recently everytiime i hold kings or queens then an ace comes in the flop, it looks like is rigged, the last three days has been like amost everytime (i started to gt my own stats about the
hands with more impact in my stack) and yes 12 times i got kings and in 8 an ace appeared in the flop, which is way over of expected, and starting with higher pair than my opponent i have lost 15 times out 32 going allin preflop (again out of proportion), yes i´ve won a bunch of hands in the same period beginning way behind and getting a set or two pairs or any other better hand, but i don´t know if this is only a streak or is always like this (not only with me but i follow the game when others shove and it looks that the same story is going to happen, i mean so many hands like 7-7 against J-J, A-J against K-K, KQ vs QQ and so many times the former beating the latter, i know they have a chance to win, like 20%, but still it means one out of five 5 and it looks like the other way around)
now, my point here is that everytime an ace gets in the flop, then your chances to beat any villain are diminished (no matter if the villain doesn´t hold an ace because you have to slow your pace because the chance to be behind are higher), the ace gives the chance to your opponent to complete a set, or draw or two pairs (just saw a hand K-K against J-T and the A in the flop allowed the latter to see all the board until he got the second T so the kings were defeated by a trip but just because the ace somehow, gave protection to the J-T)
still the kings have more than 70% (in theory) of chances against any two, although they are only a pair and therefore just when facing elimination i will risk all chips preflop, otherwise a prefer a pot control if my stack is deep enough and don´t need to risk it
