Am I understanding the KO book correctly in thinking that in a 2D game, for 12v4, 12v5, 12v6, 13v2 and 13v3, you stand if the RC is equal to or greater than the IRC (as in BS), but HIT if the count is less? In reKO, only the 12v4 is listed as an index play for 2D but +2 is used. The others are included for SD, but also at +2. That doesn't seem to correspond to how the rest of reKO compares to Preferred KO in that +2 is well above the IRC. Or am I misunderstanding something?
Also, if I am correct in my understanding of the index play calling for a hit on pretty basic plays that are contrary to BS, and grouped around 12 and 13 against low dealer upcards, is that likely to be recognized as an index play by alert dealers or PB's, or do more people take a hit on those plays than I would expect?
