i am not even happy w/ QQ going AI pre v villain w/ no read, but i am a dumb nit.

but that doeznt mean my blind 3bet range iz QQ+, AK, iz much wider then that and profitable like mozt people here.

yep, we can 3bet/fold if we have no info that v villain 4bet range we can profitable call or 5bet.
w/ JJ/TT + other blind 3bet range, money we make when he open/fold+ money we make when he open/call >>> money we loze when he open/4bet
