Hi,

A. Suggestions for the most user friendly software, or otherwise best SW for practicing my preflop game (RFI, 3 bet, 4 bet spots). Is Snowie the best ?

B. Also, post flop spots? I'm aware about Monkersolver and PIO. Is there anything like Vision SW available for NLH?

C. And additionally, what about for NL tourneys would the same apply?
