Ken's the man
I've had the opportunity to play against Ken in BJ tournaments. If anyone doubts Ken's abilities I suggest they get a subscription to All In magazine and read Ken's column, Tournament Zone.
There are many aspects to BJ, especially when playing against the house, AP or team play. Now try doing that in a BJT and it's a whole NEW ballgame. Why because you not only have the strategic play but the betting strategy.
On an aside while playing at a casino north of the border I overheard a pit lady make a comment to the dealer & player at the table which I was playing. It was something along these lines, "Yeah that's Ken Smith back there. He's probably one of the top 10 card counters in the world. He can count down a deck in around 20 seconds." (HER words, not mine).
PS Ken was unaware of her comments as he was talking to fellow BJ players. Ken definately had HERE respect, as he has mine too!
But how do you measure "best"?
Most money won/least money lost?
Longest amount of playing time?
Best resume/credentials/etc...
How about someone who gives back to the BJ community and is willing to help others? Does that count?
Ambassador status?
If you really wanted an answer, which I don't think you do, sponsor a heads up best 2 of 3 BJT between LVHCM and Zen and Ken. Do it round robin style, 30 hands and use a single deck.
Or another method is to have all 3 players given 2,000 in chips. Play against the house, 1 or 2 shoes, no max bets. Most chips at the end of two shoes is the winner.
