Would you split 10's at a TC+4?
I mean if dealer face up cards shows 2-9 sounds like a good bet huh?
Haven't seen an index play for this, good idea?
In theory sure, but it often attracts unwanted attention, i.e. pit crew etc. and perhaps more from the other players. I personally don't do it unless I'm just about to leave some worthless club i.e. Harrah's, Cal-Neva.
There's an easy "Rule of 10" for splitting tens. Just subtract upcard value from "10" and that's your index for splitting. E.g. Dealer shows
4, your index to split is +
6;dealer
5, index +
5; dealer
6, index +
4. Simple as that!
