I figure there's no way to get away from this as he played it with my cowboys. Regardless, in this low of stakes (Party NL50) this call will pay off alot more than not. Just thought it was an interesting hand, certainly didn't expect him to turn over bullets. Maybe he put me (yet to act) on KK? [img]/images/graemlins/wink.gif[/img]
