In my experience, when you see these things happening in a section of hands in a baccarat shoe, that's the time you will have a really, really bad losing section of the shoe ( lose 9 of 10, lose 6 in a row, lose 7 in a row etc etc ) or get killed in the entire shoe :
1.You lose to a natural ( you bet Player and banker wins with a natural )
2. You lose on a 7 to 6 ( You bet Player and lose to Banker 7 to Player 6 on the first 4 cards )
3. You are behind on the first 4 cards and lose the hand ( you bet Player hand have a 1 on first 2 cards and Banker has a 3 on first 2 cards so you are behind 3 to 1 and Player draws a 10 for total of 1 and Banker draws a 3 for total of 6 and you lose ( Whoever is ahead on first 4 cards wins between 85% and 95% of the hands since other side has to "catch up" ...if you are constantly behind on the first 4 cards, you will lose most of those hands )
4. You are ahead on first 4 cards and lose the hand......you bet banker and banker has a 3 on the first 4 cards and Player has a 2 so you are ahead, 3 to 2 but Player draws a 7 for a total of 9 and Banker draws a 2 for total of 5 and you lose. You are "supposed" to win but lose instead.
This is not a "system" (unless someone is smart enough to develop one) but if you see these situations appearing in a section of the shoe, you are most likely in for a beating.
The opposite is also true for a good section of the shoe...............but the bad sections will be more than the good sections since you are playing a negative expectation game and will lose more hands than you will win.
