Double Attack & Spanish 21

After laying off several years, I have decided to play BJ in AC again only to find several new BJ games including Double Attack and Spanish 21. Are any of these games beatable?

Spanish 21 -- is ordinarily a "Carnival Game" -- BUT if one studies the fine work of Katarina Walker as published: "Pros Guide to Spanish 21" If you are willing to learn a rather complicated Basic Strategy you will find a game with an .e.v. similar to the regular BJ games available in A.C. but with very little, if any, chance of having the casino take counter-measures against you. The drawback is that you will need to spread your bets pretty wide and that always translates into a high Risk-of-Ruin that will require the player to be armed with a rather large bankroll - 500 units will be risky. I suggest at least 1,000 units. With that said, everyone's level of Risk Aversion is different.

Double Attack Blackjack:

I strongly suggest that you learn to look up games at a great reference site:

Double Attack Blackjack is a blackjack variant with lots of rule twists. The most interesting is that the player may double his bet after the dealer�s up card is dealt, before any player cards are. The game is popular in Atlantic City, where it can be found in about half the casinos.

Rules:

Eight 48-card "Spanish" decks are used. A Spanish deck consists of the conventional 52 cards, less the four tens.
Dealer stands on soft 17.
Dealer shall peek for blackjack.
Player may double after a split.
Aces may not be resplit, all other pairs may be resplit to 3 or 4 hands, depending on the specific casino. The analysis that follows is based on resplitting to four hands.
Winning player blackjack pays even money.
Player may double or surrender at any time, including after splitting. Any one hand may be doubled only once (no redoubling). Surrender after splitting is done on a hand-by-hand basis.
Split aces receive one card only.
Insurance pays 5 to 2.
The first card dealt is the dealer�s up card. Immediately after this card is dealt, the player has the option to �Double Attack,� by raising his bet. The raise may be up to the original wager. If the player later splits, he must match his Double Attack Bet, if he made one. If the player doubles, he may do so up to the sum of the original wager and Double Attack bet. If the player surrenders, he will be refunded half his original and Double Attack bet.
An optional �BustIt� side bet is also available. The �BustIt� bet pays if the dealer busts with exactly three cards. Otherwise, the �BustIt� bet shall lose. Most wins will pay based only on the dealer�s third �bust� card, as follows. There is a premium win if the dealer�s three cards are all eights.

FOOTNOTE: I have seen this dealt (not recently) at Caesars A.C. as a PITCH GAME with 50% penetration. It was interesting for me to watch as a "spectator sport".

Hello Marty or Flash:

When they are using 8 decks,where do they usually place the cut card?
