Single Deck straight up strategy. I'm still working out the details on doubling 10,11,vs3,4,5,6, hitting 16v10 and 12v4,13v2,3,4 14vs2,3.
I can't present on argument against Ralph Strickers style of setting the bar high on 12v4 an 13v2,3 and always standing on 13v4,14v2,3.

It's costly to Always stand on 16v10 as some say is a prudent move. Hitting at -1.5 equates to always standing on the first hand.

The idea of doubling in a high negative count has never appealed to me. I read somewhere the dealer bust rate with 5 or 6 up around 42% of the time. This indicates to me he doesn't bust 58% of the time. I would think that number would increase as the count decreases. So, in a negative count, I'm doubling my investment to likley receive a small card and then hope the dealer busts which is less likely since they only have to reach 17. I've got to get a 6 with 11 or 7 with 10 to reach 17. What is wrong with this picture?

The four game changing stages in a percentage count are 50%, 57.14%, 60%, 66.67%. So an RC -3 (43% to 47% range) make cover it all. I have to do some research first. I find it odd that we hit 16 wanting/expecting a small card - yet double on 10,11 wanting/expecting a large card. It seems the happy medium is around RC -3 (43% to 47% range).

Under a similar notion, I double v 9,10,A with the count used for insurance decision at 57.14 to 60% high cards remaining. We think there is a 10 in the hole vs A when we insure. We hope to get a 10 when we double. Except on 10 vs 10,A as it really comes down to how many Aces remain.

This serves as notes to myself before I begin research. I appreciate/value your input.
