Reversing withdrawls has IMHO always been the psychological "edge" that the casinos have over the players. At some point virtually any win will turn into a loss (as the house wins overall anyhow) so by reversing a withdrawl you are just continuing to play for longer and playing into the hands of the house.
Many times I have reversed a withdrawl and lost it all (and more) - and many times I have had the patience to let it go through, stop playing at that casino for around a week - and wait for the money to arrives.
My method at the moment is to "bank" at least 50% - but usually 75% of a big win and continue to play with the rest, repeating the procedure when the next win comes up. This often ends up with having a few "pending withdrawls" concurrently -usually with one big one being the first withdrawl followed by withdrawls in various sizes. I continue to play with my "excess winnings" and have a rule NEVER to ask to reverse more than one withdrawl in the queue.
So i might have withdrawls for EUR 1000, 500, 750, 500 and so on and say EUR 200 in play money. Should the 200 be spent I allow myself to reverse ONE withdrawl - in this example the 500 - but everything prior to that is sacred and not touchable. As I continue, time ticks on, and suddenly the first withdrawl has been paid out by the casino anyhow.
This method - which of course requires self-discipline - has worked for me on several occasions
Hope nobody minds me sharing a bit of strategy on my first post here ...
All the best and good luck to everyone .
