You got unlucky in an insignificant hand. If you had been playing with someone other than Sklansky heads up, would this hand have seemed so important to you?

Let me take a guess that DS is checking the river to induce a bluff, since he assumes you probably dont have much. Since you bet the flop, checked the turn, and bet the river DS put you on a hand that either "improved on the river" or a bluff trying to pick up the pot. Since the river card could make a better two pair and two straights, he opted not to raise. If you have a bluff you obviously wont call, and if you are lucky enough to have one of the other hands, you almost definately reraise. The odds of a raise being called isnt high enough to taking a chance of being reraised when a reraise will almost always be a better hand.

Thats my feeling about it... Yeah I know I'm a moron and have no clue...whatever.
