My local casino has given me a bunch of 2 for 1 blackjack coupons because I play so much poker there. I've received 6 coupons in total so far.

The max bet is $500 per hand, but I was curious with my 1.8% edge, what is the chance of a huge swings? Mainly, what's the chance at a $10,000 loss, $20,000 loss, and $30,000 loss. Since blackjacks occur roughly 1 in 21 hands, I'm going to play around 126 hands. Any help would be appreciated.
