thanks for sharing very useful10% sounds very high for a heads-up format, but it also depends on the speed and starting stack. If they give you 100BB and 10 min blind intervals, then its probably beatable at least in the micros. But if its 25BB and 3 minute blind intervals, its almost certainly not beatable. On PokerStars the heads-up SnGs are now all hyperturbos, and the rake is 6% for $2 and $5 games, 5% for $10 games and 4% for $25 games and above.
