No history a big stack that was just moved here. Sick river obviously putting 4 card straight on board. What do you guys think? How could i have played it better to get more money. Does his range have a big Ace in it especially after he checks to me? Obv given he had an under set I should have raised the flop, but with top set on a dry board is that ever a good play not knowing what he has?
