links">&raquo; <?php print $links ?></div>
    <?php endif; ?>
</div>

the line is
<?php if (( (( $block->module == 'block' && $block->delta == 3 ) || ( $block->module == 'node' && $block->delta == '0' )) AND ($taxonomy->term == '14' ) )): ?>

what I can get it's just to change template for all node if I use in anyone the term "14"

my gola insead is to select just the node that have such term

some suggestions?

thanks a lot
