JohnCover I had one similar to this. It was about a year and half ago and I still remember it like it was yesterday since it was my biggest loss on one hand by far. I had split to two hands with my max bet, which was $80 on two hands and the dealer pulled up a 6. I was feeling good at this point. Both my hands were pairs. I don't remember now what they were but neither one was two 10s. I never split 10s. On both hands I proceeded to spit them about 3 or 4 times and had at least 3 or 4 doubles on those hands. I had to go into my wallet at least 3x, and it might have been 4. All I know is I had a lot of money out there. Everybody was rooting for me, even the pitt boss came over and was rooting for me. The dealer had a hard time making room for all the hands due to all the splits and doubles. The pit boss, dealer and the table genuinely wanted me to win that one.
To my shock (and everybody at the table, including the dealer and pit boss), the dealer turned over a five for a 11. I still can't believe that happened because the count must have been like a TC 6 to 8. I don't need to tell you the rest of the story. The dealer pulled a 10 for 21 and took all my bets. And I had several 20 and 19s on the table. Needless to say, this one hand pretty much killed my whole weekend.
It's been a year and a half and I'm still trying to recover from that hand, more on an emotional level than a financial level. Lol. It didn't hurt me finiacial but I still find it amazing that the most money I've ever had on the table and the dealer draws to 21.
This story probably doesn't help your situation but I wanted you to understand that these kind of things happen when you play blackjack.
