Either you would have to know (somehow) that the opponent has endless checks or you would have to search all checks in the qsearch (and check evasion responses) until you find somewhere to hide your king (not possible here) or you reach 50 move rule/rep draw (which is what you must find to prove that h7 is a draw). The variations are endless to reach 50 move rule. Hmmm...perhaps you could cheat a little bit by making an 8 move rule for this position?
