when i see 53s or 42s, i'm praying for a deep stack to raise with aces..
Really? Just roughly...

With 2 suited cards, you'll flop a flush 1 every 119 times.
You'll flop a straight 1 every 102 times.
You'll flop a full house 1 every 1088 times

These events aren't completely independent of each other and a few other things might happen... you might flop trips and have the best hand, you might flop trips and have the worse hand, you might have the lower end of the flush, you might get outdrawn and lose...

Let's just say you are successful 1 in every 80 times.

Let's assume on average that it costs you 3.5bb every time you call this raise. Also, let's assume you're both deep stacked at 200bb each.
So, you win 200bb once and lose 3.5bb 79 times.

Net profit: 200 - (79*3.5) = -76.5bb.

This is all very rough. But i'll put it another way.

If you're both deep stacked at 200bb, and it costs you 3.5bb on average per call, then you HAVE to be successful at least 1 every 58 times.

If you're only 100bb deep (as is common), you have to be successful at least 1 in every 29.5 times.

I am pretty sure Super System is all about bullying players. 42s will flop a fair number of draws, in which case you at least have SOME equity if the better hand calls you (even then you don't want a call from AA).
