i went to the casino yesterday for the first time and i played blackjack. i had no idea what i was doing but i ended up winning some money! anyways, i know i was just really lucky yesterday so i figured i should learn what im actually doing before i go to a casino again. today i read over the rules about what doubling down is, splitting is, etc, and i memorized the three basic strategy charts. there's still something i don't understand though...is there a signal for doubling down or splitting? i know that you place your double down bet/splitting bet next to your original bet, but is there a hand signal to say you are doubling down or splitting? do you just put down the bet and the dealer knows you are doubling down or splitting? if you have a 5/5, does he just assume you are doubling down and not splitting when you place down the second bet? this is kind of a dumb question but i figured i might as well ask since i dont wanna look like a dumbass like i did yesterday....i didnt even know the hand motion for "stand"!
