Question About the 1000 Bitcoin Puzzle

Let's assume theoretically that I found a private key from one of the wallets around puzzle 70 and now have access to this wallet. How do I take the bitcoin out of the wallet without being frontrun by bots before my initial withdrawal transaction finishes? Please give me a step by step solution and try to include important details as I'm not a professional in this sense aside from knowing how to run the keyscanner program.
