There were ooh's and ahh's when A2 was behind on every street and lost to A3?
Pre-flop its 49%ish for a split.
First Card out was a 2, hence hes then ahead.
The other two flop cards are 33 and A2 is then drawing unbelievably thin.
Turn gives him a boat (albeit 22233 losing to 33322) and a 1 outer on the river.
River partially hits him in the sense that he improves his boat to 222AA but is still losing to 333AA.
Oh and Ahs - Yes getting it all on on the SB v BB with A2 making a boat and still losing, is that not a bit harsh!
