I ran a pio sim for MP vs BB on Ad4s4c rainbow. My question is why does 109dd has lower equity than other 109 suited combos. I have given all the A9
and A10 combos to BB. So in terms of blocking value all the 109 are the same. But since BB has all the Ax of spades and clubs, there is high probability of BB backdooring a higher flush when we backdoor a flush. So shouldn't it be the opposite ?
