Hello. I think if he flopped a set or 2 pair on a draw heavy board he would raise for sure. this is situation where in a vacuum I would call every time unless I have reason to believe they would play a set or 2 pair in this weird fashion, it is 1-2 after all they do weird stuff in 1-2. but I’d for sure call the river and I would put the Villan on range with A9 or K9 or maybe even 8 9. also don’t forget to consider the Diamond draws that missed that he could have complete air on, and could’ve called the clock because couldn’t take the pressure anymore kinda like Shwartz calling clock on Frederico Butteroni in main event. probably misspelled both their names.
and if you really tanked 8 minutes at 1-2 I can see them calling the clock. shouldn’t take that long even in a home game, go through the actions preflop and player habits and tendencies to identify ranges.
