I'
m going to guess you have a
HUD:
check the
steal stat for your CO/Btn aggressor. If it isn't high
don't defend
light -you only need to defend when they're actually attacking (stealing)! his
fold-to-3-Bet-% is also very useful in telling you how to defend.
You also
don't actually need to defend as wide as you might think to get those percentages because the hands that reach the stealing point are the ones where lots of other people hold low cards ..leaving more high cards for you.
80% is something of a magic number as Btn can take the pot 2/3 uncontested if both blinds
fold 80% to his steals which makes them auto-profitable at 3BB (
well 64% is
close enough).
It's also probably not a huge
leak anyway whereas playing too many can be.
