Aces No Good

You would think to yourself "happy days" when you pick up AA on the button and then manage to flop a set with them but for Robert Csire it wasn't too good for him, action folded to Csire on the button & puts in a raise to 600 SB folds and Mark Smyth in the BB calls. 

Dealer spreads Ad8s2s with Smyth check calling an 800 bet, Turn Qs Smyth once again checks to the bettor who lead for 1,500 no Smyth check raises to 3,500 Csire dwells briefly before calling, river is dealt a spade now putting 4 spades on the board and it slows down both players as it went check/check Csire flipped AcAh for a set but Smyth was cagey with his check as he turns over 3s5s thinking that he might be goosed on the river.
