That crazy graph

The steep red line on my crazy graph represents money lost by a fellow donkey at micro stakes nlhe SNGs over 2500 games.  I faced this particularly erratic aggrodonk on one occasion and was curious to know the long term profitability of his strategy. Having sharkscoped the poor chappie's results I was taken aback and it gave me serious food for thought. Here is a poker player with close to a grand to spare (assuming this is his first deposit) who has played and played and played and not got any better at the game. Forget variance, forget suck outs, this is a clear case of not knowing how to play poker and making no quantifiable impovement whatsoever, over a relatively small but nonetheless financially significant sample size.  I began google searching for crazy sharkscope graphs and found a genius thread on two plus two forums full of them. Some players, sponsored pros even, absolutely stink at poker and will gladly reload, rebuy, redeposit and spew their cash into the poker economy. I am determined that in the long term I will maintain the wherewithall to avoid this kind of long term negative result.  I have had harsh words with the gambler in me and sent him packing, off to waste his money on something frivolous.  It is possible to play poker for 'fun' or 'the buzz' but its so much more of a buzz to remain in control and make good decisions that lead to success.
