Recently, found myself with 2 x multi-black-chip bet, had A9 and TT. When it came to me, RC was +15 hi/lo with 0.75 decks left. In an uncharacteristic fit of restraint, I waved them both.
I was discussing this with a friend, he estimated +100% advantage on the ten split (assuming I would in fact double soft 21) and +70% on the A9 soft double. I think he may have chafed his rectum pulling those numbers out, but I'm curious how close he actually was. Anyone?
