Lol jinnia!
Well I watched rainman or bakelady, whichever he/she is for at least an hour starting about 10 mins after his/her post. He/she was playing alone versus the dealer.
What I observed was a remarkable number of player blackjacks, probably twice as many as the dealer. The dealer ALWAYS checked for bj when he had a 10 showing or an ace showing after offering insurance. The player did not play perfect strategy as previously stated. I had a chart open on a second screen while watching the game and during that hour observed at least 5 deviations from perfect play strategies (e.g. splitting when you should hit, or vice/versa, doubling/not doubling when you should/shouldn't, etc). At least 4 of these were costly errors, resulting in a loss/push/or smaller win than the player should have had.
But the main problem I saw was the utilization of a progressive betting 'strategy'. I think all of the experts agree that these are doomed to failure. This accounted for the largest percentage of player losses. Also, the player didn't drop back to their original base bet ($4) after a while and began betting more and more in an apparent effort to win back losses. This is also a strategy that is doomed to failure. The player was staying pretty much even until these strategies began taking their toll. After about an hour on this low limit table, this player lost about $200 and was still playing when I left.
Looked like a typical land based game to me. I didn't see any obvious cheating by the dealer. I'd say both player & dealer got their share of multicard 21 hands, and as I said before the player had probably 2x the number of natural bj's as the dealer. Chasing lost money and getting greedy on some hand is coming back to bite him/her. The problem is really with the way the player is betting & playing, not with the RNG.
