1. They didn't travel all the way to the casino to fold.
2. Most decisions about the entire hand are made on the flop, so if your bluffing and get called on the flop strongly consider giving up.
3. A large portion will stack off with TPNK, they are never folding 2 pair or a straight. Per above if you have it jam the pot on the turn and river.
4. As someone said the game is much much bigger, standard raise is 5x-10x the BB and even those are usually multi way flops
5. Most players do not change gears, if they start out playing one way they almost always continue to play the same way.
6. Players value bet/raise on the river without much so blocking bets tend not to work.
7. When a player move it in, they usually have it.
