Bluffing, DN and IRL

Taking DN as the representative of virtual games, tag force, world championship (DS), YVD, YGO Pro, they're all pretty much the same, as long as your opponent is a real player and not a CPU.

The image says all about this technique

Bluffing, one of my favourite techniques in this game, how to use it (for newbies) and how to act against it (for pros and wannabe pros).
Bluffing is a techinque took from poker, that has been used in pretty much all the game cards, doubt could be a good example (for those who don't know, or call it with another name, the player discard a cards facedown, and says it is a 6, for example, another discards a card that should be a 7, but you can doubt of it, if the card isn't a 7, the one who discarded it will take all the cards discarded, if it is, the player who doubt-ed will take all the cards, instead).
In YGO, we'd use this technique to stop some opponent's moves, if he isn't a careless player, or we make him believe we have a poker hand (aka. awesome hand), limiting his moves. Let's say you have a mirror force set on the field, while the opponent has two stardusts and you have 2 cards in hand (random card and MST) and 4700 LPs.
Seeing it from the opponent's point of view, attacking shouldn't be a bad idea, in the worst of cases he'll drop a D-Prison or a Fader, but he can't go into gorz, since he still have a card on the field. If you were the player b that has double stardust, what would you do? You'd attack with the first, player A chains mirror force, and you negate with one of the stardusts, then you attack with the second for damages. At this point you won't think of nothing in his hand, it's a mind game, you won't think that he has gorz after he used mirror force, since gorz is limited at 1 it is less-probable for player A to draw into it. BUT, what if player A, during his turn, uses typhoon on his own mirror force? Wouldn't player B think that player A has a gorz in hand? Because if it isn't that move would be pointless, and since gorz here could have been game, too, you don't want that to happen, and you wait for something to respond to gorz.
That's one of extreme bluff, risking everything, since you would have gained only a turn activating that mirror force, surely that wouldn't have been enough (not surely, probably, depends from the other card you have in hand), while making your opponent think you have gorz, will have you gain tons and tons of turns, except if the opponent is lucky, lol.

However, extreme bluff is one of the rarest ones, everyday life consists mainly of ordinary bluff, such as "Player A sets a Dark Hole when the opponent has stardust on the field, making player B thinking he has D-Prison, instead." or "sets gold sarcophagus and D-Prison, if the player B MSTs one of the twos he'll always fall in player A's trap: MST on sarcophagus, he'll think both are bluffs, so he'll attack freely and get hit by prison; MST on prison, he'll think the other one is another protection trap and thus won't attack". Profit.
Bluff on DN usually consists of setting some of the less important cards first, since some tend to hit cards on the center with MST, or setting more and more cards when you have a bad hand to make him think you have a powerful backrow ready to exterminate everything.
The difference from IRL to DN bluffs are, mainly, that IRL you can help yourself with your body, some smiles, for example, can make your opponent think you drew what you needed. Bad situation, opponent has full field, you're at top deck, draw gold sarcophagus, smile as you're limitating yourself from laughing hard, set gs and end turn. What would you think if you were the opponent? Of course, player B (the one with full field) could be careless or having an MST/Heavy Storm, but doesn't matter, you have a chance of winning like this.

When you're in one of this situations, where you see the opponent doing something like what we saw up here (setting GS, but thinking it is mirror force), what could be the best response? Put some monsters in defense is, usually, the best thing to do, and then attack. Even if it'll need two turns to kill the opponent, three if he uses that mirror force (that is a gs, so that won't ever happen, but you don't know that) on the second turn of attacks, but with that few draws he has, they won't be enough, except for DH, lol.
Against the two set cards, I'd play it differently, I'd set my MST and end turn, killing only one of the two cards isn't enough, so I'd prefer waiting for the second MST or heavy, and use this mst as mst bait (maybe one of the two set card is mst itsellf) or using it to negate some power plays with Dragon Ravine/DW Gate/Necrovalley+big beater/call of the haunted, etc...
Against Gorz, no way, continue attacking freely, if he MSTs his mirror force. See it from the opponent's point of view, if he really had gorz, what would be the point into MSTing his own mirror force? He could simply have used mirror force on one attack and drop gorz on the second one, mantaining that MST for future uses.

Sorry for the kinda fast post, hope it was useful, however, but on this argument there weren't lots of things to talk about. I did this because I fell in love with that image mainly, lol.
Well, See Ya.
