Hi TPE!

We were sitting pretty deep, with 15 minute blind levels, 14 or so left in a stars.eu $8.80 1R1A.

I feel like it is a big mistake to call the river here. Ingame my thinking was, villain might try to level and rep the 8, but when thinking about it, this doesn't make much sense here (?). He should always have twopair+ when leading river I guess.

I would be interested to hear some reasoning how to play this spot and why folding is probably +EV.

Also I wonder if my turn sizing should be bigger as there are now straight and flush draws on the board.
