Few dealers will cheat ....
Cheating was not uncommon in the "Wild West" in the past, so why not in the "Wild East" nowadays.
Few dealers will cheat you in US, may be because there are quite a few expirienced gamblers to detect it.
Here in Russia it it different. Here it is possible, that some business man is killed in an armoured Mercedes using a thermite shell, designed to crack a NATO tank.
So, still convinced about minimal amount of cheating in Russia ?
In case, you are brave, there are very fashionable casinos in Moscow and St. Petersburg, one is looking like ancient palace from the inside (better than Monte Carlo), offering also alcoholic drinks like whiskey (here whiskey costs a small fortune, because of import) or sandwiches with red caviar for free. And there is quite some choice in casinos of different levels. I have the impression, besides Vegas St. Peterburg and Moscow are among the the biggest gambling cities in the world, regarding number of casinos.
So give it a try here, it is even very pleasant for day time leisure activities. Being a german, living in Russia, I prefere St. Petersburg much more than Moscow. Much more culture here.
