BB was loose rec and could have anything which was why I cbet but unsure about it. Turn also not sure of the bet since I think its better for villain range but since I picked up equity and can't x/c just went with it. River I think some hands I expect to fold I block (66 - 88) but I don't block the 56s, 57s since the 5 is diamond so expect these to fold and all club draws and 33 and I'm at the exact bottom of my range so I jammed.

However when I plugged this in GTO+ solver our hand is 100% check on river but 78s is 100% jam (even clubs). Anyone know why this is?

It also does other things I can't reason out - calls river with 75cc, 75ss and folds 75hh, but calls 56cc,hh folds 56 spades. Is there always reasoning behind these plays or does it randomize?

Thanks in advance
