Will a 1-2 spread keep me under the radar?

I only started learning to count in some semblance about a month ago, before anyone says "don't even try" I know that I wouldn't be able to pull off any significant player advantage at this stage. I would only really feel comfortable sitting down and playing blackjack, while counting but not really doing anything a normal counter would do... such as having a 1-4 spread. Call it practice.

Let's say I get to a true count of +10 and want to play it a bit, would doubling my bet from $5 > $10 or $10 > $20 set off any red flags? Has anyone has experience doing this? Thanks~

Absolutely not will you get any heat.

It will probably keep you under the radar, but I don't think you could get to a positive player advantage with such a small spread.

You should be perfectly okay with a 1-2 spread. That will cut down the house edge by about 0.25% only, but better than basic strategy. In some situations a conservative spread is the right thing to do. For example, you have to play a lot of hours for a "free" promotion you are doing, like a tournament.

Alright thanks guys, I'm trying to find a HA around that .25% already so all I really have been wanting to do is break even.

You'll want a double-deck game where the dealer stands on soft 17, and double after split is allowed. The nice MGM-Mirage properties have those rules, as well as the Treasure Island. Just check Vegas blackjack survey.

Under the radar, and under water unless you are wonging. Your spread must be higher. And a true count of +10 is very rare. You need your max bet out at +4 or +5.

Counting cards is a boring grind, especially since the casinos tightened up the game. Go to Casino Royale and max out the odds behind your pass or don't pass bet. Have a free drink and some fun (which counting cards is not).
