without cause or apparent design. I have already contended that poker is mathematically based and therefore we know why you made it as well as why you did not. It did not just happen; there was a skill involved. We all know that there is more skill than chance or luck in poker.
Thus my assertion, poker is not gambling.
I am sure that neither you, Blob, nor you Reptar, will accuse me of simply "using semantics" here, but mark my words;
someone will. They do every time. Lets see if I am right guys, lol.
And Rep, I have to say, merriam-webster should know better. They have let me down before; I have heard that the printed editions do not always match the online edition. I do not have one, so I do not know for sure. I always check definitions at several sites to back up my conclusions and form a logical consensus to arrive at the best definition taking all into account. What a pain, eh? And I have to do that in my job. It just sucks, lol. Damn lawyers.
