Tournament game of Texas hold’em. Hand is dealt, and goes to two players all the way to showdown. I show my cards A/4 and opponent shows 3 cards 8/6/3 clubs and makes no hand. They declare a misdeal and give him back his chips even though I had the winning pair of 4s with an A kicker. My understanding is that SA (significant action) was clear because he either called or bet all the way to showdown and therefore his hand would be dead correct?
