Thanks all,
Karl played a different game to what I wudda expected. He was as tight as anyone I"ve seen, until the antes started when he rasied and won the 1st 2 pots uncontested. I guess he was totally card dead for most of the night (only hand he showed was AA which generated respect for any raise).
Anyway, he had got low stacked with 6 left when he raised for 5 x bb leaving only 200 behind. I noticed he hid the few remaining chips behind his hands. Was a strange exit. He was called preflop (after the caller & eventual winner asked how many he had behind). The flop was of course academic, the remainder went in and d his Q3c lost confortably to AA ?? Guess the caller wanted extra action.
