Not Tight, Just Card Dead

By the time we arrived at Mike Matusow's table there was a {4-Hearts} {3-Diamonds} {10-Diamonds} flop out on the felt and Matusow was in the small blind position against one opponent in the cutoff. Matusow checked here and then called the bet of 1,250 from his opponent. Both players proceeded to check down the {4-Clubs} turn and the {8-Clubs} river and it was on to showdown.
