If Grant's performance was less than impressive, what does that say of Lee ?
IMHO Grant was a methodical gambler who maintained the " House Edge" even at times without supply lines. He played the table and recognized it's odds.
By contrast Lee was splitting face cards and at times doubling down on them. When he was lucky he was declared "brilliant" and when he lost it was because of a lost cause.
"it was the dealer, no pushes, they changed the dealer, too many decks in the shoe, blah blah blah"
If Lee was seated next to me at a blackjack table i would probably get peeved and change tables, after a few choice expletives.
