Winning in Tough Hold'em Games
by Nick Grudzien

Though many books cover Texas hold'em, few concentrate on the tougher aspects of short-handed hold'em, particularly in the high-stakes limit hold'em games often found in the online poker arena. Both authors, who were fraternity brothers, gained most of their needed experience online. The authors start with a detailed explaination of the typical players at various limits, starting at the $3-6 level and progressing to the $150-300 and up limits. Their work is peppered with charts that verify the concepts and theories they teach and include pre-flop play (opening with a raise, playing to steal, isolating players, restealing, limping, etc.), defending the blinds (three bets, four bets, handling passive and aggressive blinds), post-flop heads-up play (responding to check raises on the flop and turn, betting the river as a stone bluff, turn value check, the semi-bluff, and more) plus miscellaneous topics. The final sections include sample hands and discussions of them, quizzes and a summary.
