I absolutely love this app BUT the perfect play is inconsistent when it comes to holding J-10, Q-10, & K-10. For example, when dealt Q-10 suited with A, 3, 9 of various suits most of the time it will advise you to hold the Q-10. Sometimes it says Q-A. I compared the perfect play results to the analyze hand feature & got different answers for the exact same cards. The other area of inconsistency is being dealt 4 to a flush with 3 being to a royal. Perfect play will advise you to hold 3 to a royal but the analyze hand feature advises all 4. Ive played thousands of hands & did pretty detailed comparisons & those are the only 2 areas of inconsistencies Ive found. Would give 5 stars if those were corrected. Other than that - great app. Just like casino !
