Now online poker is more difficult and easier at the same time. On the one hand, it is more difficult to understand the strategy that opponents use, and to discover patterns. On the other hand, it is played with amateurs that is easier to win.
If you mean bluffing, then real poker player will not fall very often on that trick as long as there is strong base on the card statistics which they are analysing and practicing many times. I don't know what kind of strategy you are pertaining but being good on probability and statistics is the only strategy needed to win on poker. Bluffing is just an add-ons and will not gonna work against professional player.
The correct way of bluffing is very hard, sure we can just try to bluff with any two cars, but the risk of running into the nuts is very high like that. We need to block atleast some part of the nuts with our hand to have a plausible bluff. I agree that professional poker players rely heavily on statistics, so bluff against them is extra hard. Too many times a good poker player will just call you down with Ace or King high, because the chances that you both miss the flop, turn and river is quite high. On Youtube it seems so cool to watch the best off bluff compilations, but these are very rare hands. I think its better to just play the best hands and don't try to rely too much on bluffing.
