Yamagishi Making Moves?

Rob Limpert opened to 10k under the gun before Colten Yamagishi made it 25k to go from the button. Limpert called to the 5♠10♣A♥ flop and they both checked to the Q♦ turn.

Limpert fired 15k on the turn only to see Yamagishi bump it up to 50k. Limpert tank-folded before Yamagishi revealed a deuce as he scooped in the pot.
