I've won two SNGs today. One was a $1 + 10 and the other a $2 + 20. I'm still finding it difficult to quickly workout odds, outs and pot odds but I am learning to get a read on the players at a table. I believe I used this to maximum advantage in these two games and watched what the other players were doing. I play quite aggressive and was able to bully those I perceived as weak off the hand a lot of the time. 
I've also managed to tighten up my starting play, loosen off a bit in the middle and then go super aggressive in the money. (All learnt from PSO Online and so far it seems to be working). Anyway, my account is showing it's first profit so I couldn't be happier.
