Hello All. Can somebody refer me to where I can find this rule in the TDA poker rule book.

Scenario: two players heads-up on the river.

Player 1 checks. Player 2 betts 100. Player 1 then jams the remainder of his 135 in chips without saying a word. Immediately after jamming he tables open his hand. Player 2 then opens his hand showing the "nuts" without officially saying "call".

Is Player 2 entitled to the 135 or only the 100 he originally bet
