I'm with rilla and put all the blame on zook.. My assumption is that he found out we were on to him and therefore he straightened up for the time being in an attempt to gain our trust and further infiltrate FTR. And once in he can continue his quest to change poker rules in favor of 2 pair over trips. In fact, I am now reminded of a time during our coaching session in which he said "Boy I sure wish I had 2 pair here instead of this lousy set!!!". That sure sounds pretty shifty to me sir.
