HIOPT II index for 99 v A is TC +6. HIOPT II is a level 2 count.
If we are talking hands and not the hand that was most enjoyable, I like blackjack. For the other, I was playing where you could split and unlimited number of times. I split eights to a total of 11 bets (some were double down bets). Only one hand was not a made hand and the dealer busted his stiff. I had all the money I had on me on the table and won every bet.
