It would be interesting to do a computer simulation to see how big that bankroll would need to be.
I went to Reno in 1981 as a nerdy 27-yr old and the plan was to play blackjack.
I had studied the game somewhat and was pretty c̶o̶n̶f̶i̶d̶e̶n̶t̶ cocky.
The strategy I planned to use was "If you lose, double your bet".[1]
There are two catches — first, there is a maximum limit on the table. If you're starting a $2, the most you can bet is $200
If you lose 7 times in succession, your required bet is above the limit on the 8th hand.
Secondly, we only had $1200 with us,[2] so even if we lost 6 in a row, it would have eaten up almost half our available money.
Third — (I can't count) — if after a string of 5 losses, you win on the 6th hand, you have risked $64 to win two.
Too make a long story short (too late
) at one point I had lost 4 in a row and was a bundle of nerves as I played the 5th hand. I won it, but I stopped playing that way.
Some time later I ran a computer simulation to see just how often a player would lose playing this way. I can't remember actual numbers, but it was a lot.
[1] This strategy is called "Martingale"
[2] That was all the money my wife and I had at the time.
